In an systematic attempt to develop novel Selective Estrogen Receptor Modulators (SERMs), chiral 1-((4-(2-(dialkylamino)ethoxy)phenyl)(2- hydroxynaphthalen-1-yl)methyl)piperidin-4-ols were designed based on an accepted pharmacophore model. Simpler prototypes, viz. racemic 1-((2-hydroxynaphthalen- 1-yl)arylmethyl)piperidin-4-ols, were first synthesized to develop kinetic resolution to pure enantiomers. Simultaneously, a series of racemic 1-((4-(2-(dialkylamino)ethoxy)phenyl)(2-hydroxynaphthalen-1-yl)methyl) piperidin-4-ols were evaluated against estrogen-responsive human MCF-7 breast cancer cells, but the compounds were found to be moderately active. The lack of potency could be due to the molecular bulk resulting in inadequate fit at the receptor. Subsequently, the molecular motif was modified to achiral 1-(4-(2-(dialkylamino)ethoxy)benzyl)naphthalen-2-ols by removing the piperidinol moiety. Bioevaluation of this new series of compounds displayed significantly enhanced cytotoxicity against MCF-7 cells. A representative compound for this series showed estrogen receptor alpha binding activity and the action is that of an antagonist.

A series of [4-(aryloxy)phenyl]cyclopropyl methanones were synthesized by reaction of different benzyl alcohols with 4-chloro-4′-fluorobutyrophenone in DMF in the presence of NaH/TBAB. The methanones were further reduced to respective methanols. The antitubercular activity of these compounds was evaluated in vitro against Mycobacterium tuberculosis H37Rv. Compounds 19, 21, 35, 36 and 37 have shown minimum inhibitory concentration (MIC) of 3.12 μg/mL, while compounds 14, 25 and 18 have shown MIC of 1.56 μg/mL and 0.78 μg/mL respectively. One of the compounds, cyclopropyl-4-[4-(2-piperidin-1- yl-ethoxy)benzyloxy]phenyl}methanol (36) showed 98% killing of intracellular bacilli in mouse bone marrow derived macrophages and was active against MDR, XDR and rifampicin clinical isolates resistant strains with MIC 12.5 μg/mL. Compound 36 was orally active in vivo in mice against M. tuberculosis H37Rv with an increase in MST by 6 days with 1 log reduction in the bacillary density in lungs as compared to control on 30th day after infection.
