title: A study on ester thiosemicarbazones.
abstract: The cyclization of ester thiosemicarbazones to two different heterocycles was studied for some new thiosemicarbazones, and only the formation of 1,2,4-triazol-5-thiols was attributed to the regioselectivity of the ring closure reaction, due to a steric hindrance of bulky groups. Next, some of the new compounds were tested for their in vitro antimicrobial and antitumor activities.
