Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, European Journal of Medicinal Chemistry called Purine/purine isoster based scaffolds as new derivatives of benzamide class of HDAC inhibitors, Author is Nepali, Kunal; Chang, Ting-Yu; Lai, Mei-Jung; Hsu, Kai-Cheng; Yen, Yun; Lin, Tony Eight; Lee, Sung-Bau; Liou, Jing-Ping, which mentions a compound: 5451-40-1, SMILESS is C2=NC1=C(C(=NC(=N1)Cl)Cl)[NH]2, Molecular C5H2Cl2N4, Product Details of 5451-40-1.
This study reports the design, synthesis and evaluation of a series of histone deacetylase (HDAC) inhibitors I (X = Cl, methylazanyl, (3-chloro-4-fluorophenyl)azanyl, etc.; Y = Cl, NH2, (2,4,6-trichloro-3,5-dimethoxyphenyl)azanyl; Z = N, CH; R = H, F) containing purine/purine isoster as a capping group and an N-(2-aminophenyl)-benzamide unit. In vitro cytotoxicity studies reveal that benzamide I (X = (3-chloro-4-fluorophenyl)azanyl; Y = NH2; Z = N; R = H) (A) suppressed the growth of triple-neg. breast cancer cells MDA-MB-231 (IC50 = 1.48μM), MDA-MB-468 (IC50 = 0.65μM), and liver cancer cells HepG2 (IC50 = 2.44μM), better than MS-275 and Chidamide. Compared to the well-known HDAC inhibitor SAHA, (A) showed a higher toxicity (IC50 = 0.33μM) in three leukemic cell lines, K-562, KG-1 and THP-1. Moreover, (A) was found to be equally virulent in the HDAC-sensitive and -resistant gastric cell lines, YCC11 and YCC3/7, resp., indicating the potential of (A) to overcome HDACi resistance. Furthermore, substantial inhibitory effects more pronounced than MS-275 and Chidamide were displayed by (A) towards HDAC1, 2 and 3 isoforms with IC50 values of 0.108, 0.585 and 0.563μM resp. Compound (A) also exhibited a potent antitumor efficacy in human MDA-MB-231 breast cancer xenograft mouse model, providing a potential lead for the development of anticancer agents.
There is still a lot of research devoted to this compound(SMILES：C2=NC1=C(C(=NC(=N1)Cl)Cl)[NH]2)Product Details of 5451-40-1, and with the development of science, more effects of this compound(5451-40-1) can be discovered.
