Anti-herpesvirus effects of Isoprinosine were found to be condition-dependent in vitro and in vivo. A herpes type 1 strain, grown in primary rabbit kidney cells, was not susceptible to Isoprinosine when cytopathic effect was evaluated, but was modestly inhibited when plaque-forming methocel overlay was used in the same cell line. However, the growth of a(More)
Amiprilose hydrochloride is a carbohydrate-derived, novel anti-inflammatory with potential application in the treatment of rheumatoid arthritis. A spectroscopy-based approach was undertaken to assign both the relative and absolute configuration of its five chiral centers. The fully assigned 13C and 1H NMR spectra of amiprilose hydrochloride was used to(More)
Apomorphine HCl is currently in phase III clinical trials for the treatment of erectile dysfunction. The potential for reproductive toxicity in males was assessed based on a 13-week rat study--a fertility study in male rats--and a 6-month study in dogs. The subcutaneous (s.c.) route was selected to simulate the sublingual route in humans. Dosages of(More)
Sorbitol and glycerol, along with other inactive ingredients such as preservatives and dyes, are commonly used in various pharmaceutical and personal care products. To accurately assess the effectiveness of various formulations containing sorbitol and/or glycerol, their quantitative determination is essential. In the current study, two types of detectors (a(More)
In the current study, injectable formulations containing Doxercalciferol as the active pharmaceutical ingredient are analyzed by using gradient-elution high-performance liquid chromatography with ultraviolet detection. Various related impurities and degradants are quantified by using solid-phase extraction (SPE) for enhanced sensitivity. The assay of(More)
