A convenient liquid chromatographic-single Quadrupole mass spectrometric (LC-MS) method was developed and validated for dexchlorpheniramine maleate (INN name: chlorphenamine) determination in human plasma. The need for just a single liquid-liquid extraction with ethyl acetate and being highly sensitive were the advantages of this method. The linearity was also excellent over the range of 1...

Maleate injection causes dose-dependent injury in proximal tubular cells. This study sought to better define underlying pathogenic mechanisms and to test whether maleate toxicity recapitulates critical components of the hypoxic/ischemic renal injury cascade. CD-1 mice were injected with maleate or used as a source for proximal tubule segments (PTS) for in vitro studies. Maleate induced dose-dep...

Timolol maleate has a molecular weight of 432.50. It is a white, odorless, crystalline powder which is soluble in water, methanol, and alcohol. Timolol maleate is stable at room temperature. Timolol maleate ophthalmic solution is supplied in two formulations: Ophthalmic Solution TIMOPTIC* (timolol maleate ophthalmic solution), which contains the preservative benzalkonium chloride; and Ophthalmi...

The growth of Pseudomonas fluorescens (ATCC 11150) on sodium maleate was observed, and the composition of the media was monitored in batch culture. Utilization of the maleate as the sole organic carbon source proceeded by stepwise conversion to fumarate and then to malate. Respiration rates of P. fluorescens on maleate, mixtures of maleate and fumarate salts, and mixtures of maleate and malate ...
