TL;DR: In this article, six new metabolites, including two diphenolic derivatives (1 and 2), one pseurotin (3), one butenolide derivative (4), one benzopyran (5) and one isochromane lactone (6), together with ten known compounds (7, 16) were isolated from an endophytic fungus Aspergillus sp.

TL;DR: In this article , photochromic spiropyrans (SPPs) with fluorine substituents and cationic fragments or formyl groups at positions 6′ and 8′ of the 2H-chromene moiety were synthesized using a simple one-pot method.

07 Jun 1995TL;DR: In this paper, the authors defined a class of compounds having the formula ##STR1## and pharmaceutically acceptable salts thereof wherein a, b and d are all carbon atoms or one of a,b and d is a nitrogen atom or --N(O)-- and the others are carbon atoms; Y is a single bond.
Abstract: Compounds having the formula ##STR1## and pharmaceutically acceptable salts thereof wherein a, b and d are all carbon atoms or one of a, b and d is a nitrogen atom or --N(O)-- and the others are carbon atoms; Y is a single bond, --CH 2 --, --C(O)--, --O--, --S-- or --N(R 8 )--; and R 1 to R 7 are as defined herein. These compounds have potassium channel activating activity and are useful, therefore for example, as cardiovascular agents.

TL;DR: In this paper, the authors showed that vasorelaxant activity is linearly correlated with the electronic parameter (σm) and parabolically correlated with steric (L) and hydrophobic (π) parameters of the 6-substituent benzopyran-4-carbothioamides.
