Postischemic brain damage in stroke is proceded with complicated pathol. events, and so multimodal drug treatments may offer better therapeutic means for improving clin. outcomes. Here, we report robust neuroprotective effects of a novel compound, 2-((2-oxopropanoyl)oxy)-4-(trifluoromethyl)benzoic acid (OPTBA), a 2-hydroxy-4-trifluoromethyl benzoic acid (HTB, a metabolite of triflusal)-pyruvate ester. I.v. administration of OPTBA (5 mg/kg) 3 or 6 h after middle cerebral artery occlusion (MCAO) in Sprague-Dawley rats reduced infarct volumes to 38.5 ± 11.4% and 46.5 ± 15.3%, resp., of that of MCAO controls, and ameliorated motor impairment and neurol. deficits. Importantly, neuroprotective effects of OPTBA were far greater than those afforded by combined treatment of HTB and pyruvate. Furthermore, OPTBA suppressed microglial activation and proinflammatory cytokine inductions more effectively than HTB/pyruvate co-treatment in the postischemic brain and LPS-treated cortical slice cultures and also attenuated NMDA-induced neuronal death in hippocampal slice cultures. LC-MS anal. demonstrated that OPTBA was hydrolyzed to HTB and pyruvate with a t_1/2 of 38.6 min in blood and 7.2 and 2.4 h in cortex and striatum, resp., and HTB was maintained for more than 24 h both in blood and brain tissue. Together these results indicate OPTBA acts directly and via its hydrolysis products, thus acting as a multimodal neuroprotectant in the postischemic brain.

Anagnostou, Athanasius published the artcileErythropoietin has a mitogenic and positive chemotactic effect on endothelial cells, Product Details of C18H20N2O12, the publication is Proceedings of the National Academy of Sciences of the United States of America (1990), 87(15), 5978-82, database is CAplus and MEDLINE.

A dose-dependent proliferative action of human recombinant erythropoietin on human umbilical vein endothelial cells and bovine adrenal capillary endothelial cells was observed Binding studies with radioiodinated recombinant human erythropoietin revealed a large number (≈27,000) of an apparent single class of receptors with an affinity in the 10^-9 M range. Linkage of the radiolabeled ligand to its receptor via a bifunctional crosslinking agent allowed identification of an endothelial cell protein of 45 kilodaltons as the principal receptor associated with this mitogenic effect of erythropoietin. Recombinant human erythropoietin also enhanced the migration of endothelial cells.

Rats, mice, guinea pigs, and cats, given orally repeated toxic doses of the antihelminthic compounds diphesyl (I) [34987-38-7] and naphthamone [3818-50-6] showed inflammation of the gastric mucosa, proliferation of the superficial squamous epithelium, and hyperkeratosis of the forestomach. These effects were reversible, and were probably due to the hydroxynaphthoate anion in the drugs.

Wongrakpanich, Amaraporn published the artcilePhyllanthus emblica extract-loaded transfersomes for hair follicle targeting: phytoconstituents, characterization, and hair growth promotion, COA of Formula: C5H12O2, the publication is Journal of Oleo Science (2022), 71(7), 1085-1096, database is CAplus and MEDLINE.

