Publication: [1]. RBN-2397-Inhibiting PARP7, a Key monoPARP Cancer Dependency [2]. Melissa Vasbinder, et al. RBN-2397: A First-in-Class PARP7 Inhibitor Targeting a Newly Discovered Cancer Vulnerability in Stress-Signaling Pathways.
Description: RBN-2397 is a potent, accross species and orally active NAD+ competitive inhibitor of PARP7 (IC50<3 nM). RBN-2397 selectively binds to PARP7 (Kd=0.001 μM) and restores interferon (Type I) signaling. RBN-2397 has the potential for the study of advanced or metastatic solid tumors[1][2].
In Vivo: RBN-2397 (oral administration; 3-100 mg/kg; once daily; 24-32 days) induces tumor-specific adaptive immune memory in CT26 syngeneic model with durable complete responses in CT26 tumor-bearing BALB/c mice[2]. RBN-2397 (oral administration; 3-100 mg/kg; once daily; 32 days) causes complete regressions at the dose 100 mg/kg and exerts a dose-dependent effects on tumor growth at dose levels of ≥30 mg/kg[2]. The half-life (t1/2) of RBN-2397 in vivo is 325 mins[2]. Animal Model: CB17 SCID mice with NCI-H1373 xenografts[2] Dosage: 3 mg/kg, 10mg/kg, 30 mg/kg, 100 mg/kg Administration: Oral administration; once daily; 24-32 days Result: Decreased tumor volume and exerted anti-tumor effects.
In Vitro: RBN-2397 (0.0001-100 μM; 24 hours) inhibits cells proliferation with an IC50 value of 20 nM in NCI-H1373 lung cancer cells[2]. RBN-2397 (0.4 nM-1 μM; 24 hours) shows a restoration of type I IFN response by an increase in STAT1 phosphorylation as a dose-dependent manner in NCI-H1373 human lung cancer cells[2]. RBN-2397 (0.0001-1 μM; 24 hours) inhibits cell MARylation in a cell biochemial assay with an EC50 value of 1 nM[2]. Cell Proliferation Assay[2] Cell Line: NCI-H1373 lung cancer cells Concentration: 0.0001 μM; 0.001 μM; 0.001 μM; 0.1 μM; 1 μM; 10 μM; 100 μM Incubation Time: 24 hours Result: Blocked cell proliferation. Western Blot Analysis[2] Cell Line: NCI-H1373 lung cancer cells Concentration: 0.4 nM-1 μM Incubation Time: 24 hours Result: Increased p-STAT1 protein expression.

DC33635 DODAP DODAP, also known as 1,2-Dioleoyl-3-dimethylammonium-propane, is a cationic lipid. It has been used as a component in liposomes that can be used to encapsulate siRNA, immunostimulatory oligodeoxynucleotides, antisense oligonucleotides, or chemotherapeutic agents for in vitro and in vivo delivery.
DC58047 DSPE-PEG 2000 PEG2000-DSPE is used for creating micelles that are able to carry drugs with low solubility.
DC31000 LP-01 LP-01 is an ionizable cationic amino lipid (pKa = ~6.1). It has been used in the generation of lipid nanoparticles (LNPs). LNPs containing LP-01 and encapsulating both Cas9 mRNA and modified single-guide RNA (sgRNA) for the transport protein transthyretin (Ttr) induce gene editing in liver cells in mice in a dose-dependent manner resulting in reduced serum Ttr levels for at least 12 months.
DC66546 R-Sirpiglenastat R-Sirpiglenastat is the R- isomer of Sirpiglenastat(DRP-104).Sirpiglenastat (DRP104) is a broad acting glutamine antagonist. Sirpiglenastat has anticancer effects by directly targeting tumor metabolism and simultaneously inducing a potent antitumor immune response.
DC60597 AZD0780 AZD0780 is the first oral small molecule PCSK9 inhibitor for the treatment of hypercholesterolemia.
DC66114 FAPI-46 FAPI46 is a quinoline-based fibroblast activation protein (FAP)-targeted radiotracer. FAPI-46 has higher tumor uptake and prolonged tumor accumulation. FAPI 46 can be used for tumor imaging of a multitude of different cancers.
DC60580 Endosidin5(ES5) Endosidine 5 (ES5), is one of the most potent small molecules interferes with recycling endosomes through Annexin A6, thereby promoting the release and expression of mRNA into the cytoplasm. The delivered mRNAs is greatly enhanced via inhibition of endocytic recycling in cells and in live mice. NAV2729 (NAV) and endosidin 5 (ES5), resulted in significant enhancement (1.5–2 folds) of LNP-mediated delivery of Fluc mRNAs. Incubation of NAV and ES5 together caused modest further increases in Fluc expression in comparison to the sole application of either compound.
DC90056 PLX-5622 HCl form (water solubility form) PLX5622 is the HCl salt form of PLX-5622, which has better water solubility.PLX-5622 is a highly selective brain-penetrant CSF1R inhibitor (IC50=0.016 µM; Ki=5.9 nM) allowing for extended and specific microglial elimination, preceding and during pathology development.
DC60559 PT-179 PT-179 is a new orthogonal immunomodulatory drug (IMiD) derivative that binds CRBN but does not induce degradation of off-target proteins. PT-179 potently degrades proteins fused to SD40 at either the N or C terminus.
DC65841 MC1 MC1 is a selective and potent inhibitor for COX-2, and [11C]MC1 detected COX-2 in nonhuman primates after intracerebral injection of an inflammogen.
