    KDM5B (also known as PLU-1 and JARID1B) is 2-oxoglutarate and Fe2+ dependent oxygenase that acts as a histone H3K4 demethylase, which is a key participant in inhibiting the expression of tumor suppressors as a drug target. Here, we present the discovery of pyrazole derivatives compound 5 by structure-based virtual screening and biochemical screening with IC50 of 9.320 μM against KDM5B, and its subsequent

    Cancer is a multifactorial disease necessitating identification of novel targets for its treatment. Inhibition of Bcl-2 for triggered pro-apoptotic signaling is considered a promising strategy for cancer treatment. Within the current work, we aimed to design and synthesize a new series of benzimidazole- and indole-based derivatives as inhibitors of Bcl-2 protein. The market pan-Bcl-2 inhibitor, obatoclax, was the lead framework compound for adopted structural modifications. The obatoclax’s pyrrolylmethine linker was replaced with straight alkylamine or carboxyhydrazine methylene linkers providing the new compounds. This strategy permitted improved structural flexibility of synthesized compounds adopting favored maneuvers for better fitting at the Bcl-2 major hydrophobic pocket. Anti-cancer activity of the synthesized compounds was further investigated through MTT-cytotoxic assay, cell cycle analysis, RT-PCR, ELISA and DNA fragmentation. Cytotoxic results showed compounds 8a, 8b and 8c with promising cytotoxicity against MDA-MB-231/breast cancer cells (IC50 = 12.69 ± 0.84 to 12.83 ± 3.50 µM), while 8a and 8c depicted noticeable activities against A549/lung adenocarcinoma cells (IC50 = 23.05 ± 1.45 and 11.63 ± 2.57 µM, respectively). The signaling Bcl-2 inhibition pathway was confirmed by molecular docking where significant docking energies and interactions with key Bcl-2 pocket residues were depicted. Moreover, the top active compound, 8b, showed significant upregulated expression levels of pro-apoptotic/anti-apoptotic of genes; Bax, Bcl-2, caspase-3, -8, and -9 through RT-PCR assay. Improving the compound’s pharmaceutical profile was undertaken by introducing 8b within drug-solid/lipid nanoparticle formulation prepared by hot melting homogenization technique and evaluated for encapsulation efficiency, particle size, and zeta potential. Significant improvement was seen at the compound’s cytotoxic activity. In conclusion, 8b is introduced as a promising anti-cancer lead candidate that worth future fine-tuned lead optimization and development studies while exploring its potentiality through in-vivo preclinical investigation.

    癌症是一种多因素疾病,需要确定新的治疗靶点。抑制Bcl-2以触发促凋亡信号被认为是癌症治疗的一种有前途的策略。在当前工作中,我们旨在设计和合成一系列新的苯并咪唑吲哚生物,作为Bcl-2蛋白的抑制剂。市场上的全Bcl-2抑制剂obatoclax是采用结构修饰的主要框架化合物。将obatoclax的吡咯甲亚甲基连接物替换为直链烷胺或羧酰亚甲基连接物,提供了新的化合物。这种策略允许合成化合物的结构灵活性得到改善,采用有利的操作方式更好地适配Bcl-2的主要疏口袋。通过MTT细胞毒性分析、细胞周期分析、RT-PCR、ELISA和DNA断裂进一步研究了合成化合物的抗癌活性。细胞毒性结果显示,化合物8a、8b和8c对MDA-MB-231/乳腺癌细胞表现出有希望的细胞毒性(IC50 = 12.69 ± 0.84至12.83 ± 3.50 µM),而8a和8c对A549/肺腺癌细胞显示出明显的活性(IC50 = 23.05 ± 1.45和11.63 ± 2.57 µM,分别)。通过分子对接确认了Bcl-2抑制途径,显示了显著的对接能量和与关键Bcl-2口袋残基的相互作用。此外,最活性的化合物8b通过RT-PCR分析显示了促凋亡/抗凋亡基因Bax、Bcl-2、caspase-3、-8和-9的显著上调表达平。通过引入8b到热熔均质化技术制备的药物固体/脂质纳米粒子配方进行了化合物的药理学特性改进,并评估了包封效率、粒径和Zeta电位。化合物的细胞毒性活性得到了显著改善。总之,8b被引入为有前途的抗癌首选候选化合物,值得在未来的精细化首选优化和开发研究中进行探索,同时通过体内临床前研究探讨其潜力。
