Treatment of tuberculosis (TB) is a challenge because of multidrug-resistant and extremely drug-resistant strains of Mycobacterium tuberculosis. Plant species contain antimicrobial compounds that may lead to new anti-TB drugs. Previous screening of some tree species from the Anacardiaceae family revealed the presence of antimicrobial activity, justifying further investigations. Leaf extracts of...

Wollamide B is a cationic antimycobacterial cyclohexapeptide that exhibits activity against Mycobacterium bovis (M. bovis) (IC50 of 3.1 μM). Aiming to define its structural activity relationship (SAR), optimizing potency and pharmacokinetic properties, libraries of analogues were synthesized following a standard Fmoc-based solid phase peptide synthesis approach. The antimycobacterial activities...

Buruli ulcer (BU), caused by Mycobacterium ulcerans, has recently been recognized by the World Health Organization (WHO) as an important emerging disease. It is largely a problem of the poor in remote rural areas and has emerged as an important cause of human suffering. While antimycobacterial therapy is often effective for the earliest nodular or ulcerative lesions, for advanced ulcerated lesi...

Tuberculosis (TB) is an infectious disease caused by the bacterium, Mycobacterium tuberculosis (MTB). Uncontrolled usage of existing drugs the number of cases of tuberculosis throughout the world has been increasing rapidly, due to the emergence of Multi-drug resistant MTB strains, there is a need for new and novel sources of antimycobacterial drugs especially from the natural products. In this...

Benzoxazole nucleus is one of the most important heterocyclic compounds exhibiting remarkable pharmacological activities. The present review provides a broad overview of the synthesis and pharmacological activities such as antimycobacterial, anticonvulsant, anti-inflammatory, anticancer, DNA topoisomerase inhibitor, cholesterol ester transfer protein inhibitor and miscellaneous activities.

Bixa orellana is used in popular medicine against several diseases. Extracts of its fruit, root and leaf presented antimicrobial activity, while seed extract showed negative results. This study aimed at verifying the antimycobacterial activity of B. orellana lyophilized hydroalcoholic extracts over Mycobacterium tuberculosis, and determine the Minimum Inhibitory Concentration against five bacte...

Mycobacterium tuberculosis, the main cause of tuberculosis (TB), has still remained a global health crisis especially in developing countries. Tuberculosis treatment is a laborious and lengthy process with high risk of noncompliance, cytotoxicity adverse events and drug resistance in patient. Recently, there has been an alarming rise of drug resistant in TB. In this regard, it is an unmet need ...

Buruli ulcer (BU) imposes a serious economic burden on affected households and on health systems that are involved in diagnosing the disease and treating patients. Research is needed to find cost-effective therapies for this costly disease. Plants have always been an important source of new pharmacologically active molecules. Consequently we decided to undertake the study of plants used in trad...
