Pseudolaric acid-A and -B, the novel diterpene acids isolated from Pseudolarix kaempferi, and their related derivatives have been tested for cytotoxicity against KB, A-549, HCT-8, P-388, and L-1210 tumor cells. The results showed that pseudolaric acid-A and -B demonstrated potent cytotoxicity. The selectivity of pseudolaric acid-A and -B which inhibit the growth of particular cell types within the disease-oriented human cancer cell line panels is discussed.
