Identifikohuni Regjistrohu
A series of enmein-type diterpenoid analogs (11-20) derived from natural kaurene-type diterpenoid oridonin were synthesized and biologically evaluated. All target compounds showed improved anti-proliferative activities against four human cancer cell lines compared with natural oridonin and parent

A series of enmein-type diterpenoid amino acid ester derivatives (14-22) were designed and synthesized according to l-alanine-(14-oridonin) ester trifluoroacetate (clinical candidate HAO472). Their antiproliferative activities were tested against SGC-7901, Bel-7402, HL-60, PC-3, A549 and K562 cancer
The conversion of oridonin to spirolactone-type or enmein-type diterpenoid: synthesis and biological evaluation of ent-6,7-seco-oridonin derivatives as novel potential anticancer agents.

Identifikohuni Regjistrohu
Starting from commercial available natural product oridonin (1), a practical synthesis of ent-6,7-seco-oridonin derivatives (2, 3, 5, and 9) was accomplished and their biological activities were evaluated. The conversion of spirolactone-type diterpenoid to enmein-type was first completed. The
Novel enmein-type diterpenoid hybrids coupled with nitrogen mustards: Synthesis of promising candidates for anticancer therapeutics.
