The acyl-enzyme formed upon acylation of alpha-chymotrypsin with isatoic anhydride has been characterised by infrared spectroscopy. Acylation at pH 7 to yield the 2-aminobenzoyl-enzyme is rapid (k = 5.57x 10(-2)s(-1)), while deacylation is much slower (k =3.7 x 10(-5)10(-2) (s-).

The biosynthesis and modulation of the vasoconstrictor peptide endothelin was studied in the conditioned medium from cultured bovine pulmonary artery endothelial (BPAE) cells. Conditioned medium from cultured BPAE cells produced contraction of isolated rabbit aortic rings. Incubation of BPAE cells

A one-pot cascade reaction has been developed leading to the concurrent construction of six and five membered fused N-heterocyclic rings of indazolo[3,2-b]quinazolinones. The methodology involved the reaction of isatoic anhydride, a hydrazine and o-iodo benzaldehyde in the presence of Pd(PPh(3))(4)

A fluorescent tRNA derivative labeled at 3'-O position of the ultimate adenosine residue by reaction, under mild conditions, of tRNA with isatoic anhydride [3,1-benzoxazine-2,4(1H)-dione] was obtained. The labeling selectivity was determined by several criteria: digestion with RNase, followed by HPLC

A nonstabilized azomethine ylide reacts with a wide range of substituted isatoic anhydrides to afford novel 1,3-benzodiazepin-5-one derivatives, which are generally isolated in high yield. The transformations involve 1,3-dipolar cycloaddition reactions of the ylide with the anhydrides to give transient
