TH-162, also known as (R)-PIA and Adenosine, N-(1-methyl-2-phenylethyl)-, (R)-, is an agonist of the A1 adenosine receptor. Affinity for adenosine receptors is approx. 100× that of the (+)-isomer.
Selective antagonist of α6-containing nicotinic receptors that discriminates between the closely related α6 and α3 subunits (IC50 values are 0.95 and 74.2 nM for rat α6 α3β2β3 and α3β2 receptors respectively).
Epianhydrotetracycline (EATC) is a degradation product of the antibiotic tetracycline .1 EATC is active against Pseudomonas, Agrobacterium, Moraxella, Bacillus, and E. coli (MIC50s = 0.75-16 mg/L).
L-Sepiapterin, also known as Sepiapterin, is a precursor compound crucial for the production of tetrahydrobiopterin (BH4), which serves as a coenzyme for endothelial nitric oxide synthase (eNOS). This compound demonstrates its efficacy by improving endothelial dysfunction in small mesenteric arteries from db db mice and promoting angiogenesis. Moreover, L-Sepiapterin exerts inhibitory effects on cellular proliferation and migration in ovarian cancer cells through the down-regulation of p70S6K-dependent vascular endothelial growth factor receptor-2 (VEGFR-2) expression[1][2].
