Abstract:
Two series of 6-pyridazinone derivatives (17-30) were synthesized and evaluated for antitubercular activities against the Mycobacterium tuberculosis H37Rv strain. The results indicated that among the synthesized compounds, 5-( 4-hydroxy-3-methoxybenzyl}-3-phenyl-1,6-dihydro-6-pyridazinone (23) showed good antitubercular activity. Three more compounds, (18, 25 & 27) were significant in their antitubercular action. The present study reveals the antitubercular potential of 6-pyridazinones.

Objective: Pyrazolines are known to exhibit different biological and pharmacological properties such as anticancer, antibacterial, antifungal and antitubercular activities. Chalcones with an enone group between two aromatic rings exhibit remarkable pharmacological activities such as antiinflammatory, antibacterial, antitumor, antifungal, and antimalarial activity. A series of pyrazolines from chalcones have been synthesized and evaluated for antitubercular and cytotoxic activity studies.Methods: Chalcones [3-substituted phenyl-1-(p-tolyl)prop-2-en-1-one] were synthesized from various substitut

Now treatment of chalcones with hydrazine hydrate/glacial acetic acid and guanidine hydrochloride/Alkali afforded the corresponding acetyl pyrazoline (E1-E5) and amino pyrimidine (F1-F5) derivatives respec

Abstract:
This review contains a compendium of medicinal plants in Africa that can control or cure tuberculosis. A good number of plant secondary metabolites are reported to have antitubercular activity comparable to the existing antitubercular drugs or sometimes even better. Information regarding the chemistry and pharmacology of plants leads to insight into their structure–activity relationship and potency. A well-defined strategy is required to exploit these phytomolecules as antitubercular drugs.

Tuberculosis is a leading cause of mortality and morbidity worldwide, claiming 1.2 million deaths (including 208 000 people with HIV) and 10 million new cases in 2019. Current treatment suffers from significant shortcomings such as length, dosage regimen, toxicity, and resistance development to currently used medicines. The emergence of multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis is a major concern in controlling the disease. Therefore, there is an urgent need for new antitubercular drugs that are active against resistant strains, less toxic, and that act upon
