Leishmaniasis is a neglected tropical disease, affecting more than 350 million people globally. However, there currently no vaccine available against human leishmaniasis, and current treatment hampered by high cost, side-effects, painful administration routes. It has become United Nations goal to end leishmaniasis epidemics 2030, multitarget drug strategy emerges as promising alternative. Among the compounds, flavonoids are renowned class of natural products, structurally diverse library can be prepared through organic synthesis, which tested for biological effectiveness. In this study, we synthesised 17 flavonoid analogues using scalable, easy-to-reproduce, inexpensive method. All compounds presented an impressive inhibition capacity rCPB2.8, rCPB3, rH84Y enzymes, highly expressed in amastigote stage, target form parasite. Compounds 3c, f12a, f12b were found effective all isoforms. Furthermore, their intermolecular interactions also investigated molecular modelling study. These potent parasite demonstrated low cytotoxic action mammalian cells. results pioneering, representing advance investigation mechanisms behind antileishmanial derivatives. Moreover, have been shown leads design other cysteine protease inhibitors diseases.

Background:: The escalation of cancer worldwide is one the major causes economy burden and loss human resources. According to American Cancer Society, there will be 1,958,310 new cases 609,820 projected deaths in 2023 United States. It that by 2040, global expected rise 29.5 million per year, causing a death toll 16.4 million. hemostasis regulation cellular protein synthesis their targeted degradation required for normal cell growth. imbalance unbridled growth cells results cancer. DNA needs chemotherapeutic agents treatment, but at same time, efficacy toxicity also need considered successful treatment. Objective:: objective this study review published work on pyrrole pyridine, which have been prominent diagnosis possess anticancer activity, obtain some novel lead molecules improved therapeutic. Methods:: A literature search was carried out using different engines, like Sci-finder, Elsevier, ScienceDirect, RSC etc., small based pyridine helpful inducing apoptosis cells. research findings application these compounds from 2018-2023 were reviewed variety lines, such as breast cancer, liver epithelial etc. Results:: In review, molecules, derivatives, roles treatment cancers, discussed provide insight into structural features responsible analogues with chromeno-furo-pyridine skeleton showed highest activity against compound 5-amino-N-(1-(pyridin-4- yl)ethylidene)-1H-pyrazole-4-carbohydrazides highly potent HEPG2 cell. Redaporfin used cholangiocarcinoma, biliary tract cisplatin-resistant head neck squamous carcinoma, pigmentation melanoma, it clinical trials phase II. These present high potential designing drug development. Conclusion:: Therefore, N- C-substituted pyridine-based privileged Nheterocyclic scaffolds are This discusses reports during 2018-2023. mainly various diagnostic techniques employ heterocyclic scaffolds. Furthermore, has described, works MCF-7, A549, A2780, HepG2, MDA-MB-231, K562, HT- 29, Caco-2 cells, Hela, Huh-7, WSU-DLCL2, HCT-116, HBL-100, H23, HCC827, SKOV3, help researchers critical aspects useful well design pathways develop drugs future.
