The purpose of this paper is to investigate the inhibition effect of some Chalcone derivatives on the corrosion behavior of aluminum in 1 M phosphoric acid solutions with and without Chalcone derivatives and to investigate the influence of halide additives namely: KCl, KBr and KI on the inhibition efficiency of aluminum. For this purpose, polarization (DC) and weight loss measurements were used...

objective(s):one strategy for the treatment of diabetes is inhibition of pancreatic α- amylase. plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. materials and methods: urtica dioica and juglans regia linn were tested for α-amylase inhibition. different concentrations of leaf aqueous extracts were incubated with enzym...

Previously we have already shown that tetrasulfonylamidinecalixarene C-90 inhibited plasma membrane ??2+,Mg2+-????se of smooth muscle cells selectively to other ATPases membrane. To inhance the inhibitory effect calixarenes several alkoxycalixarene sulfonylamidines structurally similar calixa­rene were synthesized and their effects on mentioned enzyme activity, level cytoplasmic Ca2+ concentrat...
