Pulmonary fibrosis is a life threating disease which requires an immediate treatment and due to the limited medications, this study focused on synthesizing a series of quinoline-based pyrimidodiazepines as a novel antifibrotic hit. The target compounds were synthesized via a one-pot reaction then investigated in a rat model of lung fibrosis induced by bleomycin (BLM). Results revealed significant attenuation of the tested pro-inflammatory cytokines, fibrotic genes and apoptotic markers; however, Bcl-2 was upregulated, indicating a protective effect against fibrosis. Moreover, the molecular docking studies highlighted promising interactions between compounds and and specific amino acids within the protein pockets of caspase-3 (ARG341 and THR177), malondialdehyde (LYS195, LYS118 and ARG188) and TNF-α (SER99 and NME102). Compounds and emerge as promising candidates for further preclinical investigation as pulmonary antifibrotic agents.
肺纤维化是一种危及生命的疾病，需要立即治疗，并且由于可用药物有限，本研究专注于合成一系列基于喹啉的嘧啶二氮䓬类化合物作为新型抗纤维化先导化合物。目标化合物通过一锅法反应合成，然后在博来霉素（BLM）诱导的大鼠肺纤维化模型中进行研究。结果显示，所测试的促炎细胞因子、纤维化基因和凋亡标志物显著减少；然而，Bcl-2上调，表明对纤维化具有保护作用。此外，分子对接研究突出了化合物与半胱天冬酶-3（ARG341和THR177）、丙二醛（LYS195、LYS118和ARG188）以及肿瘤坏死因子-α（SER99和NME102）蛋白口袋内特定氨基酸之间有前景的相互作用。化合物和作为肺抗纤维化药物进一步临床前研究的有前景的候选物而出现。
