The cholinergic pathways in the central nervous system (CNS) of animals and humans are important for cognitive and behavioural functions. Until a few years ago, it was thought that the key molecules transducing the cholinergic message were the metabotropic muscarinic receptors, but it is now known that ionotropic neuronal nicotinic receptors (nAChRs) are also involved. Based on recent studies, we prepared a small library of novel 3-substituted-3,6-diazabicyclo [3.1.1]heptanes, whose binding activity and functionality have been assayed. Among the synthesized compounds, the 3-(anilino)pyridine series resulted in the most interesting compounds with alpha4beta2 Ki values ranging from 0.0225 nM (12g) to 2.06 nM (12o).

A readily available and inexpensive natural alpha -amino acid is converted into a compound represented by formula (1), which is then reacted with an organometallic reagent represented by formula (2) to give an optically active 5-hydroxyoxazolidine represented by formula (3), which is then treated with an acid to provide an optically active aminoketone represented by formula (4). The product is then converted into an optically active aminoalcohol represented by formula (5) or (6) by, for example reduction.The above process can provide an optically active aminoalcohol represented by formula (5) or (6) useful as a production intermediate for a medicine or pesticide from a readily available and inexpensive natural alpha-amino acid as a starting material stereoselectively and stably with a higher optical purity and a lower cost without racemization.

A complementary and general strategy for the oxidative generation of iminyl radicals from the readily available alpha-imino-oxy acids has been established through silver-catalyzed decarboxylation. To demonstrate its synthesis utility, the direct C-H cyanoalkylation of heterocycles and quinones with cyclic alpha-imino-oxy acids via the iminyl radical-mediated C-C bond cleavage is developed. This cost-effective method takes place under mild reaction conditions and exhibits a broad substrate scope.

In a Article，once mentioned of 932-22-9

Our previous work on pyridazinone-arylpiperazine derivatives suggested some structural features that a compound should have to show high affinity and good selectivity for alpha(1) adrenoceptors (AR) with respect to alpha(2)-AR. Accordingly, two classes of new alkoxyphenylpiperazinylheptylpyridazinones were designed and synthesized to evaluate the effect of the alkoxy substituent on affinity and selectivity. As expected, affinity increased with larger alkoxy groups. Affinity values are all comparable with that of the reference compound (prazosin), with the exception of compound 1c found 4.5-fold more active than prazosin.

Tumors have evolved a variety of methods to reprogram conventional metabolic pathways to favor their own nutritional needs, including glutaminolysis, the first step of which is the hydrolysis of glutamine to glutamate by the amidohydrolase glutaminase 1 (GLS1). A GLS1 inhibitor could potentially target certain cancers by blocking the tumor cell’s ability to produce glutamine-derived nutrients. Starting from the known GLS1 inhibitor bis-2-(5-phenylacetamido-1,2,4-thiadiazol-2-yl)ethyl sulfide, we describe the medicinal chemistry evolution of a series from lipophilic inhibitors with suboptimal physicochemical and pharmacokinetic properties to cell potent examples with reduced molecular weight and lipophilicity, leading to compounds with greatly improved oral exposure that demonstrate in vivo target engagement accompanied by activity in relevant disease models.
