Microtubules play a dynamic role during cell division. In our early studies 4-phenyl-1-(1-acylindoline-5-sulfonylimidazolones were thoroughly explored and found that the indoline bicyclic system next to the sulfonyl group is very important for cytotoxicity. In this research, imidazolone motif was replaced with pyrrolidin-2-one and this isosteric replacement led to show some promising activity. Thus, the structure activity relationship of 4-phenyl-1-(1-acylindolin-5-ylsulfonyl)pyrrolidin-2-ones with the various acyl group at the indoline NH was explored. The presence of benzoyl groups with electron donating group was the more favorable for cytotoxicity while less bulky alkanoyl groups led to decrease cytotoxicity.

Abstract: Conjugates of hydroxy- and acetoxybenzoic acids with dipeptides based on 4-aminobutanoic acid and glycine were synthesized through hydroxy(acetoxy)benzoyl chlorides and 4-[hydroxy(acetoxy)benzoyl-amino]butanoyl chlorides as intermediate products. Acyl chlorides were prepared by treatment of the corre-sponding acids with oxalyl chloride in the presence of dimethylformamide at a ratio of 1:1.1:0.07 in boiling benzene. The target N-[hydroxy(acetoxy)benzoyl] derivatives of dipeptides were obtained with high yields, and no further purification of the products was necessary. The synthesized compounds were evaluated as potential neuroprotective agents.

Ten different acylamino-1,2,4-triazoles were prepared by the reaction of differently substituted benzoyl chlorides and acetyl chlorides with 4-amino-1,2,4-triazole using catalytic amount of triethylamine. The synthesized compounds were characterized using UV, 1H-nuclear magnetic resonance spectroscopy, and infrared spectroscopy. All the compounds were tested for their fungicidal potential against three fungal species, that is, Fusarium verticillioides, Macrophomina phaseolina, and Rhizoctonia solani using poisoned food technique. The synthesized compounds were tested at various concentrations along with standard carbendazim 50 WP. The amides synthesized by reaction of substituted benzoyl chlorides and 4-amino-1,2,4-triazole exhibited greater fungicidal activity against all the tested fungi as compared to the amides synthesized using substituted acetyl chlorides. Among all the tested compounds, 4-nitro-N-(4-H-1,2,4-triazol-4-yl)benzamide showed the maximum fungicidal activity with the least median effective dose (ED50) values of 100, 93, and 146 μg ml-1 against F verticillioides, M. phaseolina, and R. solani, respectively. All the compounds were found to be less effective than the standard used.
