Isoxazole analogs of curcuminoids with highly potent multidrug-resistant antimycobacterial activity

Curcumin (1), demethoxycurcumin (2) and bisdemethoxycurcumin (3), the curcuminoid constituents of the medicinal plant Curcuma longa L, have been structurally modified to 55 analogs and antimycobacterial activity against Mycobacterium tuberculosis has been evaluated. Among the highly active curcuminoids, the isoxazole analogs are the most active group, with mono-O-methylcurcumin isoxazole (53) being the most active compound (MIC 0.09 mu g/mL). It was 1131-fold more active than curcumin (1), the parent compound, and was approximately 18 and 2-fold more active than the standard drugs kanamycin and isoniazid, respectively. Compound 53 also exhibited high activity against the multidrug-resistant M. tuberculosis clinical Isolates, with the MICs of 0 195-3.125 mu g/mL. The structural requirements for a curcuminoid analog to exhibit antimycobacterial activity are the presence of an isoxazole ring and two unsaturated bonds on the heptyl chain. The presence of a suitable para-alkoxyl group on the aromatic ring which is attached in close proximity to the nitrogen function of the isoxazole ring and a free para-hydroxyl group on another aromatic ring enhances the biological activity.

Recent progresses in the synthesis of functionalized isoxazoles

Isoxazole is an important pharmacophore that is critical for biological activity. The isoxazole ring ranks 33rd in frequency among the 351 ring systems found in marketed drugs, thus suggesting a great deal of interest in the synthesis of functional isoxazoles. In recent years, various approaches have been developed for the synthesis and functionalization of isoxazoles. This comprehensive survey summarizes the recent new synthetic approaches to functionalized isoxazoles, with particular focus on the last three years with regard to the following reaction types: (1) 1,3-dipolar cycloaddition, (2) condensation, (3) cycloisomerization, and (4) direct functionalization.

Isoxazole mediated synthesis of 4-(1H)pyridones: improved preparation of antimalarial candidate GSK932121

A new synthesis of the antimalarial clinical candidate GSK932121 is described. This approach has two key reactions, the selective acylation of an unprotected 3-hydroxymethyl-5-methyl isoxazole and the reductive N-O bond cleavage of the previously functionalized isoxazole derivative, to give the 4-(1H)pyridone ring present in the final structure. The complete synthesis consists of 5 steps (versus 10 steps in previously published reports) and has enabled the preparation of the material in kilogram scale to support clinical studies.
