Jiao, Peili;Wang, Yuxi;Mao, Beibei;Wang, Bingding;Zhong, Yi;Jin, Hongwei;Zhang, Lihe;Zhang, Liangren;Liu, Zhenming published 《Discovery of 2-(2-aminobenzo[d]thiazol-6-yl) benzo[d]oxazol-5-amine derivatives that regulated HPV relevant cellular pathway and prevented cervical cancer from abnormal proliferation》 in 2020. The article was appeared in 《European Journal of Medicinal Chemistry》. They have made some progress in their research.Computed Properties of C7H5N3O2S The article mentions the following:
Herein, virtual screening was performed and 2-(2-aminobenzo[d]thiazol-6-yl) benzo[d]oxazol-5-amine derivatives I (R1 = H, NH2; R2 = H, NH2, NHC(O)NHC2H5) were designed, synthesized as antineoplastic agents, and evaluated for their anti-tumor activities. Among them, the most promising compound I (R = R1 = NH2) (II) showed specific anti-proliferation ability against HeLa cells (IC50 = 380 nM) as well as excellent inhibition of tumor growth in the HeLa xenograft model without inducing obvious side effects. It is interesting that compound II displayed significant inhibition against HPV18-pos. cervical cell lines (HeLa) but not for HPV16-pos. cervical cell lines (SiHa). Further study demonstrated that a low concentration of compound II could lead to a cell cycle blockage at the G1 phase and promote cell apoptosis slightly (8.77%). Compound II also exhibited transcription repression, especially those associated with the oncoprotein E7 cellular pathway like E7/Rb/E2F-1/DNMT1, which were essential in tumorigenesis. Proteomics anal. revealed that E7 might be degraded through E3 ubiquitin ligases, which aligned with decreasing expression of E7 following the treatment of compound II. Taken together, it indicated that compound II could be a promising potential agent for cervical cancer treatment. To complete the study, the researchers used 6-Nitrobenzo[d]thiazol-2-amine (cas: 6285-57-0) .
6-Nitrobenzo[d]thiazol-2-amine(cas:6285-57-0) has been used:
as model analyte for voltammetric determination of electrochemically reducible organic substances;
in the synthesis of 2-methyl-4-nitro-2H-pyrazole-3-carboxylic acid[2-(cyclohexanecarbonylamino)benzothiazol-6-yl]amide derivatives;
in the preparation of push-pull nonlinear optical chromophores containing thiazole and benzothiazole acceptors;
as a base in dye production by diazotation reaction.
