[[https://www.uniprot.org/uniprot/LEB_MACLB LEB_MACLB]] Lebetins inhibit platelet aggregation induced by thrombin, collagen and PAF-acether. Human platelet aggregation induced by thrombin is inhibited by synthetic lebetin-1-alpha, lebetin-1-beta, lebetin-1-gamma, lebetin-2-alpha and lebetin-2-beta with IC(50) values of 140, 32, 5, 2.5 and 2.8 nM, respectively. Lebetins also inhibit fibrinogen-induced aggregation of alpha-chymotrypsin-treated platelets as well as in vivo collagen-induced thrombocytopenia in rats. Lebetins are not toxic upon intravenous injection into mice and rats.<ref>PMID:11910186</ref> <ref>PMID:8769304</ref> <ref>PMID:9839678</ref>
