, p. 1949 - 1956 (2017/05/29)
Tumor angiogenesis has become an important target for antitumor therapy, with most current therapies aimed at blocking the vascular endothelial growth factor (VEGF) pathway. The VEGF and its receptors have been implicated as key factors in tumor angiogenesis and are major targets in cancer therapy. A series of aryl-modified benzoylamino-N-(5,6-dimethoxy-1H-benzoimidazol-2-yl)-heteroamides were synthesized from 2-amino-5,6-dimethoxy benzimidazole and aryl-substituted benzoylamino hetero acids. The new compounds were tested for inhibition of VEGF receptors I and II (VEGFR-1 and VEGFR-2). Compound 6e displayed VEGFR-2 inhibitory activity with a 50% inhibition concentration value as low as 0.020 μM in a homogeneous time-resolved fluorescence enzymatic assay. VEGFR-2 active compounds display good activity against VEGFR-1 as well.
Azaindole synthesis through dual activation catalysis with N-heterocyclic carbenes
Sharma, Hayden A.,Todd Hovey,Scheidt, Karl A.
supporting information, p. 9283 - 9286 (2016/07/25)
A convergent, transition-metal-free synthesis of 2-aryl-azaindoles has been developed. The interception of a reactive aza-ortho-azaquinone methide intermediate by an acyl anion equivalent generated through carbene catalysis provides high yields, a wide substrate scope, and the synthesis of previously inaccessible azaindoles.

Nicotinic acid adenine dinucleotide phosphate analogues containing substituted nicotinic acid: Effect of modification on Ca2+ release
Jain, Pooja,Slama, James T.,Perez-Haddock, Leroy A.,Walseth, Timothy F.
experimental part, p. 7599 - 7612 (2011/02/22)
Analogues of nicotinic acid adenine dinucleotide phosphate (NAADP) with substitution at either the 4- or the 5-position position of the nicotinic acid moiety have been synthesized from NADP enzymatically using Aplysia californica ADP-ribosyl cyclase or mammalian NAD glycohydrolase. Substitution at the 4-position of the nicotinic acid resulted in the loss of agonist potency for release of Ca2+-ions from sea urchin egg homogenates and in potency for competition ligand binding assays using [32P]NAADP. In contrast, several 5-substituted NAADP derivatives showed high potency for binding and full agonist activity for Ca2+ release. 5-Azido-NAADP was shown to release calcium from sea urchin egg homogenates at low concentration and to compete with [32P]NAADP in a competition ligand binding assay with an IC50 of 18 nM, indicating that this compound might be a potential photoprobe useful for specific labeling and identification of the NAADP receptor.
