Hydroflumethiazide-13C-d2 is intended for use as an internal standard for the quantification of hydroflumethiazide (Item No. 23612) by GC- or LC-MS. Hydroflumethiazide is a thiazide diuretic and an inhibitor of carbonic anhydrase (CA).{23242} It is selective for CAII, CAVB, CAVII, CAIX, CAXII, and CAXIV (Kis = 0.24-0.31 µM) over CAI, CAIV, and CAVI (Kis = 2.8-8.3 µM), as well as CAIII, CAVA, and CAXIII (Kis = >10 µM). Formulations containing hydroflumethiazide have been used in the treatment of hypertension.

Cyclin-dependent kinases (CDKs) are key regulators of cell cycle progression and are therefore promising targets for cancer therapy. (R)-Roscovitine is a potent inhibitor of Cdk2/cyclin E with an IC50 value of 0.1 µM.{14988} It also inhibits Cdk7/cyclin H, Cdk5/p35, and cell division cycle (cdc)/cyclin B with IC50 values of 0.49, 0.16, and 0.65 µM, respectively.{14987,14988,14991} (R)-Roscovitine inhibits the growth of rapidly proliferating cells with an average IC50 value of 15.2 µM against a panel of 19 human tumor cell lines.{14988} In murine models of polycystic kidney disease, (R)-roscovitine effectively inhibited disease progression at doses of 50-100 mg/kg.{14564}

The nuclear factor-κB (NF-κB) regulates the expression of numerous genes involved in immunity and inflammation, cellular stress responses, growth, and apoptosis. Resveratrol, a polyphenolic trans-stilbene, is a known inhibitor of the activation of NF-κB and exhibits activity against a wide variety of cancer cells. CAY10512 is a substituted trans-stilbene analog of resveratrol that is 100-fold more potent as measured by antioxidant activity. The IC50 value for inhibition of TNFα-induced activation of NF-κB by CAY10512 is 0.15 µM compared to 20 µM by resveratrol.{14545}
