Development of novel vitamin D receptor-coactivator inhibitors

Nuclear receptor coregulators are master regulators of transcription and selectively interact with the vitamin D receptor (VDR) to modulate cell differentiation, cell proliferation, and calcium homeostasis. Herein, we report the syntheses and evaluation of highly potent and selective VDR-coactivator inhibitors based on a recently identified 3-indolylmethanamine scaffold. The most active compound, PS121912, selectively inhibited VDR-mediated transcription among eight other nuclear receptors tested. PS121912 is also selectively disrupting the binding between VDR and the third nuclear receptor interaction domain of the coactivator SRC2. Genetic studies revealed that PS121912 behaves like a VDR antagonist by repressing 1,25-(OH)2D3 activated gene transcription. In addition, PS121912 induced apoptosis in HL-60.

Direct C-H carboxylation with carbon dioxide using 1,2,3-triazol-5-ylidene copper(I) complexes

1,2,3-Triazol-5-ylidene copper(I) complexes (tzNHC-Cu) efficiently catalyzed the direct C-H carboxylation of benzoxazole and benzothiazole derivatives with CO2 to give the corresponding esters in excellent yields after treatment with alkyl iodide. The tzNHC copper(I) complex, i.e., [(TPr)CuCl], worked somewhat more effectively than the corresponding imidazol-2-ylidene copper(I) complex [(IPr)CuCl] to give the carboxylation product in higher yields.

Substituted 2-benzothiazolamines as sodium flux inhibitors: Quantitative structure-activity relationships and anticonvulsant activity

Thirty-two aryl-substituted 2-benzothiazolamines have been tested for their ability to modulate sodium flux in rat cortical slices. A QSAR analysis, applied to these derivatives, showed a trend toward increasing potency as sodium flux inhibitors with increasing lipophilicity, decreasing size, and increasing electron withdrawal of the benzo ring substitutents. Additionally, 4- or 5-substitution of the benzo ring was found to decrease potency. The combination of increased lipophilicity, small size, and electron withdrawal severely limited which groups were tolerated on the benzo ring, thus suggesting that the optimal substitution patterns have been prepared within this series. Nine of these compounds were potent inhibitors of veratridine-induced sodium flux (NaFl). These nine compounds also proved to be anticonvulsant in the maximal electroshock (MES) assay. Fourteen additional 2-benzothiazolamines demonstrated activity in the MES screen, yet exhibited no activity in the NaFl assay. These derivatives may be interacting at the sodium channel in a manner not discernible by the flux paradigm, or they may be acting by an alternative mechanism in vivo.

On the persistence of mouse urine odour to human observers: a review

To the human nose, mice produce unique, persistent and potent odour which is widely assumed to be derived mainly from their urine. In this review, we discuss why the mouse odour is so potent and long-lasting to the human nose. Sensory and chemical analyses have revealed that 2-sec-butyl-4,5-dihydrothiazole (SBT) was the major mousy odorant and present almost exclusively in male urine. It is not depleted from urine even after repeated headspace or solvent extractions since its majority is tightly bound to the major urinary proteins (MUPs) in male mouse urine that serve to control the release. The urinary concentration of SBT is estimated to be around several hundred parts per million when the binding of SBT to MUPs is considered, while its human olfactory threshold is estimated to be approximately at the parts per billion level. Therefore, the strikingly persistent quality of mouse urine odour, mainly contributed by SBT, is explained by its low human olfactory threshold, its presence in urine at a high concentration, and its delayed release by MUPs.

Copper-promoted sandmeyer difluoromethylthiolation of aryl and heteroaryl diazonium salts

An efficient copper-promoted difluoromethylthiolation of aryl and heteroaryl diazonium salts is described. The reaction is conducted under mild reaction conditions and various functional groups were compatible. In addition, reactions of heteroaryl diazonium salts such as pyridyl, quinolinyl, benzothiazolyl, thiophenyl, carbazolyl, and pyrazolyl diazonium salts occurred smoothly to afford the medicinally important difluoromethylthiolated heteroarenes. Furthermore, a more practical one-pot direct diazotization and difluoromethylthiolation protocol was developed, and it converts the aniline derivatives into difluoromethylthiolated arenes. The utility of the method is demonstrated by difluoromethylthiolation of a number of natural products and drug molecules. A dose of salt: The title reaction is conducted under mild reaction conditions and various functional groups are compatible. (Hetero)aryl diazonium salts reacted smoothly to afford the medicinally important difluoromethylthiolated (hetero)arenes. A practical one-pot direct diazotization and difluoromethylthiolation protocol was developed for aniline derivatives to generate difluoromethylthiolated arenes.
