The flavivirus genus of the Flaviviridae family comprises Dengue, Zika and West-Nile viruses which constitute unmet medical needs as neither appropriate antivirals nor safe vaccines are available. The dengue NS2BNS3 protease is one of the most promising validated targets for developing a dengue treatment however reported protease inhibitors suffer from toxicity and cellular inefficacy. Here we report SAR on our previously reported Zika-active carbazole scaffold, culminating in prodrug compound SP-471P (EC₅₀ 1.10μM, CC₅₀ > 100μM) that generates SP-471 (I â†?II); one of the most potent, non-cytotoxic and cell-active protease inhibitors described in the dengue literature. In cell-based assays, SP-471P leads to inhibition of viral RNA replication and complete abolishment of infective viral particle production even when administered 6 h post-infection. Mechanistically, SP-471 appears to inhibit both normal intermol. protease processes and intramol. cleavage events at the NS2BNS3 junction, as well as at NS3 internal sites, all critical for virus replication. These render SP-471 a unique to date multimodal inhibitor of the dengue protease. In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6Synthetic Route of C7H4ClF3O2S).

And the article was included in Monatshefte fuer Chemie in 2021.Product Details of 777-44-6 This article mentions the following:

A series of myricetin derivatives containing sulfonate groups I (R = Ph, 2-chlorophenyl, 2-thienyl, etc.) was designed and synthesized. Preliminary antibacterial activity showed that most of the target compounds I exhibited significant biol. activities against Xanthomonas axonopodis pv. In particular, the EC₅₀ value of compound I (R = 4-nitrophenyl) was 13.76μg/cm³ against Xac, which was better than com. reagents bismerthiazol (50.32μg/cm³) and thiodiazole copper. (83.27μG/cm³), and the EC₅₀ value of compound I (3-chlorophenyl) was 11.92μg/cm³ against Xoo in vitro and the result was better than that of bismerthiazol (72.08μg/cm³) and thiodiazole copper (99.26μg/cm³). Compound I (R = 3-chlorophenyl) displayed the better in vivo activity against rice bacterial leaf blight than bismerthiazol and thiodiazole copper. Meanwhile, the antibacterial mechanism of compounds I (R = 4-nitrophenyl) and I (R = 3-chlorophenyl) was studied by scanning electron microscope (SEM). These results suggested that myricetin derivatives containing sulfonate I can be considered as new antibacterial reagents.

Occurrence, transport and environmental risk assessment of pharmaceuticals and personal care products (PPCPs) at the mouth of Jiaozhou Bay, China based on stir bar sorptive extraction was written by Shen, Qiu-Cen;Wang, Dan-Dan;Qu, Yu-Ying;Zhang, Jing;Zhang, Xue-Qing. And the article was included in Marine Pollution Bulletin in 2022.Formula: C13H9Cl3N2O This article mentions the following:

In recent years, research on pharmaceuticals and personal care products (PPCPs) in the marine environment has attracted increasing attention worldwide. However, more work is needed to improve PPCPs detection methods, specifically for seawater environments. An anal. method based on stir bar sorptive extraction (SBSE) had been developed and fully optimized for the pretreatment and detection of ten widely used PPCPs that are commonly found in seawater samples. By optimizing several variables including the material of the stir bars, extraction temperature, extraction time, ionic strength, desorption solvent, and desorption time, the optimized method has achieved excellent results in the detection and quantification of target PPCPs with detection limits ranging from 0.03 to 1 ng/L. The distribution of target PPCPs at the mouth of Jiaozhou Bay was successfully determined by this method, and the concentrations and detection frequencies of PPCPs varied greatly from N.D. to 449.36 ng/L and from 9.1% to 100%, resp. Moreover, the distributions of PPCPs were explained by the Lagrangian particle-tracking model, and the results showed that the Tuandao sewage treatment plant had the most significant impact on the study area. The environmental risk assessment results showed that several target PPCPs might pose risks to aquatic organisms. In particular, triclocarban should receive more attention and the risk quotients of the mixtures (MRQ) should not be ignored. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Formula: C13H9Cl3N2O).

Synthesis of novel amide and urea derivatives of thiazol-2-ethylamines and their activity against Trypanosoma brucei rhodesiense was written by Patrick, Donald A.;Wenzler, Tanja;Yang, Sihyung;Weiser, Patrick T.;Wang, Michael Zhuo;Brun, Reto;Tidwell, Richard R.. And the article was included in Bioorganic & Medicinal Chemistry in 2016.COA of Formula: C8H4ClNO This article mentions the following:

2-(2-Benzamido)ethyl-4-phenylthiazole I was one of 1035 mols. (grouped into 115 distinct scaffolds) found to be inhibitory to Trypanosoma brucei, the pathogen causing human African trypanosomiasis, at concentrations below 3.6 μM and nontoxic to mammalian (Huh7) cells in a phenotypic high-throughput screen of a 700,000 compound library performed by the Genomics Institute of the Novartis Research Foundation (GNF). Compound I and 72 analogs were synthesized in this laboratory by one of two general pathways. These plus 10 com. available analogs were tested against T. brucei rhodesiense STIB900 and L6 rat myoblast cells (for cytotoxicity) in vitro. Forty-four derivatives were more potent than I, including eight with IC₅₀ values below 100 nM. The most potent and most selective for the parasite was the urea analog 2-(2-piperidin-1-ylamido)ethyl-4-(3-fluorophenyl)thiazole II (IC₅₀ = 9 nM, SI > 18,000). None of 33 compounds tested were able to cure mice infected with the parasite; however, seven compounds caused temporary reductions of parasitemia (â‰?7%) but with subsequent relapses. The lack of in vivo efficacy was at least partially due to their poor metabolic stability, as demonstrated by the short half-lives of 15 analogs against mouse and human liver microsomes. In the experiment, the researchers used many compounds, for example, 3-Cyanobenzoyl chloride (cas: 1711-11-1COA of Formula: C8H4ClNO).

3-Cyanobenzoyl chloride (cas: 1711-11-1) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning.

The acute effect of the potent cyclin-dependent kinase (cdk) inhibitor (R)-roscovitine on Ca²⁺ channels inspired the development of structural analogs as a potential treatment for motor nerve terminal dysfunction. On the basis of a versatile chlorinated purine scaffold, we have synthesized ca. 20 derivatives, I [R¹ = n-Pr, Me, CHMe₂, R² = CH₂Ph, CH(Ph)₂, 3-pyridinylmethyl, etc.], and characterized their N-type Ca²⁺ channel agonist action. I were prepared by reacting 2,6-dichloro-9H-purine with R¹X/K₂CO₃/DMSO (X = halo), followed by reaction with R²NH₂/NEt₂/BuOH, which gave the 4-chloro-6-amino derivatives; the final step consisted of treating the latter compounds with (R)-2-amino-1-butanol at 170°C. Agents that showed strong agonist effects were also characterized in a kinase panel for their off-target effects. Among several novel compounds with diminished cdk activity, we identified a new lead structure with a 4-fold improved N-type Ca²⁺ channel agonist effect and a 22-fold decreased cdk2 activity as compared to (R)-roscovitine.
