Antimycobacterial activity of methdilazine (Md), an antimicrobic phenothiazine

Abstract
Methdilazine (Md) could inhibit various Mycobacterium spp. at 5-15 micrograms/ml concentrations in vitro as well as in vivo. When Md was tested in combination with streptomycin (Sm), rifampicin (Rf) or methyl-DOPA (m-D), it showed synergistic effects only with respect to methyl-DOPA.
