The synthesis and in vitro structure-activity relationships (SAR) of a series of triazoles as A(2A) receptorantagonists is reported. This resulted in the identification of potent, selective and permeable 1,2,4-triazoles such as 42 for further optimization and evaluation in vivo.

The present invention relates to a novel heteroaryl compound, an enantiomer, a diastereomer or a pharmaceutically acceptable salt thereof, and an antiviral composition comprising the same as an active ingredient. The novel compounds represented by formula (I) or formula (II) according to the present invention are remarkably superior in antiviral activity against an influenza virus, and furthermore, have low cytotoxicity and thus low adverse effects on a human body. Therefore, a pharmaceutical composition containing the same as an active ingredient can be effectively used for the prevention or treatment of diseases caused by an influenza virus infection.

Somatostatin receptor-4 (SST4) is highly expressed in brain regions affiliated with learning and memory. SST4 agonist treatment may act to mitigate Alzheimer's disease (AD) pathology. An integrated approach to SST4 agonist lead optimization is presented herein. High affinity and selective agonists with biological efficacy were identified through iterative cycles of a structure-based design strategy
