A phosphonic acid appended naphthalene diimide motif for self-assembly into tunable nanostructures through molecular recognition with arginine in water.

A naphthalene diimide motif bearing phosphonic acid functionalities has been found to be self-assembled with L- and D-arginine through chirality induced molecular recognitions and leads to the formation of micrometre long nanobelts and spherical aggregates at pH 9 in water, respectively.

Synthesis, crystal structure and antidiabetic activity of substituted (E)-3-(Benzo [d]thiazol-2-ylamino) phenylprop-2-en-1-one.

A novel series of substituted (E)-3-(Benzo [d]thiazol-2-ylamino)phenylprop-2-en-1-onewere synthesized starting from 2-aminobenzothiazole and 1-aryl-3,3-bis- (methylsulfanyl)-2-propen-1-onesin the presence of a catalytic amount of sodium hydride in THF. The synthesised compounds' structures were confirmed by IR, Mass spectrometry, (1)H NMR, (13)C NMR and HRMS spectral data. These compounds were evaluated for their antidiabetic activity, and most of the derivatives of (E)-3-(Benzo [d]thiazol-2-ylamino)phenylprop-2-en-1-one displayed significant antidiabetic activity.

Synthesis and glycosidase inhibitory activity of novel (2-phenyl-4H-benzopyrimedo[2,1-b]-thiazol-4-yliden)acetonitrile derivatives.

A series of (2-phenyl-4H-benzopyrimodo[2,1-b][1,3]thiazol-4-yliden-4-yliden)acetonitrile derivatives have been prepared by ring transformation reaction of 4-(methylthio)-2-oxo-6-aryl-2H-pyrane-3-carbonitriles. The yield of ring transformation product is moderate to good. Furthermore the glycosidase inhibitory activities were tested by using α-amylase and α-glucosidase pancreatic, intestinal and liver enzymes, responsible for hyperglycemia in type II diabetes.