Phyllanthus emblica Linn. (PE) has been used to promote hair growth for decades. In this study, dried PE fruit powder was extracted, tested for biol. activities, and loaded into transfersomes for hair follicle targeting. Before lyophilization, PE fruit powder was extracted using 2 solvent systems, water and 30% ethanol. The PE 30% ethanolic extract had higher antioxidant activity and total phenolic content than the PE aqueous extract However, the cytotoxicity of the PE 30% ethanolic extract was higher than that of PE aqueous extract As a result, the PE aqueous extract was analyzed using ultra-performance liquid chromatog. and found that the major component of the PE aqueous extract was gallic acid. Afterward, the PE aqueous extract was tested for its potential to activate the expression of genes involved in hair growth promotion in human keratinocytes. At a non-toxic concentration (10 μg/mL), this extract promoted various growth factors comparable to 1% minoxidil. PE-loaded transfersomes were prepared to deliver the PE aqueous extract to the hair follicle. The particle size and polydispersity index of PE-loaded transfersomes were 228 nm and 0.25, resp. After 3 mo of storage, the particle size at 4°C and 30°C was 218 nm and 241 nm, resp., which was comparable to its initial size. However, at 40°C, the particle size dramatically increased (315 nm). The fluorescent agent, rhodamine B, was used to evaluate the potential of transfersomes to target hair follicles. Rhodamine B transfersomes had better penetration and accumulation in hair follicles than rhodamine B solution To conclude, the PE aqueous extract, mainly composed of gallic acid, can activate hair growth gene expression. The extract can be loaded into hair follicles targeting transfersomes. Thus, PE-loaded transfersomes are a promising delivery system for hair follicle targeting to promote hair growth.

Huang, Pan published the artcileDiscovery of a Dual Tubulin Polymerization and Cell Division Cycle 20 Homologue Inhibitor via Structural Modification on Apcin, Related Products of alcohols-buliding-blocks, the publication is Journal of Medicinal Chemistry (2020), 63(9), 4685-4700, database is CAplus and MEDLINE.

Apcin is one of the few compounds that have been previously reported as a Cdc20 specific inhibitor, although Cdc20 is a very promising drug target. We reported here the design, synthesis, and biol. evaluations of 2,2,2-trichloro-1-aryl carbamate derivatives as Cdc20 inhibitors. Among these derivatives, compound 9f(I) was much more efficient than the pos. compound apcin in inhibiting cancer cell growth, but it had approx. the same binding affinity with apcin in SPR assays. It is possible that another mechanism of action might exist. Further evidence demonstrated that compound 9f also inhibited tubulin polymerization, disorganized the microtubule network, and blocked the cell cycle at the M phase with changes in the expression of cyclins. Thus, it induced apoptosis through the activation of caspase-3 and PARP. In addition, compound 9f inhibited cell migration and invasion in a concentration-dependent manner. These results provide guidance for developing the current series as potential new anticancer therapeutics.

Elam, Christopher published the artcileDiscovery of novel SERCA inhibitors by virtual screening of a large compound library, Name: 2,5-Bis(2,4,4-trimethylpentan-2-yl)benzene-1,4-diol, the publication is European Journal of Medicinal Chemistry (2011), 46(5), 1512-1523, database is CAplus and MEDLINE.

Two screening protocols based on recursive partitioning and computational ligand docking methodologies, resp., were employed for virtual screens of a compound library with 345,000 entries for novel inhibitors of the enzyme sarco/endoplasmic reticulum calcium ATPase (SERCA), a potential target for cancer chemotherapy. A total of 72 compounds that were predicted to be potential inhibitors of SERCA were tested in bioassays and 17 displayed inhibitory potencies at concentrations below 100 μM. The majority of these inhibitors were composed of two Ph rings tethered to each other by a short link of one to three atoms. Putative interactions between SERCA and the inhibitors were identified by inspection of docking-predicted poses and some of the structural features required for effective SERCA inhibition were determined by anal. of the classification pattern employed by the recursive partitioning models.

The synthesis of N-(2-SF₅-ethyl)amines e.g., I is reported via the S_N2 reaction between various amines, e.g., Me (2S)-pyrrolidine-2-carboxylate and 2-(pentafluoro-λ⁶-sulfanyl)ethyl trifluoromethanesulfonate as the SF₅-containing electrophile. A total of 14 examples of SF₅-containing aliphatic amines were synthesized, with yields going from 19 to 92%. Moreover, the effect of the SF₅ substituent on the basicity and the lipophilicity of the amine was evaluated, and the SF₅ group showed to decrease both the pK_aH and the log D (pH = 7.0) values.
