A series of tetrahydro-β-carbolines and 1,3,5-triazine hybrids have been synthesized and evaluated for their cytotoxicity against a panel of eight human cancer cell lines and normal human fibroblasts (NIH3T3). It led us to discovery of racemic compounds 69, 71 and 75, which are selectively cytotoxic towards KB (oral cancer) cell line with IC50 values of 105.8, 664.7 and 122.2?nM, respectively; while their enantiopure forms are less active and not selective. Enantiopure compound 42 showed 2.5 times more selectivity towards MCF7 cells over normal fibroblast NIH3T3 cells with an IC50 value of 740?nM, also arrests cell cycle in G1 phase and induces apoptosis in MCF7 and MDA MB231cell lines.

A mild and efficient protocol for the Pictet-Spengler reaction in water using an acid catalyst has been described. The condensation of tryptophan, tryptamine, and Nb-benzyl tryptophan with different aldehydes having both electron-withdrawing and -donating substituents in the presence of a catalytic amount of TFA in water furnished tetrahydro-β-carbolines in good isolated yields. A salient feature of the water mediated Pictet-Spengler reaction was the general trend observed during the condensation of Trp-OMe and aryl/aliphatic aldehydes furnishing diastereomeric mixtures with a preference for the cis-isomer.
