The asymmetric total synthesis of the strongly cytotoxic phenanthroindolizidine alkaloid 3 was achieved. Using the same route, various derivatives were also synthesized. Cytotoxicity of those synthetic compounds was evaluated and compounds 19, 23, and 27 demonstrated potent cytotoxicities similar to that of 3. The in vivo antitumor efficacy of selected compounds was also evaluated and 23 demonstrated moderate antitumor efficacy. (C) 2010 Elsevier Ltd. All rights reserved.

A method of isolating at least one phenanthroindolizidine alkaloid, in particular with HIF-1 inhibitory activity, from
Tylophora atrofolliculata
is used to isolate and obtain for example about 22 phenanthroindolizidine alkaloids, including at least 11 new phenanthroindolizidine alkaloids which have not been previously isolated. Experimental tests confirmed an exceptional HIF-1 inhibitory activity of the phenanthroindolizidine alkaloids isolated. A pharmaceutical composition includes at least one phenanthroindolizidine alkaloid and at least one pharmaceutical tolerable excipient. A method of treating a subject suffering from cancer includes administering at least one phenanthroindolizidine alkaloid isolated from
Tylophora atrofolliculata
. A method of treating a subject suffering from cancer includes administering at least one phenanthroindolizidine alkaloid to the subject.
