LY2334737 is an nucleoside analog and is an orally active prodrug of Gemcitabine. LY2334737 exhibits inhibitory activity against enterovirus A71 (EV-A71) infection. LY2334737 has antiviral and anticancer effects^[1][2].

Enterovirus A71 (EV-A71)^[2]

Five cell lines that express CES2 responded to LY2334737 treatment. LY2334737 is less cytotoxic to a SK-OV-3 CES2 knockdown than parental cells. The drug response of CES2-transfected HCT-116 cells correlated with CES2 expression level. Bystander studies show statistically greater PC-3-GFP growth inhibition by LY2334737 when cells are cocultured with CES2 and not mock transfectants^[1].

Oral treatment of xenograft models with 3.2 mg/kg LY2334737 once a day for 21 days shows greater tumor growth inhibition of CES2 transfectant than the mock transfectant^[1].
Metronomic LY2334737 administration causes increased blood flow in luciferase-tagged LM2-4 tumor xenografts, and this effect, readily measured using contrast micro-ultrasound, coincided with a relative increase in tumor bioluminescence^[3].
