Catalytic alpha-Selective Deuteration of Styrene Derivatives

We report an operationally simple protocol for the catalytic alpha-deuteration of styrenes. This process proceeds via the base-catalyzed reversible addition of methanol to styrenes in DMSO-d6 solvent. The concentration of methanol is shown to be critical for high yields and selectivities over multiple competing side reactions. The synthetic utility of alpha-deuterated styrenes for accessing deuterium-labeled chiral benzylic stereocenters is demonstrated.

Experimental and computational studies on the formation of three para-benzyne analogues in the gas phase

Experimental and computational studies on the formation of three gaseous, positively-charged para-benzyne analogues in a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer are reported. The structures of the cations were examined by isolating them and allowing them to react with various neutral reagents whose reactions with aromatic carbon-centered sigma-type mono- and biradicals are well understood. Cleavage of two iodine-carbon bonds in N-deuterated 1,4-diiodoisoquinolinium cation by collision-activated dissociation (CAD) produced a long-lived cation that showed nonradical reactivity, which was unexpected for a para-benzyne. However, the reactivity closely resembles that of an isomeric enediyne, N-deuterated 2-ethynylbenzonitrilium cation. A theoretical study on possible rearrangement reactions occurring during CAD revealed that the cation formed upon the first iodine atom loss undergoes ring-opening before the second iodine atom loss to form an enediyne instead of a para-benzyne. Similar results were obtained for the 5,8-didehydroisoquinolinium cation and the 2,5-didehydropyridinium cation. The findings for the 5,8-didehydroisoquinolinium cation are in contradiction with an earlier report on this cation. The cation described in the literature was regenerated by using the literature method and demonstrated to be the isomeric 5,7-didehydro- isoquinolinium cation and not the expected 5,8-isomer. Pick the right isomer! The generation of three positively charged para-benzyne analogues was attempted in an FT-ICR mass spectrometer. The experimental and quantum chemical findings indicate that the monoradical precursors for the para-benzynes undergo ring-opening faster than formation of the para-benzyne by iodine atom elimination, thus generating enediyne isomers of the para-benzynes (see scheme).

Novel transient receptor potential vanilloid 1 receptor antagonists for the treatment of pain; Structure-activity relationships for ureas with quinoline, isoquinoline, quinazoline, phthalazine, quinoxaliue, and cinnoline moieties

Novel transient receptor potential vanilloid 1 (TRPV1) receptor antagonists with various bicyclic heteroaromatic pharmacophores were synthesized, and their in vitro activity in blocking capsaicin activation of TRPV1 was assessed. On the basis of the contribution of these pharmacophores to the in vitro potency, they were ranked in the order of 5-isoquinoline > 8-quinoline = 8-quinazoline > 8-isoquinoline ? cinnoline ? phthalazine ? quinoxaline ? 5-quinoline. The 5-isoquinoline-containing compound 14a (hTRPV1 IC50 = 4 nM) exhibited 46% oral bioavailability and in vivo activity in animal models of visceral and inflammatory pain. Pharmacokinetic and pharmacological properties of 14a are substantial improvements over the profile of the high-throughput screening hit 1 (hTRPV1 IC50 = 22 nM), which was not efficacious in animal pain models and was not orally bioavailable.

Synthesis and study of substituted amides of isoquinoline-3- and isoquinoline-1-carboxylic acids as potential anticonvulsants

Previously obtained benzylamides of isoquinoline-3-carboxylic acids and isoquinoline-1-carboxylic acids exhibited anticonvulsant activity. In search for more effective anticonvulsants, a series of amides of isoquinoline-3- and isoquinoline-1-carboxylic acids have been synthesized (1-9). The obtained compounds were evaluated qualitatively for their anticonvulsant activity in the maximal electroshock seizure test (MES test), minimal clonic seizure test (6Hz test) and subcutaneous metrazol seizure threshold test (sc MET test) as well as in the rotorod neurotoxicity test (Tox test). One selected compound was tested quantitatively in 6Hz-test in mice after intraperitoneal administration and showed activity ED50 = 385.69 mg/kg and TD50 > 600 mg/kg (1).

Identification of New FLT3 Inhibitors That Potently Inhibit AML Cell Lines via an Azo Click-It/Staple-It Approach

Acute myeloid leukemia (AML) is an aggressive malignancy with only a handful of therapeutic options. About 30% of AML patients harbor mutated FLT3 kinase, and thus, this cancer-driver has become a hotly pursued AML target. Herein we report a new class of FLT3 inhibitors, which potently inhibit the proliferation of acute myeloid leukemia (AML) cells at nanomolar concentrations.
