Plomestane (INNTooltip International Nonproprietary Name, USANTooltip United States Adopted Name; former developmental code name MDL-18962; also known as propargylestrenedione, PED) is a steroidal, irreversible aromatase inhibitor which was under development by Marion Merrell Dow/Hoechst Marion Russell (now Hoechst AG) as an antineoplastic agent for the treatment of breast cancer.[1][2][3][4][5] It was found to be effective in preclinical studies and was also found to produce few adverse effects in human clinical trials, significantly reducing estrogen levels with a single administration.[5] However, development of the drug for clinical use was halted due to "technical issues" and it was never marketed.[6]

In addition to its activity as an aromatase inhibitor, plomestane has weak androgenic properties.[5]

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
