MK-8245 trifluoroacetate is a liver-targeting inhibitor of stearoyl-CoA desaturase (SCD) with IC50 of 1 nM for human SCD1 and 3 nM for both rat SCD1 and mouse SCD1, with anti-diabetic and anti-dyslipidemic efficacy. IC50 value: 1 nM (hSCD1) Target: SCD1 in vitro: MK-8245, a phenoxy piperidine isoxazole derivative, has been identified as a potent and liver-specific SCD inhibitor. It contains a tetrazole acetic acid moiety, which is the key molecule for OATPs recognition and liver-targeting. MK-8245 displays similar potencies against human, rat and mouse SCD1 with IC50 values of 1 nM for human SCD1 and 3 nM for both rat SCD1 and mouse SCD1. MK-8245 exhibits a significant SCD inhibition in the rat hepatocyte assay which contains functional, active OATPs with IC50 of 68 nM, while being only weakly active in the HepG2 cell assay which is devoid of active OATPs with IC50 of ~1 μM. MK-8245 displays highly selective activity for the Δ-5 and Δ-6 desaturases (i.e., >100000 μM vs rat and human Δ5D and Δ6D as assessed in the HepG assay. in vivo: Administration of MK-8245 at 10 mg kg in mice exhibits a tissue distribution profile concentrated in the liver. It shows a liver-to-Harderian gland ratio of 21, suggesting a high degree of liver-targeting compared to a systemically distributed compound with liver-to-Harderian gland ratio of 1.5. Oral dosing of MK-8245 in mice, rats, dogs, and rhesus monkeys demonstrates that MK-8245 is distributed mainly to the liver, with low exposure in tissues associated with potential adverse events. The liver-to-skin ratios are >30:1 in all four species. Administration of MK-8245 to eDIO mice before the glucose challenge improves glucose clearance in a dose-dependent manner with ED50 of 7 mg kg.

USP1-IN-11 (compound 38-P2) 是一种选择性、可逆和非竞争性的USP1(Ubiquitin-specific protease1)抑制剂。它通过激活DDR (DNA damage repair) 通路来诱导细胞周期停滞与细胞凋亡 (Apoptosis)，从而抑制细胞存活。USP1-IN-11 可提高Olaparib耐药细胞的敏感性，且在BRCA功能正常的癌细胞中与Andrographolide具有协同作用。在MDA-MB-436异种移植模型中，该化合物展示出显著的剂量依赖性抗肿瘤效果。

Ro 46-844 是选择性非肽内皮素受体拮抗剂。它对ETB(IC50: 34-69 nM) 的选择性比ETA 受体 (IC50: 6800 nM) 高的100倍以上。

Propargyl-NH-PEG3-C2-NHS ester is a non-cleavable triethylene glycol linker with propargyl and N-hydroxysuccinimide functional groups. It is utilized in the synthesis of antibody-drug conjugates (ADCs)[1].

GSK172981 is a non-peptide tachykinin NK3 receptor antagonist with a high affinity for the recombinant human (PK (I) value 7.7) and native guinea pig (PK (I) value 7.8) tachykinin NK3 receptor. In vitro, the functional evaluation showed that GSK172981 was

Nolpitantium Free Base is a highly selective nonpeptide antagonist of neurokinin-1 (NK1) receptor. Nolpitantium potently, selectively and competitively inhibited substance P binding to NK1 receptors from various animal species, including humans. In vitro, it was a potent antagonist in functional assays for NK1 receptors such as [Sar9, Met(O2)11]substance P-induced endothelium-dependent relaxation of rabbit pulmonary artery and contraction of guinea-pig ileum. Up to 1 mkM, Nolpitantium had no effect in bioassays for NK2 and NK3 receptors. The antagonism exerted by Nolpitantium toward NK1 receptors was apparently non-competitive, with pD2' values between 9.65 and 10.16 in the different assays. Nolpitantium also blocked in vitro [Sar9, Met(O2)11]substance P-induced release of acetylcholine from rat striatum. In vivo, Nolpitantium exerted highly potent antagonism toward [Sar9, Met(O2)11]substance P-induced hypotension in dogs, bronchoconstriction in guinea-pig) and plasma extrava......

DS-3801b 是一种具有 N-甲基苯胺结构的非大环内酯类 GPR38 激动剂，可用于研究功能性胃肠道疾病。

The protein p53, often called the 'guardian of the genome,' is a transcription factor that is activated in response to cellular stress (low oxygen levels, heat shock, DNA damage, etc.) and acts to prevent further proliferation of the stressed cell by promoting cell cycle arrest or apoptosis. Its role as a tumor suppressor is evident by the observation that approximately 50% of human tumors have mutated or non-functional p53. PK7242 is an inducer of reactivation of mutant p53 in cancer cells. In cancer cells carrying the Y220C mutant, PK7242 binds to the p53-Y220C core domain and induces growth inhibition, cell-cycle arrest, and apoptosis.
