New banana shaped A?D?pi?D?A type organic dyes containing two anchoring groups for high performance dye-sensitized solar cells

Two new bent A?D?pi?D?A type organic dyes (MA-1 and MA-2) consisting of carbazole and phenothiazine moieties as electron donors with 2,1,3-benzothiadiazole as a pi-linker with two end-anchoring groups are designed, synthesized and tested in DSSCs. The photophysical and electrochemical properties of the dyes are investigated in detail. Incorporation of phenothiazine unit in MA-2 resulted in high HOMO level (0.62?V vs. NHE), with a red shift in absorption maxima and broadening of the absorption spectrum. Under standard global AM 1.5 solar conditions, the MA-2 sensitized solar cells exhibited a short circuit photocurrent density of 13.1?mA?cm?2, an open-circuit voltage of 0.73?V, a fill factor of 0.72, corresponding to an overall conversion efficiency of 6.87%. Such design and development of molecular dyes are useful for improving the overall efficiency of DSSCs.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 3939-23-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3939-23-9, in my other articles.

An Inhibitor of the Interaction of Survivin with Smac in Mitochondria Promotes Apoptosis

Herein we report the first small molecule that disrupts the survivin-Smac interaction taking place in mitochondria. The inhibitor, PZ-6-QN, was identified by initially screening a phenothiazine library using a fluorescence anisotropy assay and then conducting a structure?activity relationship study. Mutagenesis and molecular docking studies suggest that PZ-6-QN binds to survivin similarly to the known Smac peptide, AVPI. The results of the effort also show that PZ-6-QN exhibits good anticancer activity against various cancer cells. Moreover, cell-based mechanistic studies provide evidence for the proposal that PZ-6-QN enters mitochondria to inhibit the survivin-Smac interaction and promotes release of Smac and cytochrome c from mitochondria into the cytosol, a process that induces apoptosis in cancer cells. Overall, the present study suggests that PZ-6-QN can serve as a novel chemical probe for study of processes associated with the mitochondrial survivin-Smac interaction and it will aid the discovery of novel anticancer agents.

Half-Chair Conformations of Unsaturated Heterocyclic Compounds

The vicinal proton coupling constants were obtained for some 6-membered ring unsaturated heterocyclic compounds.The R values and ring dihedral angles were determined and found to be consistent with half-chair conformations.Relative to saturated heterocyclic compounds, the effect of the sulfur atom on ring puckering was attenuated.However, an increase in ring puckering resulted from the sulfone group and was attributed to torsional energy.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 126456-43-7!, 3080-99-7

Photodynamic antimicrobial chemotherapy has an overt killing effect on periodontal pathogens? A systematic review of experimental studies

The periodontal disease (PD) etiology is mainly associated with some bacterial strains, such as Porphyromonas gingivalis (P. gingivalis). Nonsurgical root scaling (e.g., antibiotics) may achieve a temporary decrease in the P. gingivalis level, yet it cannot eradicate the microorganism. Moreover, antibiotics can lead to bacterial resistance and undesirable side effects. This systematic review was performed to identify animal data defining antimicrobial photodynamic therapy (PACT) role on experimental PD models in the treatment of P. gingivalis. Embase, MEDLINE, and PubMed were examined for studies published from January 1980 to August 2018. MeSH terms and Scopus data were used to find more related keywords. Four studies were selected and reviewed by two independent researches with a structured tool for rating the research quality. The beneficial effect of PACT included reductions in P. gingivalis counts, bleeding on probing, redness, and inflammation on multiple sites (i.e., first molar, dental implants; subgingival; and mandibular premolars). Although our results suggest that PACT displays antimicrobial action on P. gingivalis, thus improving the PD, a nonuniformity in the PACT protocol and the limited number of studies included lead to consider that the bactericidal efficacy of PACT against periodontal pathogens in PD remains unclear.

Electrochemical Oxidative C?H Amination of Phenols: Access to Triarylamine Derivatives

Dehydrogenative C?H/N?H cross-coupling serves as one of the most straightforward and atom-economical approaches for C?N bond formation. In this work, an electrochemical reaction protocol has been developed for the oxidative C?H amination of unprotected phenols under undivided electrolytic conditions. Neither metal catalysts nor chemical oxidants are needed to facilitate the dehydrogenation process. A series of triarylamine derivatives could be obtained with good functional-group tolerance. The electrolysis is scalable and can be performed at ambient conditions.

Development of high-affinity 5-HT3 receptor antagonists. Structure- affinity relationships of novel 1,7-annelated indole derivatives. 1

On the basis of the structures of ondansetron and GR 65,630, its ring- opened C-linked methylimidazole analogue, novel 1,7-annelated indole derivatives were synthesized as potential 5-HT3 antagonists. Receptor binding studies show that all compounds display a high affinity for the 5- HT3 receptors. In both series annelation results in compounds being 7 and 4 times more potent than the references ondansetron and GR 65,630, respectively. Similar to ondansetron, the 1,7-annelated indoles show little stereoselectivity. The (-)-isomers are only slightly more potent than the (+)-isomers. The receptor binding profile of l-10-[(2-methyl-1H-imidazol-1- yl)methyl]-5,6,8,9,10,11-hexahydro-4H-pyrido[3,2,1-jk]carbazol-11-one hydrochloride (24b) (INN cilansetron) shows that the compound displays, besides a high affinity for 5-HT3 receptors (K(i) = 0.19 nM), a weak affinity for sigma-receptors (K(i) = 340 nM), muscarine M1 receptors (K(i) = 910 nM), and 5-HT4 receptors (K(i) = 960 nM) and no affinity (K(i) ? 5000 nM) for all the other receptor types tested (n = 37). The new compounds fit the proposed necessary chemical template for binding: a heteroaromatic ring system, a coplanar carbonyl group, and a nitrogen center at well-defined distances. The enhanced potency of the annelated 1,7-indole derivatives indicates that the extra ring provides a favorable hydrophobic area for interaction with the 5-HT3 receptor site. In vivo cilansetron is more potent and induces less central side effects than ondansetron. At present cilansetron is in clinical trials.
