The complex pathophysiol. of depression, together with the limits of currently available antidepressants, has resulted in the continuous quest for alternative therapeutic strategies. Numerous findings suggest that pharmacol. blockade ofα2-adrenoceptor might be beneficial for the treatment of depressive symptoms by increasing both norepinephrine and serotonin levels in certain brain areas. The antidepressant properties of 5-HT7 receptor antagonists have been widely demonstrated in a large set of animal models. Considering the potential therapeutic advantages in targeting both α2-adrenoceptors and 5-HT7 receptors, a small series of arylsulfonamide derivatives of (dihydrobenzofuranoxy)ethyl piperidines I (Ar = 4-fluorophenyl, naphthalen-1-yl, isoquinolin-4-yl, etc.; m = 0,1) as dually active ligands were designed. Following green chem. principles, the designed compounds were synthesized entirely using a sustainable mechanochem. approach. The identified compound I (Ar = 5-chloro-2-fluorophenyl (II)) behaved as a potent α2A/5-HT7 receptor antagonist and displayed moderate-to-high selectivity over α1-adrenoceptor subtypes and selected serotonin and dopaminergic receptors. Finally, (II) improved performance of mice in the forced swim test, displaying similar potency to the reference drug mirtazapine.

The design and synthesis of a class of 2,3-dihydrobenzofuran-2-carboxylic acids, e.g., I, as highly potent and subtype-selective PPARα agonists are reported. Systematic study of structure-activity relationships has identified several key structural elements within this class for maintaining the potency and subtype selectivity. Select compounds were evaluated in animal models of dyslipidemia using Syrian hamsters and male Beagle dogs, and all these compounds displayed excellent cholesterol- and triglyceride-lowering activity at dose levels that were much lower than the marketed weak PPARα agonist fenofibrate.

Ghosh, Santanu; Jana, Chandan K. published the artcile< Metal-Free Thermal Activation of Molecular Oxygen Enabled Direct α-CH2-Oxygenation of Free Amines>, HPLC of Formula: 53581-86-5, the main research area is thermal activation mol oxygen; alpha methylene oxygenation amine; amide lactam preparation.

Direct oxidation of α-CH2 group of free amines is hard to achieve due to the higher reactivity of amine moiety. Therefore, oxidation of amines involves the use of sophisticated metallic reagents/catalyst in the presence or absence of hazardous oxidants under sensitive reaction conditions. A novel method for direct C-H oxygenation of aliphatic amines through a metal-free activation of mol. oxygen has been developed. Both activated and unactivated free amines were oxygenated efficiently to provide a wide variety of amides (primary, secondary) and lactams under operationally simple conditions without the aid of metallic reagents and toxic oxidants. The method has been applied to the synthesis of highly functionalized amide-containing medicinal drugs, such as O-Me-alibendol and -buclosamide.

A series of different mol. architecture (homo, random, block and gradient type) copolymers PI-3(a-e) were synthesized by solution polycondensation. Three different bischloroimide monomers [bischlorophthalimide 2a, bischloronaphthalimide 2b and bischloro (naphthalimide-phthalimide) 2c] were prepared and reacted with 4,4′-thiobisbenzenethiol by different synthetic routes. The chem. reactivity of these monomers 2(a-c) was examined by kinetic study of model compounds N-phenyl-4-chloro-1,8-naphthalimide and N-phenyl-4-chlorophthalimide using gas chromatog. mass spectrometry (GC-MS). The difference in chem. reactivity of monomers was utilized to design mol. architecture of copolymer, and the influence of comonomers sequence on copolymer properties is investigated. The synthesized copolyimides PI-3(a-e) integrated the excellent properties of naphthalimide and phthalimide as good organosoly., high glass transition temperature of 198-319°C and good thermooxidative stability based on 5% weight loss temperature of 492-524°C and 480-532°C in nitrogen and air, resp. Gradient type sequence PI-3 e offers a good combination of phthalimide and naphthalimide groups in copolymers for improved thermal and mech. properties.

In order to find efficient new antitumor drugs, a series of novel trifluoromethyl-substituted pyrimidine derivatives were designed and synthesized and the bioactivity against four human tumor cells (PC-3, MGC-803, MCF-7 and H1975) was evaluated by MTT assay. Compound I displayed potent anti-proliferative activity on H1975 (IC50 = 2.27 μM), which was better than the pos. control 5-FU (IC50 = 9.37 μM). Further biol. evaluation studies showed that compound I apoptosis of H1975 cells and arrested the cell cycle at G2/M phase. Furthermore, compound I induced H1975 cells apoptosis through increasing the expression of pro-apoptotic proteins Bax and p53 and down-regulating the anti-apoptotic protein Bcl-2. In addition, compound I was able to be tightly embedded in the active pocket of EGFR. These results demonstrated that compound I has a potential as a lead compound for further investigation.

A series of novel 1,3,4-thiadiazole amide derivatives I [R = cyclohexyl, Ph, Bn, etc.] containing a protocatechuic acid moiety were synthesized and structurally characterized. In addition, the corresponding imino and amino analogs of a 1,3,4-thiadiazole amide derivative I [R = Ph] were prepared to compare the effects of the structural changes on the radical-scavenging activity. The obtained compounds I were examined for their antioxidative potential by DPPH and ABTS assays. In addition, selected compounds were studied by d. functional theory (DFT) and cyclic voltammetry experiments The tested compounds showed high potential to scavenging DPPH radical and ABTS radical cation compared with the referent antioxidants ascorbic acid and nordihydroguaiaretic acid (NDGA). On the basis of the calculated thermodn. parameters, it can be concluded that the sequential proton loss electron transfer (SPLET) mechanism represented the most probable reaction path in a polar solvent for DPPH radical-scavenging activity. On the other hand, the single electron transfer followed by proton transfer (SET-PT) could be a likely mechanistic pathway in the case of an ABTS radical cation.

Polard, T.; Jean, S.; Merlina, G.; Laplanche, C.; Pinelli, E.; Gauthier, L. published the artcile< Giemsa versus acridine orange staining in the fish micronucleus assay and validation for use in water quality monitoring>, Name: 2-(Bis(2-chloroethyl)amino)-1,3,2-oxazaphosphinane 2-oxide hydrate, the main research area is staining micronucleus assay acridine orange Giemsa water monitoring Carassius.

This study concerns a comparative anal. of the acridine orange and Giemsa staining procedures for the fish erythrocyte micronucleus assay. The goal was to optimize the assay in the context of field water monitoring. Fish (Carassius carassius) were exposed to a reference genotoxic agent, cyclophosphamide monohydrate 5 mg L-1 for 2, 4, and 6 days before testing. Slides from each individual were scored using the two procedures. The results show that the assay was more sensitive when acridine orange was used. When slides were Giemsa stained, the presence of ambiguous artifacts, leading to false positives and increasing random variance, reduced the contrast between exposed and control samples. Acridine Orange staining was then applied in the context of water quality monitoring. Fish were exposed for 4 days to water sampled in two hydrol. contexts: basal flow and spring flood. The results show that exposure to spring flood water in an agricultural stream can induce mutagenicity.
