DC75380 Leucovorin calcium hydrate Leucovorin calcium is a n active metabolite of folic acid (also called folinic acid and citrovorum factor), which does not require metabolism by dihydrofolate reductase, the molecular target of folate antagonist-type chemotherapeutic drugs. Leucovorin calcium counteracts the toxic effects of these medications, 'rescuing' the patient while permitting the antitumor activity of the folate antagonist. This agent also potentiates the effects of fluorouracil and its derivatives by stabilizing the binding of the drug's metabolite to its target enzyme, thus prolonging drug activity.
DC75381 Dacomitinib Dacomitinib, also known as PF-299 and PF-00299804 ; or PF299804, is an orally bioavailable, highly selective, second-generation small-molecule inhibitor of the pan-epidermal growth factor receptor (EGFR) family of tyrosine kinases (ErbB family) with potential antineoplastic activity. Dacomitinib specifically and irreversibly binds to and inhibits human EGFR subtypes, resulting in inhibition of proliferation and induction of apoptosis in EGFR-expressing tumor cells. EGFRs play major roles in tumor cell proliferation and tumor vascularization, and are often overexpressed or mutated in various tumor cell types.
DC75382 CP640186 HCl CP-640186 is a potent inhibitor of mammalian ACCs and can reduce body weight and improve insulin sensitivity in test animals. CP-640186 has recently been shown to be a potent inhibitor of isoforms of mammalian ACCs with IC50 values of about 55 nM. This is currently the only reported potent inhibitor of mammalian ACCs. In cell cultures as well as in animal models, CP-640186 can reduce tissue malonyl-CoA levels, inhibit fatty acid biosynthesis, and stimulate fatty acid oxidation. Most importantly, CP-640186 can reduce body fat mass and body weight, and improve insulin sensitivity, validating ACCs as targets for antiobesity and antidiabetes drugs.
DC75383 K145 HCl salt K145 is a selective sphingosine kinase-2 (SphK2) inhibitor and anticancer agent. K145 inhibited the activity of SphK2 in a dose-dependent manner with an IC50 of 4.30±0.06 µM. K145 also exhibited inhibitory effects on the growth of U937 cells as well as apoptotic effects in U937 cells. K145 exhibits comparable in vivo anti-tumor activity to tamibarotene, while concomitantly exhibiting less toxicity in this U937 xenograft cancer model.
DC75384 Rociletinib Rociletinib, also known as AVL-301 and CO1686, is an orally available small molecule, irreversible inhibitor of epidermal growth factor receptor (EGFR) with potential antineoplastic activity. EGFR inhibitor CO-1686 binds to and inhibits mutant forms of EGFR, including T790M, thereby leading to cell death of resistant tumor cells. Compared to other EGFR inhibitors, CO-1686 inhibits T790M, a secondary acquired resistance mutation, as well as other mutant EGFRs and may have therapeutic benefits in tumors with T790M-mediated resistance to other EGFR tyrosine kinase inhibitors.
DC75385 Irinotecan HCl trihydrate Irinotecan hydrochloride is the hydrochloride salt of a semisynthetic derivative of camptothecin, a cytotoxic, quinoline-based alkaloid extracted from the Asian tree Camptotheca acuminata. Irinotecan, a prodrug, is converted to a biologically active metabolite 7-ethyl-10-hydroxy-camptothecin (SN-38) by a carboxylesterase-converting enzyme. One thousand-fold more potent than its parent compound irinotecan, SN-38 inhibits topoisomerase I activity by stabilizing the cleavable complex between topoisomerase I and DNA, resulting in DNA breaks that inhibit DNA replication and trigger apoptotic cell death.
DC75386 Clodronate sodium hydrate Clodronic acid or clodronate disodium is a bisphosphonate and a bone resorption inhibitor and antihypercalcemic agent. It is used in experimental medicine to selectively deplete for macrophages. Clodronate binds to calcium and inhibits osteoclastic bone resorption and hydroxyapatite crystal formation and dissolution, resulting in a reduction of bone turnover. This agent may control malignancy-associated hypercalcemia, inhibit osteolytic bone metastasis and decrease pain.
