5, 8, 9, 12, 13, and 15-strong class="EmphasisTypeBold">17) were synthesized and evaluated for their ability to inhibit the in vitro aggregation by washed human platelets induced by adenosine 5-diphosphate (10?μM). The antiplatelet activity of dl-n-butyl 5-hydroxy-N-(2-phenoxypropionyl)anthranilate (9, IC50?=?10.5?μM) was most active among the tested compounds and ethyl ester 8 (IC50?=?11.2?μM) showed the second most activity. dl-Ethyl and dl-n-butyl 5-(p-toluenesulfonyloxy)-N-(2-phenoxypropionyl)anthranilate (12, IC50?=?13.1?μM and 13, IC50?=?14.0?μM), dl-methyl N-(2-phenoxybutyryl)anthranilate (2, IC50?=?12.7?μM), dl-N-(2-phenoxypropionyl)anthranilic acid (5, IC50?=?13.7?μM) displayed lower antiplatelet activity than 8 and 9. Compound 5 was more active than methyl ester prodrug 1. n-Butyl 5-hydroxy-N-(4-acetoxybenzoyl)anthranilate (15, IC50?=?28.3?μM) showed moderate activity. Compounds 1 (IC50?=?42.8?μM), 4 (IC50?=?56.7?μM), 16 (IC50?=?51.0?μM), and 17 (IC50?=?49.8?μM) exhibited low antiplatelet activity. Methyl N-phenoxyacetylanthranilate (3, IC50?=?78.0?μM) showed the lowest antiplatelet activity. The compounds with branched alkyl chain (2 and 5) were more active than compounds with straight chain (3 and 4). The apparent permeability coefficient (Papp, cm/s) values of compounds 2 and 9 were determined as 45.34?±?4.67 and 33.17?±?5.15?×?10??cm/s by Caco-2 cell permeability assay." />
