2-Hydroxy-4-n-5-bromoacetophenone oxime (HnPBAO) was developed as a new analytical reagent for the gravimetric determination of divalent palladium ion. In the pH range of 2.0 to 5.0, the reagent gave a light brown precipitate with Pd(II). Job’s method and mole ratio method revealed that the stoichiometry of the complex is 1:2 (metal : ligand). Beer’s law is obeyed upto 37.25 ppm of Pd(II) at 45...

Male and female F344 rats but not B6C3F1 mice exposed for 104 weeks to propiverine hydrochloride (1-methylpiperid-4-yl 2,2-diphenyl-2-(1-propoxy)acetate hydrochloride), used for treatment of patients with neurogenic detrusor overactivity (NDO) and overactive bladder (OAB), presented with an accumulation of proteins in the cytosol and nuclei of renal proximal tubule epithelial cells, yet despite...

A computational analysis of the molecular ordering of the non-liquid crystalline biphenyl derivative 4,4′-diamino-3,3′-dimethylbiphenyl (DADMBP) has been performed. The CNDO/2 method has been employed to compute the net atomic charge and atomic dipole components at each atomic centre. The modified Rayleigh-Schrödinger perturbation theory along with the multicentered-multipole expansion method h...

We tested several histamine H(1) receptor (H(1)R) and antagonists for their differences in agonists binding affinities between human and guinea pig H(1)Rs transiently expressed in African green monkey kidney (COS-7) cells. Especially, the bivalent agonist histaprodifen-histamine dimer (HP-HA) shows a higher affinity for guinea pig than for human H(1)Rs. Based on the structure of HP-HA, we have ...
