In vitro study | LY315920 significantly inhibited sPLA2 activity in serum of many different species, including Rat, rabbit, guinea pig and human, with IC50 of 8.1 nM, 5.0 nM, 3.2 nM and 6.2 nM, respectively. LY315920 acts on BAL cells lacking human sPLA2 in a dose range of 0.1 μm to 3 μm to reduce human sPLA2-regulated thrombosis in a concentration-dependent manner with an IC50 of about 0.8 μm. LY315920 (10 μm) significantly inhibited the expression of membrane-associated mucin MUC16 induced by all-trans-retinoic acid (RA) in Human conjunctival epithelial cell line (HCjE) by 100% at 24 hours, 99% inhibition at 48 hours. |
In vivo study | In vitro, LY315920 inhibits human sPLA2-induced thrombus release from Guinea pig BAL cells at doses of 3 mg/kg to 30 mg/kg I. V. The ED50 was 16.1 mg/kg. LY315920 was administered orally or intravenously at a dose of 0.3 mg/kg-3 mg/kg to abrogate serum sPLA2 activity in transgenic mice expressing human sPLA2 in a dose-and time-dependent manner. |

in vitro study | LY315920 acts on the serum of many different species, including rats, rabbits, guinea pigs and humans, significantly inhibiting sPLA2 activity, IC50 is 8.1 nM, 5.0 nM, 3.2 nM and 6.2 nM respectively. LY315920 acts on BAL cells lacking human sPLA2 in the dose range of 0.1 μM-3 μM to reduce thrombosis regulated by human sPLA2. This effect is concentration dependent, with IC50 of about 0.8 μM. LY315920 (10 μM) acts on human conjunctival epithelial cell line (HCjE) to significantly inhibit all-trans-retinoic acid (RA)-induced expression of membrane-associated mucin MUC16, inhibit 100% at 24 hours and inhibit 99% at 48 hours. |
in vivo study | in vitro, LY315920 treated by intravenous injection at a dose of 3 mg/kg to 30 mg/kg, inhibit the thrombus released from guinea pig BAL cells induced by human sPLA2. ED50 is 16.1 mg/kg. LY315920 treated transgenic mice expressing human sPLA2 at doses of 0.3 mg/kg-3 mg/kg orally or intravenously, serum sPLA2 activity was abolished. This effect was dose-and time-dependent. |
