21414781-2	2011	In general, reported CRF(1) receptor antagonists possess a sp(2)-nitrogen atom as hydrogen bonding acceptor (HBA) on their core scaffolds.	sp(2)	59-64	corticotropin releasing hormone receptor 1	Mus musculus	21-36	
21414781-3	2011	We proposed to use a carbonyl group of pyrrolo[2,3-d]pyrimidin-4-one derivatives as a replacement for the sp(2)-nitrogen atom as HBA in classical CRF(1) receptor antagonists.	sp(2)	106-111	corticotropin releasing hormone receptor 1	Mus musculus	146-161
