Novel compounds belonging to the class of oxazolidinones possessing potent antimycobacterial properties especially useful in the treatment of acid fast organisms such as Mycobacterium tuberculosis, Mycobacterium avium-intracellular complex, M. fortuitum and M. kansai. The compound and its pharmaceutically acceptable salts thereof act as antibacterial agents. Also disclosed is a method for inhibiting growth of mycobacterial cells a well as a method of treating mycobacterial conditions such as Mycobacterium tuberculoses, drug resistant Mycobacterium tuberculosis, Mycobacterium avium-intracellular complex, M. fortuitum and M. kansai, comprising administering an antimycobacterially effective amount of the said compound and/or pharmaceutically acceptable salts thereof. There is also disclosed a process for the manufacture of the said compound or its pharmaceutically acceptable salts.
no-N-acetyltryptamine) have been synthesized and evaluated as melatonin receptor ligands. Introduction of a methoxycarbonylamino substituent at the C-7 position of the naphthalenic nucleus yields MT3 selective ligands. This selectivity can be modulated with suitable variations of the C-7 position and the acyl group on the C-1 side chain. We identified new series of compounds with affinity for the MT3
