What is S(+)-N,N-DIETHYL-N'([8ALPHA]-6-METHYLERGOLIN-8-YL)UREA?

Description

Terguride (37686-84-3) is a semi-synthetic ergoline derivative which acts as a partial dopamine D2 agonist and 5HT2B/2C receptor antagonist. Displays antiparkinsonian effects in MPTP-treated cynomolgus monkeys.1?Partial agonist at recruitment of β-arrestin2 to the D2 receptor.2 Terguride ameliorates monocrotaline-induced pulmonary hypertension in rats.3
