Streptonigrin is a natural product produced by Streptomyces flocculus, has both anti-tumor and anti-bacterial activity. Streptonigrin acts as a pan-PAD inhibitor (IC50s: 48.3±34.2 µM, 26.1±0.3 µM, 0.43±0.03 µM, and 2.5±0.4 µM for PAD1, PAD2, PAD3, and PAD

PAD2-IN-1, a benzimidazole-based derivative, is an efficacious and specific inhibitor of protein arginine deiminase 2 (PAD2). Demonstrating remarkable selectivity, PAD2-IN-1 exhibits a 95-fold higher affinity for PAD2 in comparison to PAD4 and a 79-fold higher affinity than PAD3.

PAD-IN-2 是 pad4 的有效抑制剂，IC50 值 <1 μM，能够用于研究自身免疫性疾病和癌症，如类风湿性关节炎、血管炎、系统性红斑狼疮、皮肤红斑狼疮、囊性纤维化、溃疡性结肠炎、哮喘、多发性硬化和牛皮癣。

PAD4-IN-2（化合物5i）是一种具有IC50为1.94 μM的PAD4抑制剂。该化合物能够通过特异性抑制中性粒细胞内PAD4-H3cit-NETs途径，从而有效抑制小鼠体内肿瘤生长。

N-[1-(Aminocarbonyl)-4-[(2-chloro-1-iminoethyl)amino]butyl]benzamide 是Cl-amidine (S 构型)的消旋形式。Cl-amidine 口服有效的 PAD 抑制剂。

YW3-56 is an inhibitor of protein arginine deiminase 2 (PAD2) and PAD4 (IC50s = 0.5-1 and 1-5 μM, respectively).1It inhibits the growth of U2OS osteosarcoma cells (IC50= ~2.5 μM) in a p53-dependent mannerviainduction of SESN2 and subsequent inhibition of mTORC1. YW3-56 (10 mg kg) reduces tumor growth in an S-180 murine sarcoma tumor model. It also inhibits tumor growth in the 1883 MDA-MB-231 breast cancer bone metastasis mouse xenograft model.2 1.Wang, Y., Li, P., Wang, S., et al.Anticancer peptidylarginine deiminase (PAD) inhibitors regulate the autophagy flux and the mammalian target of rapamycin complex 1 activityThe Journal of Biological Chemisty287(31)25941-25952(2012) 2.Wang, S., Chen, X.A., Hu, J., et al.ATF4 gene network mediates cellular response to the anticancer PAD inhibitor YW3-56 in triple-negative breast cancer cellsMol.

YW3-56 is a potent peptidylarginine deiminase (PAD) inhibitor, with an IC50 of 1-5 μM for PAD4. Compared with Cl-amidine, YW3-56 shows >60-fold increase in cell growth inhibition efficacy (IC50 about 2.5 μM) but only 5-fold increase in PAD4 inhibition (IC sub>50 about 1-5 μM). At 2-4 μM concentrations, YW3-56 displays mainly cytostatic effects by slowing cell division, whereas at higher concentrations, it exerts cytotoxic effects by altering cell morphology and killing cells[1].

Sarpogrelate-d3 HCl 是 Sarpogrelate HCl 的氘代化合物。Sarpogrelate HCl 的 CAS 号为 135159-51-2。Sarpogrelate hydrochloride 是一种选择性5-HT2R拮抗剂，可用于研究与血栓形成有关的血管疾病，对 5-HT2A、5-HT2B 和 5-HT2C 受体的pKi值分别为 8.52、6.57 和 7.43。

Resolvin E2 (RvE2) is a member of the specialized pro-resolving mediator (SPM) family of bioactive lipids.1It is produced from eicosapentaenoic acidviaan 18-HEPE intermediate, which is formed by aspirin-acetylated COX-2-mediated oxidation of EPA, by 5-lipoxygenase (5-LO) in human polymorphonuclear (PMN) neutrophils.2,3RvE2 (20 ng/animal) inhibits increases in inflammatory exudate neutrophil infiltration in a mouse model of peritonitis induced by zymosan A .3Hepatic RvE2 levels are increased in mice fed normal chow, as well as in a mouse model of high-fat diet-induced non-alcoholic fatty liver disease (NAFLD), by dietary supplementation with EPA.4Plasma levels of RvE2 are increased by dietary supplementation with fish oil containing ω-3 polyunsaturated fatty acids (PUFAs) in patients with peripheral artery disease or chronic kidney disease.1,5,6 1.Chiang, N., and Serhan, C.N.Specialized pro-resolving mediator network: An update on production and actionsEssays Biochem.64(3)443-462(2020) 2.Tjonahen, E., Oh, S.F., Siegelman, J., et al.Resolvin E2: Identification and anti-inflammatory actions: Pivotal role of human 5-lipoxygenase in resolvin E series biosynthesisChemistry & Biology131193-1202(2006) 3.Sungwhan, F.O., Pillai, P.S., Recchiuti, A., et al.Pro-resolving actions and stereoselective biosynthesis of 18S E-series resolvins in human leukocytes and murine inflammationJ.