DC75387 Duvelisib (IPI-145) Duvelisib, also known as IPI-145 and INK-1197, is an orally bioavailable, highly selective and potent small molecule inhibitor of the delta and gamma isoforms of phosphoinositide-3 kinase (PI3K) with potential immunomodulating and antineoplastic activities. Upon administration, PI3K delta/gamma inhibitor IPI 145 prevents the activation of the PI3K delta/gamma-mediated signaling pathways which may lead to a reduction in cellular proliferation in PI3K delta/gamma-expressing tumor cells. Unlike other isoforms of PI3K, the delta and gamma isoforms are overexpressed primarily in hematologic malignancies and inflammatory and autoimmune diseases.
DC75388 Paclitaxel-SMCC Paclitaxel-SMCC is a paclitaxel derivative with a SMCC linker. (Succinimidyl-4-( N-maleimidomethyl)cyclohexane-1-carboxylate). Maleimide in Paclitaxel-SMCC can react with sulfhydryl groups at pH 6.5-7.5 to form a stable thioether bond. Paclitaxel-SMCC can be used to synthesize Paclitaxel bioconjugates with proteins, enzymes; antobodies, antigens, and other biopolymers. Paclitaxel-SMCC is often used for drug delivery research.
DC75389 Indomethacin Indomethacin is a synthetic nonsteroidal indole derivative with anti-inflammatory activity and chemopreventive properties. As a nonsteroidal anti-inflammatory drug (NSAID), indomethacin inhibits the enzyme cyclooxygenase, thereby preventing cyclooxygenase-mediated DNA adduct formation by heterocyclic aromatic amines. This agent also may inhibit the expression of multidrug-resistant protein type 1, resulting in increased efficacies of some antineoplastic agents in treating multi-drug resistant tumors. In addition, indomethacin activates phosphatases that inhibit the migration and proliferation of cancer cells and downregulates survivin, which may result in tumor cell apoptosis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
DC75390 Cilengitide TFA salt Cilengitide is a cyclic Arg-Gly-Asp peptide with potential antineoplastic activity. Cilengitide binds to and inhibits the activities of the alpha(v)beta(3) and alpha(v)beta(5) integrins, thereby inhibiting endothelial cell-cell interactions, endothelial cell-matrix interactions, and angiogenesis.
DC75391 Capmatinib Capmatinib, also known as INCB28060 and INC280, is an orally bioavailable inhibitor of the proto-oncogene c-Met (hepatocyte growth factor receptor [HGFR]) with potential antineoplastic activity. c-Met inhibitor INC280 selectively binds to c-Met, thereby inhibiting c-Met phosphorylation and disrupting c-Met signal transduction pathways. This may induce cell death in tumor cells overexpressing c-Met protein or expressing constitutively activated c-Met protein. Capmatinib was approved in 2020.
DC75392 Cevipabulin (free base) Cevipabulin (free base), also known as TTI-237, an antimicrotubule agent, is a small synthetic molecule of triazolopyrimidine derivative with potential antitumor activity. With a novel mechanism of action distinct from the action of other vinca alkaloid compounds, TTI-237 specifically binds to tubulin at the vinca site, and promotes the polymerization of tubulin into microtubules. TTI-237 stabilizes tubulin and inhibits microtubule disassembly. This results in cell cycle arrest at the G2/M phase, and leading to cell death.
DC75393 Cabozantinib free base Cabozantinib, also known as XL-184 and BMS-907351, is the s-malate salt form of cabozantinib, an orally bioavailable, small molecule receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. Cabozantinib strongly binds to and inhibits several RTKs, which are often overexpressed in a variety of cancer cell types, including hepatocyte growth factor receptor (MET), RET (rearranged during transfection), vascular endothelial growth factor receptor types 1 (VEGFR-1), 2 (VEGFR-2), and 3 (VEGFR-3), mast/stem cell growth factor (KIT), FMS-like tyrosine kinase 3 (FLT-3), TIE-2 (TEK tyrosine kinase, endothelial), tropomyosin-related kinase B (TRKB) and AXL. This may result in an inhibition of both tumor growth and angiogenesis, and eventually lead to tumor regression. Cabozantinib was approved by the U.S. FDA in November 2012 for the treatment of medullary thyroid cancer.
