BICYCLIC COMPOUNDS FOR DIAGNOSIS AND THERAPY

The present invention relates to the compounds of formula (I) that can be employed in the diagnosis, monitoring of disease progression or monitoring of drug activity, of a group of disorders and abnormalities associated with alpha-synuclein (a-synuclein, A- synuciein, aSynuciein, A-syn, a-syn, aSyn) aggregates including, but not limited to, Lewy bodies and/or Lewy neurites, such as Parkinson’s disease. The instant compounds are particularly useful in determining a predisposition to such a disorder, monitoring residual disorder, or predicting the responsiveness of a patient who is suffering from such a disorder to the treatment with a certain medicament. The present compounds can also be used to treat, alleviate or prevent a disorder or abnormality associated with alpha-synuclein aggregates.

1,2-Benzothiazine 1,1-dioxide P2-P3 peptide mimetic aldehyde calpain I inhibitors

A series of peptide mimetic aldehyde inhibitors of calpain I was prepared in which the P2 and P3 amino acids were replaced by substituted 3,4-dihydro-1,2-benzothiazine-3-carboxylate 1,1-dioxides. The effect of 2, 6, and 7-benzothiazine substituents and the P1 amino acid was examined. Potency of these inhibitors, 15c-p, against human recombinant calpain I is particularly dependent upon the 2-substituent, with methyl and ethyl generally more potent than hydrogen, isopropyl, isobutyl, or benzyl. The more potent diastereomer of 15m possesses the (S) absolute configuration at the 3-position of the 3,4-dihydro-l,2-benzothiazine. Potency of the best inhibitors in this series (IC50=5-7 nM) compares favorably with that of conventional N-benzyloxycarbonyl dipeptide aldehyde inhibitors bearing L-Leu or L-Val residues at P2. The achiral unsaturated 1,2-benzothiazine analogues 26a-d are also potent calpain I inhibitors, while 3,4-dihydro-2,1-benzoxathiin (15a,b), 1,2,4-benzothiadiazine (32a,b), and tetrahydroisoquinolinone (36a,b) analogues are less potent.

Synthesis and biological activity of novel carbacyclins having bicyclic substituents on the omega-chain

A number of carbacyclins having bicyclic substituents on the omega-chain have been synthesized and tested for antiplatelet aggregation activity in vitro (against collagen-induced aggregation of rat platelet), for reduction of systemic blood pressure in vivo (ability to reduce the blood pressure in anesthetized rat by iv injection), and for cytoprotective activity (protection against ethanol-induced rat gastric lesion). The most effective compound for each activity was [3aS-[2E,3aalpha,4alpha(3R),5beta,6aalpha]]-5-[hexahydro-5-hydroxy-4-[3-hydroxy-3-(2- indanyl)-1-propynyl]-2(1H)-pentalenylidene]pentanoic acid (compound 11a), while some 1,4-benzodioxan analogues had selectivity for organ-protective activity, and indan analogues showed selectivity in their antiaggregation activity.

Decarboxylative Giese-Type Reaction of Carboxylic Acids Promoted by Visible Light: A Sustainable and Photoredox-Neutral Protocol

We describe herein a transition-metal-free method for the decarboxylative generation of radicals from carboxylic acids and their 1,4-addition to Michael acceptors. The Fukuzumi catalyst (9-mesitylene-10-methylacridinium perchlorate, [Acr-Mes]ClO4) enabled this transformation under visible-light irradiation at room temperature with CO2 as the only byproduct. The scope and limitations of this protocol were examined by using a range of Michael acceptors (15 examples) and carboxylic acids (18 examples). The use of 3-hydroxypivalic acid in this protocol allowed the straightforward formation of a diastereomerically pure delta-lactone. Moreover, when a homoallylic acid was used, a radical cascade reaction took place with the formation of three C?C bonds.

Nonheme iron-mediated amination of C(sp3)-H bonds. Quinquepyridine-supported iron-imide/nitrene intermediates by experimental studies and DFT calculations

The 7-coordinate complex [Fe(qpy)(MeCN)2](ClO4) 2 (1, qpy = 2,2?:6?,2?:6?, 2???:6???,2????- quinquepyridine) is a highly active nonheme iron catalyst for intra- and intermolecular amination of C(sp3)-H bonds. This complex effectively catalyzes the amination of limiting amounts of not only benzylic and allylic C(sp3)-H bonds of hydrocarbons but also the C(sp3)-H bonds of cyclic alkanes and cycloalkane/linear alkane moieties in sulfamate esters, such as those derived from menthane and steroids cholane and androstane, using PhI=NR or “PhI(OAc)2 + H2NR” [R = Ts (p-toluenesulfonyl), Ns (p-nitrobenzenesulfonyl)] as nitrogen source, with the amination products isolated in up to 93% yield. Iron imide/nitrene intermediates [Fe(qpy)(NR)(X)]n+ (CX, X = NR, solvent, or anion) are proposed in these amination reactions on the basis of experimental studies including ESI-MS analysis, crossover experiments, Hammett plots, and correlation with C-H bond dissociation energies and with support by DFT calculations. Species consistent with the formulations of [Fe(qpy)(NTs)2] 2+ (CNTs) and [Fe(qpy)(NTs)]2+ (C) were detected by high-resolution ESI-MS analysis of the reaction mixture of 1 with PhI=NTs (4 equiv). DFT calculations revealed that the reaction barriers for H-atom abstraction of cyclohexane by the ground state of 7-coordinate C NTs and ground state of C are 15.3 and 14.2 kcal/mol, respectively, in line with the observed high activity of 1 in catalyzing the C-H amination of alkanes under mild conditions.
