6-CYCLOPROPYL- AND 6-(1-METHYLCYCLOPROPYL)-1,4-BENZODIOXANES: SYNTHESIS AND NITRATION. REARRANGEMENT OF NITRO SUBSTITUTED 6-CYCLOPROPYL-1,4-BENZODIOXANES USING CONCENTRATED SULFURIC ACID

6-Cyclopropyl- and 6-(1-methylcyclopropyl)-1,4-benzodioxanes have been synthesized as the first cyclopropyl-1,4-benzodioxanes.It was shown that nitration of these compounds occurs with retention of the three carbon ring.In contrast to simple ethers of cyclopropylphenols, nitration leads only to 7-nitro-6-cyclopropyl- and 7-nitro-6-(1-methylcyclopropyl)-1,4-benzodioxanes, respectively.Nitration of 7-nitro-6-cyclopropyl-1,4-benzodioxane occurs regioselectively to give exclusively the 7,8-dinitro product.The structure of the nitration products was confirmed by their rearrangement to the corresponding nitrosopropionyl-1,4-benzodioxanes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C10H10O3, you can also check out more blogs about2879-20-1

Structural optimization and biological evaluation of 1,5-disubstituted pyrazole-3-carboxamines as potent inhibitors of human 5-lipoxygenase

Human 5-lipoxygenase (5-LOX) is a well-validated drug target and its inhibitors are potential drugs for treating leukotriene-related disorders. Our previous work on structural optimization of the hit compound 2 from our in-house collection identified two lead compounds, 3a and 3b, exhibiting a potent inhibitory profile against 5-LOX with IC50 values less than 1 mumol/L in cell-based assays. Here, we further optimized these compounds to prepare a class of novel pyrazole derivatives by opening the fused-ring system. Several new compounds exhibited more potent inhibitory activity than the lead compounds against 5-LOX. In particular, compound 4e not only suppressed lipopolysaccharide-induced inflammation in brain inflammatory cells and protected neurons from oxidative toxicity, but also significantly decreased infarct damage in a mouse model of cerebral ischemia. Molecular docking analysis further confirmed the consistency of our theoretical results and experimental data. In conclusion, the excellent in vitro and in vivo inhibitory activities of these compounds against 5-LOX suggested that these novel chemical structures have a promising therapeutic potential to treat leukotriene-related disorders.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 2879-20-1, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2879-20-1, in my other articles.

Antiproliferative, antiandrogenic and cytotoxic effects of novel caffeic acid derivatives in LNCaP human androgen-dependent prostate cancer cells

Caffeic acid and its naturally occurring derivative caffeic acid phenethyl ester (CAPE) have antiproliferative and cytotoxic properties in a variety of cancer cell lines without displaying significant toxicity toward healthy cells, and are considered to be potential anticancer agents. However, little is known about their effects on prostate cancer cells. We synthesized and evaluated the effects of caffeic acid, CAPE (2) and 18 synthetic derivatives on cell viability and androgen-dependent cell proliferation, subcellular localisation and expression of androgen receptor (AR) and secretion of prostate-specific antigen (PSA) in LNCaP human hormone-dependent prostate cancer cells. Several synthetic derivatives of CAPE were strong, concentration-dependent cytotoxic agents in LNCaP cells with IC50 values in the 6.8-26.6 muM range, potencies that were up to five-fold greater than that of CAPE (33.7 ¡À 4.0 muM). A number of caffeic acid derivatives were inhibitors of androgen-stimulated LNCaP cell proliferation with concomitant inhibition of DHT-stimulated PSA secretion. Compound 24 was the most cytotoxic and antiproliferative caffeic acid derivative (IC50 values of 6.8 ¡À 0.3 and 2.4 ¡À 0.8 muM, respectively) inhibiting DHT-stimulated cell proliferation and PSA secretion statistically significantly at concentrations as low as 0.3 muM. Exposure to DHT increased cytoplasmic and nuclear AR levels and co-treatment with increasing concentrations of compound 24 or CAPE (2), notably, further increased these levels. In conclusion, a number of synthetic derivatives of caffeic acid are potent inhibitors of androgen-dependent prostate cancer cell proliferation and viability, acting, at least in part, via an antiandrogenic mechanism that involves increased nuclear accumulation of (presumably inactive) AR.

Conformations and laser-induced fluorescence spectroscopy of jet-cooled 2-(p-fluorophenyl)ethanol

Vibronically-resolved S1-S0 electronic spectra of 2-(p-fluorophenyl)ethanol have been studied by use of laser-induced fluorescence excitation and dispersed fluorescence spectroscopic methods in a supersonic free jet expansion. Two conformational isomers of the molecule are identified, and with the aid of the predictions of quantum chemistry calculations these are assigned to gauche and anti conformers. The assignments are corroborated by analyzing the vibronic features in the dispersed fluorescence spectra of the two conformers and their TDDFT predicted electronic transition energies. Energetic and spectral features of the conformers are compared with those of the parent molecule 2-phenylethanol.

Synthesis of n-substituted (2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamide derivatives as potent antibacterial agents and moderate enzyme inhibitors

The present research work involved the reaction of 2,3-dihydro-1,4-benzodioxin-6-amine (1) and benzenesulfonyl chloride (2) under dynamic pH control at 10 using aqueous Na2CO3. This reaction yielded 2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamide (3), which was further substituted at N-position with various alkyl/aryl halides (4a ? 4m) in N,N-dimethylformamide and catalytic amount of lithium hydride to obtain N-substituted (2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamides (5a ? 5m). The projected structures of the synthesized derivatives were confirmed using various spectral techniques (IR,1H NMR and EIMS). The synthesized derivatives were screened for antibacterial potential and inhibitory activity against lipoxygenase enzyme.

A Developability-Focused Optimization Approach Allows Identification of in Vivo Fast-Acting Antimalarials: N -[3-[(Benzimidazol-2-yl)amino]propyl]amides

Malaria continues to be a major global health problem, being particularly devastating in the African population under the age of five. Artemisinin-based combination therapies (ACTs) are the first-line treatment recommended by the WHO to treat Plasmodium falciparum malaria, but clinical resistance against them has already been reported. As a consequence, novel chemotypes are urgently needed. Herein we report a novel, in vivo active, fast-acting antimalarial chemotype based on a benzimidazole core. This discovery is the result of a medicinal chemistry plan focused on improving the developability profile of an antichlamydial chemical class previously reported by our group. (Graph Presented).

SYNTHESIS OF 2-CARBOXY-5,6-ETHYLENEDIOXYINDOLE AND ITS 3-, 4-, AND 7-HALO DERIVATIVES

A method for the synthesis of 2-carboxy-5,6-ethylenedioxyindole and its 4- and 7-chloro derivatives from 3,4-ethylenedioxyaniline and, correspondingly, its 2- and 5-chloro derivatives via Fischer reaction was developed.It was established that in the case of bromination or chlorination under mild conditions 2-carbethoxy-5,6-ethylenedioxyindole forms 3-halo derivatives, while 5,6-ethylenedioxyindole itself forms only 3,7-dihalo derivatives.The closeness in the reactivities of the 3 and 7 ring positions of 5,6-ethylenedioxyindole (as compared with indole) is in agreement with the results of calculations of the quantum-chemical reactivity indexes for electrophilic substitution.
