Cardiovascular diseases are the most frequent cause of morbidity and mortality worldwide. In order to discover novel compounds with anti-platelet aggregation activities, a series of novel 4-methoxy-1,3-phthalamidesamides (1a–1i) and a series of novel 4-methoxy-1,3-benzenedisulfon-amides (2a–2i) were synthesized and their anti-platelet aggregation activities were evaluated by the turbidimetric method in response to the following agonists: adenosine diphosphate (ADP), arachidonic acid (AA), and Collagen. Those compounds that have better in vitro activities were subjected to cell toxicity tests via cell counting kit-8 (CCK-8) assay. The inhibition rates of anti-platelet in vitro of five compounds 1g (39.45%), 2d (38.87%), 2g (38.55%), 2h (44.56%), and 2i (43.93%) were higher than that of two reference drugs picotamide (36.12%) and aspirin (38.45%) when ADP was selected as an inducer. The inhibition rates of seven compounds 1c (43.63%), 1d (40.02%), 1g (47.42%), 1i (40.45%), 2c (40.11%), 2d (40.45%), and 2i (49.05%) were higher than that of picotamide (34.89%) and aspirin (39.43%) when AA was selected as inducer. And the inhibition rates of five compounds 1d (47.22%), 1i (45.01%), 2d (38.74%), 2e (42.21%), and 2f (39.94%) were higher than picotamide (38.45%) and aspirin (37.08%) when collagen was selected as inducer. Moreover, the effect of cell toxicity exhibited that none of the compounds had obvious cell toxicity against L-929 cells. Therefore, 4-methoxy-1,3-phthalamidesamides (1a–1i) and 4-methoxy-1,3-benzenedisulfon-amides (2a–2i) have the potential to become a novel kind of anti-platelet drugs and deserve further study.
