Results 2 ClAdo and 2 CldAdo had different cytotoxicities on the cells, while 2' dAdo had no cytotoxicity on the cells. 2 CldAdo blocked the cell growth at the phase of S and G2/M, while 2 ClAdo at the phase of G0/G1. 2 CldAdo mainly induced cell necrosis, while 2 ClAdo induced both cell necrosis and apoptosis.
