Zusammenfassung
Me2NCH2C(C6H4R-p):C(C6H4R-p)Et [I, R = H (II) or OMe (III)] were prepd. by reaction of Me2NCH2CH(C6H4R-p)COC6H4R-p with EtMgBr and dehydration of the resulting alc. with PCl3. Ether cleavage of III with AlBr3 in C6H6 gave I [R = OH (IV)]. II and IV had no estrogenic properties. II, III, and IV showed no antibacterial effects in vitro and only low activity against mouse sarcoma 180 and rat Yoshida ...

Ether cleavage of III with AlBr3 in C6H6 gave I [R = OH (IV)]. II and IV had no estrogenic properties. II, III, and IV showed no antibacterial effects in vitro and only low activity against mouse sarcoma 180 and rat Yoshida sarcoma in vivo. II caused good inhibition of rat mammary carcinoma. The i.p. LD50 values of II, III, and IV were 120, 160, and 150 mg/kg, resp., in rats.