DC75394 Cabazitaxel-d6 Cabazitaxel-d6 is a deuterium labeled cabazitaxel. Cabazitaxel is a semi-synthetic derivative of the natural taxoid 10-deacetylbaccatin III with potential antineoplastic activity. Cabazitaxel binds to and stabilizes tubulin, resulting in the inhibition of microtubule depolymerization and cell division, cell cycle arrest in the G2/M phase, and the inhibition of tumor cell proliferation. Unlike other taxane compounds, this agent is a poor substrate for the membrane-associated, multidrug resistance (MDR), P-glycoprotein (P-gp) efflux pump and may be useful for treating multidrug-resistant tumors. In addition, cabazitaxel penetrates the blood-brain barrier (BBB).
DC75395 CA-170 free base CA-170, also known as AUPM170 and PD-1-IN-17, is a programmed cell death-1 (PD-1) inhibitor. PD-1-IN-17 was first reported in patent WO2015033301A1, (Compound 4), inhibits 92% splenocyte proliferation at 100 nM.
DC75396 Bendamustine HCl Bendamustine hydrochloride is the hydrochloride salt of bendamustine, a bifunctional mechlorethamine derivative with alkylator and antimetabolite activities. Bendamustine possesses three active moieties: an alkylating group; a benzimidazole ring, which may act as a purine analogue; and a butyric acid side chain. Although its exact mechanism of action is unknown, this agent appears to act primarily as an alkylator. Bendamustine metabolites alkylate and crosslink macromolecules, resulting in DNA, RNA and protein synthesis inhibition, and, subsequently, apoptosis. In October 2008, the FDA granted further approval to market Treanda for the treatment of indolent B-cell non-Hodgkin's lymphoma (NHL) that has progressed during or within six months of treatment with rituximab or a rituximab-containing regimen.
DC75397 Copanlisib free base Copanlisib, also known as BAY 80-6946, is a potent phosphoinositide 3-kinase (PI3K) inhibitor. Copanlisib inhibits the activation of the PI3K signaling pathway, which may result in inhibition of tumor cell growth and survival in susceptible tumor cell populations. Activation of the PI3K signaling pathway is frequently associated with tumorigenesis and dysregulated PI3K signaling may contribute to tumor resistance to a variety of antineoplastic agents. Copanlisib was approved for the treatment of adult patients experiencing relapsed follicular lymphoma who have received at least two prior systemic therapies.
DC75398 Buparlisib (BKM120) Buparlisib, also known as BKM120, is an orally bioavailable specific oral inhibitor of the pan-class I phosphatidylinositol 3-kinase (PI3K) family of lipid kinases with potential antineoplastic activity. PI3K inhibitor BKM120 specifically inhibits class I PIK3 in the PI3K/AKT kinase (or protein kinase B) signaling pathway in an ATP-competitive manner, thereby inhibiting the production of the secondary messenger phosphatidylinositol-3,4,5-trisphosphate and activation of the PI3K signaling pathway.
DC75399 Baricitinib Baricitinib, also known as INCB028050 or LY3009104, is a selective orally bioavailable JAK1/JAK2 inhibitor with nanomolar potency against JAK1 (5.9 nM) and JAK2 (5.7 nM). INCB028050 inhibits intracellular signaling of multiple proinflammatory cytokines including IL-6 and IL-23 at concentrations <50 nM. INCB028050 was also effective in multiple murine models of arthritis, with no evidence of suppression of humoral immunity or adverse hematologic effects. Baricitinib was approved for the treatment of rheumatoid arthritis (RA) in the United States.
DC75400 Apalutamide (ARN-509) Apalutamide, also known as ARN-509 and JNJ-56021927 , is an androgen receptor antagonist with potential antineoplastic activity. ARN-509 binds to AR in target tissues thereby preventing androgen-induced receptor activation and facilitating the formation of inactive complexes that cannot be translocated to the nucleus. This prevents binding to and transcription of AR-responsive genes. This ultimately inhibits the expression of genes that regulate prostate cancer cell proliferation and may lead to an inhibition of cell growth in AR-expressing tumor cells.
DC75401 CX4945 (Silmitasertib) Silmitasertib, also know as CX-4945, is an orally bioavailable small-molecule inhibitor of CK2 with potential antineoplastic activity. CK2 inhibitor CX-4945 selectively binds to and inhibits the enzyme casein kinase II (CK2), which may lead to an inhibition of cellular proliferation. CK2, a protein kinase often overexpressed in a variety of cancer cell types, appears to be correlated with malignant transformation, tumor growth and survival.
