Several classes of prochiral dihalides have been identified as potential candidates for asymmetric halogen-lithium exchange. Bis-aryl compounds 1 and 2, 2,3-dibromonorbornadiene 3, and 1,2-diiodoferrocene 4 were prepared and used as substrates in the asymmetric halogen-lithium exchange reaction. The enantioselective mono-lithiation was achieved in good yields by various combinations of n-BuLi and chiral ligands. Enantioselectivities in the range of 20-35% ee have been detected for this new type of asymmetric synthesis. The prochiral compounds 3 and 4 were also dissolved in a chiral liquid crystal based on organic solutions of poly-gamma-benzyl-l-glutamate and analyzed using natural abundance deuterium 2D NMR spectroscopy. The spectroscopic discrimination of enantiotopic sites in these solutes has been observed and discussed from the point of view of orientational order.

The synthesis of the marine neurotoxin azaspiracid-1 has been accomplished. The individual fragments were synthesized by catalytic enantioselective processes: A hetero-Diels-Alder reaction to afford the E- and HI-ring fragments, a carbonyl-ene reaction to furnish the CD-ring fragment, and a Mukaiyama aldol reaction to deliver the FG-ring fragment. The subsequent fragment couplings were accomplished by aldol and sulfone anion methodologies. All ketalization events to form the nonacyclic target were accomplished under equilibrating conditions utilizing the imbedded configurations of the molecule to adopt one favored conformation. A final fragment coupling of the anomeric EFGHI-sulfone anion to the ABCD-aldehyde completed the convergent synthesis of (+)-azaspiracid-1.

11beta-Hydroxysteroid dehydrogenase type 1 (11beta-HSD1) has been widely considered by the pharmaceutical industry as a target to treat metabolic syndrome in type II diabetics. We hypothesized that central nervous system (CNS) penetration might be required to see efficacy. Starting from a previously reported pyrimidine compound, we removed hydrogen-bond donors to yield 3, which had modest CNS penetration. More significant progress was achieved by changing the core to give 40, which combines good potency and CNS penetration. Compound 40 was dosed to diet-induced obese (DIO) mice and gave excellent target engagement in the liver and high free exposures of drug, both peripherally and in the CNS. However, no body weight reduction or effects on glucose or insulin were observed in this model. Similar data were obtained with a structurally diverse thiazole compound 51. This work casts doubt on the hypothesis that localized tissue modulation of 11beta-HSD1 activity alleviates metabolic syndrome.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 87392-05-0, and how the biochemistry of the body works.Related Products of 87392-05-0

Proteasome inhibition has been validated as a therapeutic modality in the treatment of multiple myeloma and Non-Hodgkin’s lymphoma. Carfilzomib, an epoxyketone currently undergoing clinical trials in malignant diseases, is a highly selective inhibitor of the chymotrypsin-like (CT-L) activity of the proteasome. A chemistry effort was initiated to discover orally bioavailable analogues of carfilzomib, which would have potential for improved dosing flexibility and patient convenience over intravenously administered agents. The lead compound, 2-Me-5-thiazole-Ser(OMe)-Ser(OMe)-Phe-ketoepoxide (58) (PR-047), selectively inhibited CT-L activity of both the constitutive proteasome (beta5) and immunoproteasome (LMP7) and demonstrated an absolute bioavailability of up to 39% in rodents and dogs. It was well tolerated with repeated oral administration at doses resulting in >proteasome inhibition in most tissues and elicited an antitumor response equivalent to intravenously administered carfilzomib in multiple human tumor xenograft and mouse syngeneic models. The favorable pharmacologic profile supports its further development for the treatment of malignant diseases.
