sought to identify a preclinical candidate with no asymmetry in rat brain penetration and that could advance into development. Merging the medicinal chemistry strategies of structure-baseddesign with parallelchemistry, a novel series of PDE9A inhibitors was identified that showed improved selectivity over PDE1C. Optimization afforded preclinical candidate 19 that demonstrated free brain/free plasma

The invention is to provide a novel anticancer agent or sensitizer for cancer chemotherapy or radiotherapy. A compound of a general formula (I): wherein A means an aryl group or a heteroaryl group, or a group of a formula (a):; R1 means a -(C=O)aOb(C1-C6)alkyl group, a -(C=O)aOb(C2-C6)alkenyl group, a -(C=O)aOb(C3-C6)cycloalkyl group, an aryl group or a heteroaryl group; R2 and R3 each mean a hydrogen atom, a halogen atom, a hydroxyl group, a carboxyl group, a -(C=O)aOb(C1-C6)alkyl group or a group of -(C=O)aN(R1e)R2e; R4 means a hydrogen atom or a (C1-C6)alkyl group, and the like have an excellent Wee1-kinase-inhibitory effect, and are therefore useful in the field of medicine, especially in the field of various cancer treatments.
A compound of formula (I), or a pharmaceutical salt thereof.

The present disclosure relates to HIF-2α inhibitors and methods of making and using them for treating cancer. Certain compounds were potent in HIF-2α scintillation proximity assay, luciferase assay, and VEGF ELISA assay, and led to tumor size reduction and regression in 786-O xenograft bearing mice in vivo.
The invention provides PDE9-inhibiting compounds of Formula (I),
and pharmaceutically acceptable salts thereof, wherein R
