This invention relates to certain heterocyclic compounds and their pharmaceutically acceptable salts, which are useful for sensitizing multidrug-resistant tumor cells to anticancer agents and multidrug resistant forms of malaria, tuberculosis, leishmania and amoebic dysentery to chemotherapeutants. The compounds and their pharmaceutically acceptable salts are also inhibitors of the active drug transport capability of P-glycoprotein which is encoded by the human MDR1 gene, as well as of certain other related ATP-binding-cassette transporters from eukaryotic and prokaryotic organisms (e.g., pfmdr from Plasmodium falciprum, and murine mdr1 and mdr3 gene products).

bromides and tosylates oxidatively rearrange in moist dimethyl sulphoxide to o-hydroxybenzyl esters; o-acetoxy- and o-benzoyloxy- phenacyl bromides rearrange to mixtures of 2-hydroxycoumaran-3-ones and o-hydroxyphenacyl esters; o-hydroxyphenacyl bromides also yield 2-hydroxycoumaran-3-ones, together with o-hydroxyphenacyl alcohols. 2-Acetoxybenzaldehyde is reductively rearranged by sodium borohydride to o-hydroxybenzyl
A series of 2-phenylimidazo[2,1-b]benzothiazole derivatives was prepared and tested for immunological activities. Some of the compounds showed significant suppressive activity of delayed type hypersensitivity (DTH) without inhibition of humoral immunity in mice by oral administration. The most active compound was 2-(m-hydroxyphenyl)imidazo[2,1-b]benzothiazole (20).
