Description: Osilodrostat (LCI699) is a potent inhibitor of human 11β-hydroxylase and aldosterone synthase with IC50 values of 2.5 and 0.7 nM, respectively.
Target: IC50: 2.5 nM (human 11β-hydroxylase), 0.7 nM (aldosterone synthase)[1]
In Vitro: Osilodrostat and pasireotide monotherapies are associated with significant changes in the histology and mean weights of the pituitary and adrenal glands, liver, and ovary/oviduct. Osilodrostat alone is associated with adrenocortical hypertrophy and hepatocellular hypertrophy. In combination, osilodrostat/pasireotide does not exacerbate any target organ changes and ameliorated the liver and adrenal gland changes observed with monotherapy. Cmax and AUC0–24h of osilodrostat and pasireotide increase in an approximately dose-proportional manner[1]. Osilodrostat treatment reduces urinary free cortisol in patients with Cushing's disease; 78.9% has normal urinary free cortisol at week 22. Treatment with osilodrostat is generally well tolerated[2].
Animal Administration: Rats: Sixty male and 60 female rats are randomized into single-sex groups to receive daily doses of pasireotide (0.3 mg/kg/day, subcutaneously), osilodrostat (20 mg/kg/day, orally), osilodrostat/pasireotide in combination (low dose, 1.5/0.03 mg/kg/day; mid-dose, 5/0.1 mg/kg/day; or high dose, 20/0.3 mg/kg/day), or vehicle for 13 weeks[1].

DC82301 IC-8 IC8 is an ionizable cationic lipid. It has been used in combination with other lipids for the formation of lipid nanoparticles (LNPs). Immunization with severe acute respiratory coronavirus 2 (SARS-CoV-2) spike glycoprotein mRNA in IC8- and manganese-containing LNPs induces IgG responses to SARS-CoV-2 Delta and Omicron variants in mice.1 Administration of mRNA encoding B7-H3 X CD3 bispecific T cell engaging (BiTE) antibodies in IC8-containing LNPs reduces tumor growth in MV4-11 and A375 mouse xenograft models.
DC46471 RP101988 RP101988, the major active metabolite of Ozanimod, is a selective, potent S1PR1 (sphingosine-1-phosphate receptor 1) agonist, with EC50s of 0.19 nM and 32.8 nM for S1PR1 and S1PR5, respectivlely.
DC45184 Hydrofurimazine Hydrofurimazine is a NanoLuc substrate whose enhanced aqueous solubility allows delivery of higher doses to mice. Hydrofurimazine enables sensitive bioluminescence imaging for either prolonged light production of high sensitivity.
DC37901 PD-173212 PD-173212 is a small molecule N-type calcium channel blocker.
DC37333 N,N-Diethyl-p-toluamide N,N-Diethyl-p-toluamide is a mosquito repellent.
DC37321 AI3-15902 AI3-15902 is a biochemical.
DC37283 Methyl phenylcarbamate Methyl phenylcarbamate is a biochemical.
DC37252 Ampyrone Ampyrone is a metabolite of AMINOPYRINE with analgesic and anti-inflammatory properties. It is used as a reagent for biochemical reactions producing peroxides or phenols. Ampyrone stimulates LIVER MICROSOMES and is also used to measure extracellular water.
DC37245 Piperonyl butoxide Piperonyl butoxide (PBO) is an organic compound used as a component of pesticide formulations. It is a waxy white solid. It is a synergist. That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.[1] It is a semisynthetic derivative of safrole.
DC36443 DC-Chol DC-Chol is a cationic cholesterol derivative. DC-Chol, as a component of lipoplexes with DOPE, has been used for transfection of mRNA into A549 cells without affecting cell viability. Incubation of DC-chol/DOPE liposomes or lipoplexes with human whole blood has no effect on neutrophil elastase or β-thromboglobulin levels or the number of platelets and red and white blood cells, indicating hemocompatibility. DC-Chol has also been widely used in the synthesis of liposomes for the delivery of siRNA, DNA, and chemotherapeutic agents into cells and mice.
