s 303

Amustaline (S-303) dihydrochloride is a nucleic acid-targeted alkylator recognized for its efficacy as a pathogen inactivation agent in blood components containing red blood cells. This compound comprises three key elements: an acridine anchor (a non-covalently bonding intercalator targeting nucleic acids), an effector (a bis-alkylator group that interacts with nucleophiles), and a linker (a flexible carbon chain with a labile ester bond, hydrolyzing at neutral pH to non-reactive products).

GPR35 agonist 4 (compound 10) 是一种有效的GPR35激动剂，其效价 pEC50为 5.86。GPR35 agonist 4 在人和大鼠 GPR35 中均显示高效价。精氨酸 3.36 的突变体可消除 GPR35 agonist 4 的激动剂功能。

BMS-303141是高效性和可渗透细胞的 ACL 抑制剂(IC50:0.13 μM)。

BKS3031A 是一种抑制剂，特异性结合于 αβ-微管蛋白 (αβ-tubulin) 的秋水仙碱结合位点，抑制微管的组装动力学。

SLP120701 is a potent and selective sphingosine kinase 2 inhibitor. Sphingosine-1-phosphate (S1P) is a ubiquitous, endogenous small molecule that is synthesized by two isoforms of sphingosine kinase (SphK1 and 2). Intervention of the S1P signaling pathway has attracted significant attention because alteration of S1P levels is linked to several disease states including cancer, fibrosis, and sickle cell disease.

TAS-303 is a selective norepinephrine reuptake inhibitor which displays significant norepinephrine transporter (NET) inhibitory activity toward serotonin or dopamine transporters. Radioligand-binding studies showed that TAS-303 selectively and potently inhibited [3H]norepinephrine binding to the human NET.

3β-OH-7-Oxocholenic acid is a bile acid.1 It is also a metabolite of 7β-hydroxy cholesterol in rats. Conjugated forms of 3β-OH-7-oxocholenic acid have been found in the urine of patients with Neimann-Pick disease type C.2,3 |1. Norii, T., Yamaga, N., and Yamasaki, K.