DC75402 Talazoparib Talazoparib, also known as BMN-673 and MDV-3800, is an orally bioavailable inhibitor of the nuclear enzyme poly(ADP-ribose) polymerase (PARP) with potential antineoplastic activity (PARP1 IC50 = 0.57 nmol/L). Talazoparib acts as an inhibitor of poly ADP ribose polymerase(PARP) which aids in single strand DNA repair. Cells that have BRCA1/2 mutations are susceptible to the cytotoxic effects of PARP inhibitors because of an accumulation of DNA damage. Talazoparib is theorized to have a higher potency than olaparib due to the additional mechanism of action called PARP trapping. PARP trapping is the mechanism of action where the PARP molecule is trapped on the DNA, which interferes with the cells ability to replicate. Talazoparib is found to be ~100 fold more efficient in PARP trapping than olaparib. Talazoparib was approved in 2018 by FDA.
DC75403 Abrocitinib Abrocitinib, also known as PF-04965842, is an oral Janus Kinase 1 inhibitor being investigated for treatment of plaque psoriasis. In January 2022, FDA approved abrocitinib for adults with moderate-to-severe atopic dermatitis. Abrocitinib at a dose of either 200 mg or 1 g once daily resulted in significantly greater reductions in signs and symptoms of moderate-to-severe atopic dermatitis than placebo at weeks 12 and 16. The 200-mg dose, but not the 100-mg dose, of abrocitinib was superior to dupilumab with respect to itch response at week 2.
DC75404 Abaperidone free base Abaperidone, also known as FI 8602, is an atypical antipsychotic. Reduced hsp70 in the prefrontal cortex may play a critical role in the etiology of many schizophrenia symptoms and may be linked to an atypical profile of antipsychotics, such as abaperidone.
DC75405 Birabresib Birabresib, also known as OTX015 and MK-8628, a potent BET bromodomian inhibitor, which targets the BET bromodomain proteins 2, 3, and 4 (BRD2/3/4). BRDs 2, 3, and 4 are considered potential cancer targets because of their pivotal role in regulating the transcription of growth-promoting genes and cell cycle regulators. OTX015 is the first BRD2/3/4 inhibitor to enter clinical trials. OTX015 showed antiproliferative activity in a large panel of cell lines derived from mature B-cell lymphoid tumors with median IC50 of 240 nmol/L, without significant differences among the different histotypes.
DC75406 AVN-101 HCl AVN-101 is a very potent 5-HT7 receptor antagonist, with slightly lesser potency toward 5-HT6, 5-HT2A, and 5HT-2C receptors. It is a milti-target drug candidate for the treatment of CNS disorders.
DC75407 Bazedoxifene acetate Bazedoxifene, also known as WAY-140424, is a third generation selective estrogen receptor modulator (SERM), developed by Pfizer following the completion of their takeover of Wyeth Pharmaceuticals. In late 2013, Pfizer received approval for bazedoxifene as part of the combination drug DUAVEE in the prevention (not treatment) of postmenopausal osteoporosis. Bazedoxifene is an indole-based ER ligand that binds to both ERα (IC50 = 26 nM) and ERβ (IC50 = 99 nM).
DC75408 Mirogabalin free base Mirogabalin, also known as DS-5565, is an α2δ-1 ligand being developed for pain associated with diabetic peripheral neuropathy, fibromyalgia, and postherpetic neuralgia. Mirogabalin was estimated to be 17-fold more potent than pregabalin. Mirogabalin is being developed by Daiichi Sankyo and related to drugs such as gabapentin and pregabalin. Similarly to these drugs, mirogabalin binds to the α2δ calcium channels (1 and 2), but with significantly higher potency than pregabalin. It has shown promising results in Phase II clinical trials for the treatment of diabetic peripheral neuropathic pain.
DC75409 Ibipinabant Ibipinabant, also known as BMS-646256, JD-5001 and SLV-319, is a potent and highly selective CB1 antagonist. It has potent anorectic effects in animals, and was researched for the treatment of obesity, although CB1 antagonists as a class have now fallen out of favour as potential anorectics following the problems seen with rimonabant, and so ibipinabant is now only used for laboratory research, especially structure-activity relationship studies into novel CB1 antagonists.
