Dihydrofolate reductase (DHFR) has been explored as a target for the development of agents for wide variety of human diseases, including cancer, autoimmune and infectious diseases. Several metal complexes are being used in management of cancer. The square planar Pt(II) complex, cis PtCl2(NH3)2 turned out to be even more effective at forcing filamentous growth. Cisplatin is an inorganic heavy metal complex that has activity similar to cell-cycle-phase-nonspecific alkylating agents such as cyclophosphamide and some other Ni and Cu metal complexes. It produces intrastrand DNA cross-link and form DNA adducts, thus inhibiting the synthesis of DNA, RNA and proteins preferentially. in silico Screening of platinum metal complexes was performed by Vlife MDS 4.3 software. In this procedure, selection of molecule, selection of PDB, optimization of PDB and docking of molecules was carried out. Synthesis of metal complexes was done by multi component reaction method. Platinum metal complexes of quinazolinone Schiff bases prioritized by in silico studies were characterized by IR, TLC, NMR, XRD, FESEM and some physico-chemical parameters. Prioritized molecules were further evaluated by in vitro anticancer cell line assay on ten cell lines with adriamycin as standard. The results showed that the platinum metal complexes of qunazolinone Schiff bases can be potential anticancer agents through DHFR inhibitory mechanism.
二氢叶酸还原酶(DHFR)已被视为一种靶标,用于开发治疗各种人类疾病(包括癌症、自身免疫性疾病和传染性疾病)的药物。有几种金属复合物正被用于治疗癌症。方形平面铂(II)复合物顺式 PtCl2(NH3)2 在强迫丝状生长方面更为有效。顺铂是一种无机重金属复合物,其活性类似于细胞周期阶段非特异性烷化剂,如环磷酰胺和其他一些镍和铜金属复合物。它能产生链内 DNA 交联并形成 DNA 加合物,从而优先抑制 DNA、RNA 和蛋白质的合成。铂金属复合物的筛选是通过 Vlife MDS 4.3 软件进行的。筛选过程包括分子选择、PDB 选择、PDB 优化和分子对接。金属配合物的合成采用多组分反应法。通过 IR、TLC、NMR、XRD、FESEM 和一些物理化学参数对硅学研究优先考虑的喹唑啉酮席夫碱铂金属配合物进行了表征。以阿霉素为标准,对十种细胞系进行了体外抗癌细胞系测定,进一步评估了优先分子。结果表明,坤唑啉酮席夫碱的铂金属配合物可以通过 DHFR 抑制机制成为潜在的抗癌剂。
