Tirandamycins from Streptomyces sp. 17944 inhibiting the parasite Brugia malayi asparagine tRNA synthetase.


ABSTRACT: Lymphatic filariasis is caused by the parasitic nematodes Brugia malayi and Wuchereria bancrofti, and asparaginyl-tRNA synthetase (AsnRS) is considered an excellent antifilarial target. The discovery of three new tirandamycins (TAMs), TAM E (1), F (2), and G (3), along with TAM A (4) and B (5), from Streptomyces sp. 17944 was reported. Remarkably, 5 selectively inhibits the B. malayi AsnRS and efficiently kills the adult B. malayi parasite, representing a new lead scaffold to discover and develop antifilarial drugs.
