Identification of 2-fluoro-8-methyl-11-(1-methyl-1,2,3,6-tetrahydropyridin-4-yl)-5H-dibenzo[b,e][1,4]diazepine with clozapine-like mixed activities at muscarinic acetylcholine, dopamine, and serotonin receptors. We hypothesized that brain penetration of NDMC differed from individual to individual, and highly permeable individuals may be responders, leading to M1 agonism. In order to demonstrate the Clozapine M1-hypothesis, we considered the following profile to be required: (i) robust M1 agonism, (ii) clozapine-like binding affinity toward various GPCRs, (iii) diminish or reduce reactive metabolite for-mation, (iv) no or weak M3 agonism, and (v) high brain permeability.

Davidson, R. Stephen published the artcileThe efficiency of reaction between reactive fluorescent whitening agents and wool, Application In Synthesis of 18791-02-1, the publication is Journal of the Society of Dyers and Colourists (1988), 104(2), 86-93, database is CAplus.

Three potential fluorescent whitening agents (I; R = A, COCH₂Cl, or COCBr:CH₂) containing halogen atoms which intramol. quench fluorescence were prepared and applied to wool serge by 4 different methods to evaluate the effect of method of application on the extent to which bonds are established. The particular pad-batch method of application exerted considerable influence on the extent of covalent reaction between the wool and reactive fluorescent whitener. Complete displacement of all halogen atoms by nucleophilic groups in wool did not occur when the fluorescent whiteners were applied by cold pad-batch methods. Treatment with morpholine, Na₂CO₃, or water was necessary to develop the full potential fluorescence yield of whitener on the fabric. No fluorescence was observed when com. fluorescent whiteners, e.g., Photine HV and Blankophor BA, were applied to brominated wool, confirming that the presence of halogen atoms leads to fluorescence quenching via the heavy atom effect. The fluorescence of the whiteners was restored when the brominated fabrics were subjected to a reduction treatment. Application of the whiteners by exhaustion, with thiourea present in the liquor, at high temperatures always produced strongly fluorescent fabrics, implying that the halogen atoms were completely displaced using this application method. It is not yet possible to state whether reactions leading to covalent bonds with the fiber or hydrolysis are occurring.

Zeid, I. F. published the artcileReactions with coumarin. VIII, Formula: C9H5ClO4S, the publication is Afinidad (2003), 60(505), 295-299, database is CAplus.

A series of thiadiazole and selenadiazole derivatives was synthesized via oxidative cyclization of some semicarbazone derivatives of the types I. The later compounds were formed via reaction of coumarin-6-sulfonyl chloride 1 with m-, p-aminoacetophenone and/or o- and p-hydroxyacetophenone to give coumarin-6-sulfonamides II or the esters. Condensation of II and the esters with semicarbazide hydrochloride afforded the semicarbazones of type I. Oxidative cyclization of I with thionyl chloride led to the formation of the thiadiazole derivatives III. On the other hand, oxidative cyclization of I with selenium dioxide led to the formation of the corresponding selenadiazole derivatives

In this contribution, three novel triphenylethene-functionalized dithienylethenes I (R = H, OMe, CF₃) have been designed and prepared by appending triphenylethene moieties at one end of dithienylethene unit. They display good photochromic behaviors with excellent fatigue resistance upon irradiation with UV or visible light in THF (THF) solution Before irradiation with UV light, they exhibit aggregation induced emission (AIE) properties and luminescence behaviors in the solid state. Moreover, upon alternating irradiation with UV/visible light, they display effective fluorescent switching behaviors in the aggregated state and the solid state. The exptl. results have been validated by the d. functional theory (DFT) calculations Thus, they can be utilized as novel fluorescence switches integrated in smart, solid-state optoelectronic materials and photopharmacol.

Li, Ziyong published the artcileVisible light-activated optical switching behaviors of tetra-/triphenylethene-dithienylethene-BF₂bdk triad, Synthetic Route of 219537-97-0, the publication is Dyes and Pigments (2020), 108686, database is CAplus.

Developing new visible light-triggered fluorescent mol. photoswitches is highly desirable for potential application in the fields of photoresponsive optoelectronics and photopharmacol. In this contribution, two novel tetra-/triphenylethene-dithienylethene-BF₂bdk triads (TDB1 and TDB2) were designed and prepared by appending tetra-/triphenylethene and BF₂bdk moieties at the termini of dithienylethene unit. Before irradiation with blue light at 460-470 nm, they showed an intense emission in solution and in the PMMA film state, suggesting that the AIE effect of tetra-/triphenylethene was inhibited, and functioned only as electron-donating groups. Moreover, upon alternating irradiation with blue/NIR light, TDB1 and TDB2 displayed effective fluorescent switching behaviors and NIR photochromism in toluene and the PMMA film. Therefore, they would be utilized as novel visible light-triggered switches integrated in smart optoelectronic materials. The DFT calculations further validate the differences for their optical properties in the experiments

Liu, Qiufeng published the artcileStructure-Guided Discovery of Novel, Potent, and Orally Bioavailable Inhibitors of Lipoprotein-Associated Phospholipase A2, Application of 3-Chloro-4-fluoronitrobenzene, the publication is Journal of Medicinal Chemistry (2017), 60(24), 10231-10244, database is CAplus and MEDLINE.

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a promising therapeutic target for atherosclerosis, Alzheimer’s disease, and diabetic macular edema. Here the authors report the identification of novel sulfonamide scaffold Lp-PLA2 inhibitors derived from a relatively weak fragment. Similarity searching on this fragment followed by mol. docking leads to the discovery of a micromolar inhibitor with a 300-fold potency improvement. Subsequently, by the application of a structure-guided design strategy, a successful hit-to-lead optimization was achieved and a number of Lp-PLA2 inhibitors with single-digit nanomolar potency were obtained. After preliminary evaluation of the properties of drug-likeness in vitro and in vivo, compound 37 (4-amino-N-(4-(4-chloro-3-(trifluoromethyl)phenoxy)-3-cyanophenyl)benzenesulfonamide) stands out from this congeneric series of inhibitors for good inhibitory activity and favorable oral bioavailability in male Sprague-Dawley rats, providing a quality candidate for further development. The present study thus clearly demonstrates the power and advantage of integrally employing fragment screening, crystal structures determination, virtual screening, and medicinal chem. in an efficient lead discovery project, providing a good example for structure-based drug design.
