Synthesis and in vitro Anti‐Mycobacterium Activity of N‐Alkyl‐1,2‐dihydro‐2‐thioxo‐3‐pyridinecarbothioamides. Preliminary Toxicity and Pharmacokinetic Evaluation.

Disseminated infections with Mycobacterium tuberculosis (MT) and Mycobacterium avium complex (MAC) are increasingly opportunistic diseases in patients with advanced acquired human immunodeficiency syndrome (AIDS). A series of N-alkyl-1,2-dihydro-2-thioxo-3-pyridinecarbothioamides has been synthesized, and MICs for MT and MAC strains, either standard or isolated from infected patients, have been determined. Preliminary tests show a good activity and a very low toxicity for some derivatives. Pharmacokinetic studies in the rat show a very rapid elimination from the body after intravenous administration and a poor absorption after oral administration.
