Abstract: A library of 19 novel 4-(4-phenylpiperazine-1-yl)benzamidines has been synthesized and evaluated in vitro against Pneumocystis carinii. Among these compounds, N-ethyl and Nhexyl 4-(4-phenylpiperazine-1-yl)benzamidines emerged as the most promising compounds with inhibition percentages at 0.1μg/ml of 61(percent) and 56(percent) respectively.
