Synthetic Studies of Indoles and Related Compounds. XXVIII. Intramolecular Vinylation of Pyrrole Derivatives Using Palladium: a New Synthetic Method for Substituted Indoles.
An object of the present invention is to provide a drug having the inhibitory activity on ENPP2 which is a different target from that of the existing drug, as a medicament useful in a urinary excretion disorder patient for whom the existing drug has the insufficient effect.
The present invention provides a compound represented by the general formula (I):
(wherein definition of each group is as defined in the description) having the ENPP2 inhibitory activity, a salt thereof or a solvate thereof or a prodrug thereof, and an agent for preventing or treating urinary excretion disorder and/or improving symptoms thereof, containing them as an active ingredient.

the hydrolysis of substrates containing both saturated and α,β-unsaturated/cyclopropanecarboxylic esters (methyl and ethyl), was studied. An exclusive hydrolysis of the saturated esters was observed. Kinetic experiments revealed that the presence of deactivated carbonyl in the unsaturated/cyclopropanecarboxylic esters and their weaker bindings are both responsible for the observed specificity. The
Scarce and precious: A collection of compounds with deep‐seated structural “point mutations” within the framework of the marine natural products amphidinolideX and Y was prepared by “diverted total synthesis”. The resulting products provided first insights into the cytotoxicity profile of these extremely scarce macrolides.
