Partenogennetic activation of metaphase II oocytes treated by ferrocenyl 4-(alkylamino)-1,4-dihydroquinolines. Oocytes were incubated or not with compounds 8 or 11 before they were transfered to a 5×-diluted ND96 solution added with A23187 calcium ionophore (50 μM). The numbers of cortical retraction were scored. N refers to the number of females and n to the number of oocytes (N = 2 and n = 40).
