Abstract

Aim: 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 4a-f as a novel antifibrotic hit.Materials & methods: The target compounds were synthesized via a one-pot reaction then investigated in a rat model of lung fibrosis induced by bleomycin (BLM).Results: 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 4b and 4c 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).Conclusion: Compounds 4b and 4c emerge as promising candidates for further preclinical investigation as pulmonary antifibrotic agents.

作为肺部抗纤维化药物的新型喹啉/嘧啶二氮杂卓的单锅合成和药理学评价。

目的：肺纤维化是一种威胁生命的疾病，需要立即治疗，由于药物有限，本研究重点合成了一系列喹啉基嘧啶二氮杂卓 4a-f 作为新型抗纤维化药物：通过一锅反应合成目标化合物，然后在博莱霉素（BLM）诱导的大鼠肺纤维化模型中进行研究：结果表明，受试的促炎细胞因子、纤维化基因和细胞凋亡标志物均明显减少；然而，Bcl-2上调，表明其具有抗纤维化的保护作用。此外，分子对接研究强调了化合物 4b 和 4c 与 Caspase-3（ARG341 和 THR177）、丙二醛（LYS195、LYS118 和 ARG188）和 TNF-α（SER99 和 NME102）蛋白质口袋中的特定氨基酸之间有希望的相互作用：结论：化合物 4b 和 4c 很有希望作为肺部抗纤维化制剂接受进一步的临床前研究。
