The reactions of the dithiolato-o-carborane salt (Et3NH)2(S2C2B10H10) (2) with alkyl halides BrCH2CH=CH2, BrCH2CH2CH2Cl and C6H5CH2Cl, afford the o-carboranyl-bisthioether derivatives 3a – c, which have been characterized by IR and NMR (1H, 13C, 11B) spectroscopy, mass spectrometry, and single-crystal X-ray diffraction (3c). The photoluminescent properties of the known compound 3c has been inve...
Bupropion is widely used for treatment of depression and as a smoking-cessation drug. Despite more than 20 years of therapeutic use, its metabolism is not fully understood. While CYP2B6 is known to form hydroxybupropion, the enzyme(s) generating erythroand threohydrobupropion have long remained unclear. Previous experiments using microsomal preparations and the nonspecific inhibitor glycyrrheti...
The involvement of protein kinase CK1δ in the pathogenesis of severe disorders such as Alzheimer's disease, amyotrophic lateral sclerosis, familial advanced sleep phase syndrome, and cancer has dramatically increased interest in the development of effective small molecule inhibitors for both therapeutic application and basic research. Unfortunately, the design of CK1 isoform-specific compounds ...
A substantial amount of evidence has proposed an important role for Cyclooxygenase-2 (COX-2) enzyme in brain diseases and affiliate disorders. The purpose of this research was studying the effects of COX-2 selective inhibition on haloperidol-induced catatonia in an animal model of drug overdose and Parkinson's disease (PD). In this study, the effect of acute and Sub-chronic oral administration ...
Adrenocorticosteroid activity in Lyon hypertensive (LH) and low blood pressure (LL) rat strains differ in several respects. Abnormal activity of 11b-hydroxysteroid dehydrogenase enzymes (11b-HSD1 and 11b-HSD2), which interconvert corticosterone and inactive 11-dehydrocorticosterone, might contribute to the LH phenotype by regulating corticosteroid hormone access to receptors. 11b-HSD2 (expresse...
Background: During human pregnancy, 11b-hydroxysteroid dehydrogenase type 2 (11b-HSD2) plays an important role in protecting the fetus from high maternal glucocorticoid concentrations by converting cortisol to inactive cortisone. Furthermore, 11b-HSD2 is indirectly involved in the regulation of the prostaglandin inactivating enzyme 15-hydroxyprostaglandin dehydrogenase (PGDH), because cortisol ...
The title compound C14H12BF9O2 (1) was obtained as the sole product during a failed attempt to make new organoboron compound. Characterization of by NMR (1H, 13C{1H}, 19F{1H}, and 11B) spectroscopy single crystal X-ray diffractometry confirmed formation 1. Compound 1 crystallizes in triclinic space group P-1, with = 8.275(5) Å, b 8.611(5) c 10.910(5) α 89.634(5)°, β 89.637(5)°, γ 87.403(5)°, V ...
11b-Hydroxysteroid dehydrogenase type 1 (11b-HSD1) locally regenerates active glucocorticoids from their inert forms thereby amplifying intracellular levels within target tissues including the brain. We previously showed greater increases in intra-hippocampal corticosterone (CORT) levels upon Y-maze testing in aged wild-type than in 11b-HSD1 / mice coinciding with impaired and intact spatial me...
Polyomaviruses such as BK virus and JC virus have been linked to several diseases, but treatments that thwart their propagation are limited in part because of slow growth and cumbersome culturing conditions. In contrast, the replication of one member of this family, Simian Virus 40 (SV40), is robust and has been well-characterized. SV40 replication requires two domains within the viral-encoded ...
Placental 11b-hydroxysteroid dehydrogenase (11b-HSD) regulates transplacental passage of maternal glucocorticoids to the fetus and is thus a key determinant of fetal glucocorticoid levels. It has also been proposed that placental 11b-HSD expression may influence local glucocorticoid actions by regulating access of corticosterone to the glucocorticoid receptor (GR) or mineralocorticoid receptor ...
