Importantly, the modes of action of recognized Pks13 inhibitors differ from traditional anti-TB medications, highlighting Pks13 as a potential and promising target in drug development within TB treatment. In this study, we discovered a compound named BMVC-8C3O that effectively inhibited the activity of Pks13 with a 6.94 μM IC₅₀ value. The binding between BMVC-8C3O and Pks13 was validated through surface plasmon resonance (SPR) assay as well as molecular docking analysis. Moreover, the SPR assay showed that the mutation of Asn1640 and Ser1533 resulted in decreased affinity of BMVC-8C3O to Pks13. Additionally, BMVC-8C3O not only exhibited activity against <em>Mycobacterium tuberculosis</em> (MTB), but also displayed potential intracellular anti-TB activity in macrophages.

TB usually affects the lungs, in 25 % of patients (children or immune impaired adults), mycobacteria can enter the blood stream and infect other bodily areas such the meninges, pleura, lymphatic system, genitourinary system, bones, and joints. Currently, the most challenging aspect of treating this illness is the ineffectiveness of the most potent first-line anti-TB medications, isoniazid, rifampin, pyrazinamide, and ethambutol, which can result in multidrug-resistant TB (MDR-TB), extensively drug-resistant TB (XDR-TB), and in rare instances, completely drug-resistant TB (TDR-TB). As a result, finding new pharmaceutical compounds to treat these diseases is a significant challenge for the scientific community. A number of bio-active molecules have been investigated in this quest, including quinoline, which is considered a promising candidate for the development of TB drugs. It is known that quinoline are low in toxicity and have a wide range of pharmacological properties. Researchers have investigated quinoline scaffolds as anti-TB drugs based on their biological spectrum. The objective of this review is to examine the recent development of quinoline and its structural characteristics crucial to its antitubercular (anti-TB) activity.
