Synthesis and evaluation of an Iejimalide-archazolid chimera

Even though the macrolides of the iejimalide family are of marine origin, whereas those of the archazolid series derive from terrestrial myxobacteria, a comparison of their constitution, stereochemistry, and biological activity suggests that these natural products are close structural and functional relatives. Guided by this perception, compound 5 was prepared, which hybridizes the macrolactone core of iejimalide B (2) with the tail of archazolid A (3). The cytotoxicity profile of this chimera, as determined with a panel of 12 human cancer cell lines, corresponds to that of the parent compound 2, although its potency is lower. This outcome may be interpreted on the basis of molecular dynamics calculations, which suggest that the low energy conformations of 2 and 5 are similar but the energetic barriers between the relevant conformers are distinctly higher for the hybrid structure. The synthesis of 5 hinged on a regioselective functionalization of 2,4-dibromothiazole 6, a highly selective CBS-reduction of ketone 8, a Suzuki cross coupling of vinyl boronate 17 with the elaborate alkenyl iodide 16, and a productive closure of the macrocycle by RCM, which requires the selective activation of two out of eight double bonds present in the cyclization precursor 20 by the second-generation Grubbs catalyst 21.

Synthetic Route of 348-40-3. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 348-40-3, Name is 6-Fluorobenzo[d]thiazol-2-amine

Design, synthesis and evaluation of N-(substituted benzothiazol-2-yl)amides as anticonvulsant and neuroprotective

A series of N-(substituted benzothiazol-2-yl)amide derivatives 2a-h and 4a-h were synthesized by the EDC coupling reactions of substituted-benzothiazol- 2-amine with 4-oxo-4-phenylbutanoic acid/2-benzoyl benzoic acid and evaluated for their anticonvulsant and neuroprotective effect. N-(6-methoxybenzothiazol-2- yl)-4-oxo-4-phenylbutanamide (2f) emerged as the most effective anticonvulsant with median doses of 40.96 mg/kg (MES ED50), 85.16 mg/kg (scPTZ ED50) and 347.6 mg/kg (TD50). Furthermore, compound 2f displayed promising neuroprotective effect by lowering the levels of MDA and LDH; therefore, it represents a potential lead in search for safer and effective anticonvulsants having neuroprotective effects.

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 2103-99-3, Name is 4-(4-Chlorophenyl)thiazol-2-amine, molecular formula is C9H7ClN2S. In a Article，once mentioned of 2103-99-3, Formula: C9H7ClN2S

Microwave-assisted synthesis of novel N-(4-phenylthiazol-2-yl)-benzo[d]thiazole-, thiazolo[4,5-b]pyridine-, thiazolo[5,4-b]pyridine- and benzo[d]oxazole-2-carboximidamides inspired by marine topsentines and nortopsentines

We report the synthesis of novel N-(4-phenylthiazol-2-yl)-substituted benzo[d]thiazole-, thiazolo[4,5-b]pyridine-, thiazolo[5,4-b]pyridine- and benzo[d]oxazole-2-carboximidamides, which were inspired by marine topsentines and nortopsentines. Condensation of 4,5-dichloro-1,2,3-dithiazolium chloride (Appel salt) with various ortho-halogenated anilines, aminopyridines and aminophenols gave the corresponding aryliminodithiazoles in good to excellent yields. Copper(I)-mediated or nucleophilic-assisted cyclization of aryliminodithiazoles furnished cyano-functionalized benzo[d]thiazoles, thiazolo[4,5-b]- and thiazolo[5,4-b]-pyridines and benzo[d]oxazoles. The latter were condensed with substituted 4-phenylthiazol-2-amines to furnish twenty seven new polyaromatic carboximidamides in moderate to good yields.

Enantioselective Synthesis of Axially Chiral Biaryls via Copper-Catalyzed Thiolation of Cyclic Diaryliodonium Salts

Here, we report a chiral copper(II)-bisoxazoline-catalyzed enantioselective ring opening of cyclic diaryliodonium salts with heteroaryl thiols. The readily available 2-mercaptobenzoxazole and 2-mercaptobenzothiazole derivatives reacted efficiently with cyclic diaryliodonium salts and afforded various axially chiral biaryls bearing iodine and sulfur functional groups in excellent yields and enantioselectivities. The products were further transformed into diverse enantiopure alkyl biaryl sulfides, which can be employed as chiral ligands.

Selective NR1/2B N-methyl-D-aspartate receptor antagonists among indole-2-carboxamides and benzimidazole-2-carboxamides

(4-Benzylpiperidine-1-yl)-(6-hydroxy-1H-indole-2-yl)-methanone (6a) derived from (E)-1 -(4-benzylpiperidin-1-yl)-3-(4-hydroxy-phenyl)-propenone (5) was identified as a potent NR2B subunit-selective antagonist of the NMDA receptor. To establish the structure-activity relationship (SAR) and to attempt the improvement of the ADME properties of the lead, a series of compounds were prepared and tested. Several derivatives showed low nanomolar activity both in the binding and in the functional assay. In a formalin-induced hyperalgesia model in mice, 6a and (4-benzylpiperidine-1-yl)-[5(6)-hydroxy-1H-benzimidazol-2- yl]-methanone (60a) were as active as besonprodil (2) after oral administration. A CoMS1A model was developed based on binding data of a series of indole- and benzimidazole-2-carboxamides.

Firstly, quantum chemical parameters such as the highest occupied molecular orbital energy (EHOMO), lowest unoccupied molecular orbital energy (ELUMO), the energy gap between ELUMO and EHOMO (DeltaE), chemical hardness, softness, electronegativity, proton affinity, global electrophilicity, global nucleophilicity and total energy (sum of electronic and zero-point energies) were calculated and discussed with the help of HF/SDD, HF/6-311G, HF/6-31 ++G, B3LYP/SDD, B3LYP/6-311G and B3LYP/6-31 ++G methods. Then, we calculated binding energies on Fe(110) surface of aforementioned thiazole and thiadiazole derivatives to investigate the strength of the interactions between metal surface and these molecules. The theoretical data obtained are in good agreement with the experimental inhibition efficiency results earlier reported.
