Four unreported pyridine alkaloids, curviflorines A-D (1-4), two undescribed iridoids, curviridoids A and B (5 & 6), and one known iridoid glycoside (7), were isolated from the twigs and leaves of Phlogacanthus curviflorus. The structures of these compounds were established by detailed interpretation of MS and NMR data, with the absolute configurations being assigned via comparison of experimental and calculated electronic circular dichroism spectra. Notably, it is the first report of alkaloidal constituents (1-4) from the genus Phlogacanthus.

This study aimed to screen native methionine gamma-lyase (L-methioninase) producing bacteria from soil samples and optimize the culture media for enhanced enzyme production using statistical design. Three bacteria, were identified as novel L-methioninase producers, which alternative source of L-methioninase for cancer treatment could be utilized alongside other therapeutic agents. The bacteria were isolated from various garden soils and cultured on a modified M9 medium and screened by Nessler reagent.
