Storage: 2 years -80°C in solvent; 3 years -20°C powder; H2O 50 mg/mL (104.81 mM) Solubility DMSO 31 mg/mL (64.98 mM) ( < 1 mg/ml refers to the product slightly soluble or insoluble ) Calcium channel blocker;P- glycoprotein (P-gp) inhibitor Receptor (IC50) Calcium channel blocker P-gp (P-glycoprotein) In vitro Activity Norverapamil also inhibits macrophage-induced tolerance and achieves similar serum levels to verapamil. Verapamil and its major metabolite Norverapamil were identified to be both mechanism-based inhibitors and substrates of CYP3A and reported to have non-linear pharmacokinetics in the clinic. Norverapamil hydrochloride ((±)-Norverapamil hydrochloride) is similarly effective as verapamil at inhibiting isoniazid and rifampicin tolerance and killing of intracellular M. tuberculosis in the absence of other drugs [1][3]. In vivo Activity Norverapamil hydrochloride (9 mg/kg; p.o.) has a terminal half-life, AUC and Cmax values of 9.4 hours, 260 ng▪h/ml, and 41.6 ng/mL, respectively[4]. Reference 1. Adams KN, et al.

  • Screening of Pharmaceuticals in San Francisco Bay Wastewater
    Screening of Pharmaceuticals in San Francisco Bay Wastewater Prepared by Diana Lin Rebecca Sutton Jennifer Sun John Ross San Francisco Estuary Institute CONTRIBUTION NO. 910 / October 2018 Pharmaceuticals in Wastewater Technical Report Executive Summary Previous studies have shown that pharmaceuticals are widely detected in San Francisco Bay, and some compounds occasionally approach levels of concern for wildlife. In 2016 and 2017, seven wastewater treatment facilities located throughout the Bay Area voluntarily collected wastewater samples and funded analyses for 104 pharmaceutical compounds. This dataset represents the most comprehensive analysis of pharmaceuticals in wastewater to date in this region. On behalf of the Regional Monitoring Program for Water Quality in San Francisco Bay (RMP), the complete dataset was reviewed utilizing RMP quality assurance methods. An analysis of influent and effluent information is summarized in this report, and is intended to inform future monitoring recommendations for the Bay. Influent and effluent concentration ranges measured were generally within the same order of magnitude as other US studies, with a few exceptions for effluent. Effluent concentrations were generally significantly lower than influent concentrations, though estimated removal efficiency varied by pharmaceutical, and in some cases, by treatment type. These removal efficiencies were generally consistent with those reported in other studies in the US. Pharmaceuticals detected at the highest concentrations and with the highest frequencies in effluent were commonly used drugs, including treatments for diabetes and high blood pressure, antibiotics, diuretics, and anticonvulsants. For pharmaceuticals detected in discharged effluent, screening exercises were conducted to determine which might be appropriate candidates for further examination and potential monitoring in the Bay.

RMP 2015 THE PULSE OF THE BAY The State of Bay Water Quality: 2015 and 2065 A REPORT OF THE REGIONAL MONITORING PROGRAM FOR WATER QUALITY IN SAN FRANCISCO BAY Overview This edition of The Pulse of the Bay is a companion to the 2015 State of the Estuary Report. A water quality section of the State of the Estuary Report assesses our progress in meeting the Clean Water Act goals of waters that are swimmable, fishable, and safe for aquatic life. The Pulse provides a closer look at the state of San Francisco Bay water quality in 2015 and progress made since the State of the Bay Report in 2011. This Pulse also peers into the crystal ball at what the condition of Bay water might be 50 years from now. OVERVIEW 2 The Current State of Bay Water Quality Two important new initiatives that couple water quality management and monitoring have taken shape in the past On the good-fair-poor scale used in the State of the Estuary few years focused on nutrients and emerging contaminants.
