Structure-Activity Relationships of the MEPicides: N-Acyl and O-Linked Analogs of FR900098 as Inhibitors of Dxr from Mycobacterium tuberculosis and Yersinia pestis was written by San Jose, Geraldine;Jackson, Emily R.;Haymond, Amanda;Johny, Chinchu;Edwards, Rachel L.;Wang, Xu;Brothers, R. Carl;Edelstein, Emma K.;Odom, Audrey R.;Boshoff, Helena I.;Couch, Robin D.;Dowd, Cynthia S.. And the article was included in ACS Infectious Diseases in 2016.Reference of 5335-05-7 This article mentions the following:

Despite continued research efforts, the threat of drug resistance from a variety of bacteria continues to plague clin. communities. Discovery and validation of novel biochem. targets will facilitate development of new drugs to combat these organisms. The methylerythritol phosphate (MEP) pathway to make isoprene units is a biosynthetic pathway essential to many bacteria. We and others have explored inhibitors of the MEP pathway as novel antibacterial agents. Mycobacterium tuberculosis, the causative agent of tuberculosis, and Yersinia pestis, resulting in the plague or “black death,” both rely on the MEP pathway for isoprene production 1-Deoxy-D-xylulose 5-phosphate reductoisomerase (Dxr) catalyzes the first committed step in the MEP pathway. We examined two series of Dxr inhibitors based on the parent structure of the retrohydroxamate natural product FR900098. The compounds contain either an extended N-acyl or O-linked alkyl/aryl group, and are designed to act as bisubstrate inhibitors of the enzyme. While nearly all of the compounds inhibited both Mtb and Yp Dxr to some extent, compounds generally displayed more potent inhibition against the Yp homolog, with the best analogs displaying nM IC₅₀ values. In bacterial growth inhibition assays, the phosphonic acids generally resulted in poor antibacterial activity, likely a reflection of inadequate permeability. Accordingly, di-Et and diPOM prodrug esters of these compounds were made. While the added lipophilicity did not enhance Yersinia activity, the compounds showed significantly improved antitubercular activities. The most potent compounds have Mtb MIC values of 3-12 μg/mL. Taken together, we have uncovered two series of analogs that potently inhibit Dxr homologs from Mtb and Yp. These inhibitors of the MEP pathway, termed MEPicides, serve as leads for future analog development. In the experiment, the researchers used many compounds, for example, Chloromethyl benzoate (cas: 5335-05-7Reference of 5335-05-7).

Chloromethyl benzoate (cas: 5335-05-7) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Reference of 5335-05-7

K₂CO₃-Catalyzed Rapid Conversion of N-Sulfonylhydrazones to Sulfinates was written by Korawat, Harshita Singh;Basak, Ashok K.. And the article was included in ACS Omega in 2020.HPLC of Formula: 777-44-6 This article mentions the following:

N-Sulfonylhydrazones derived from alkyl, aryl, and heteroaryl aldehydes and ketones undergo rapid conversion into the corresponding sulfinates when heated with 10 mol % K₂CO₃ in N,N’-dimethylethylene urea (DMEU) at elevated temperature The reaction conditions are amenable to several functional groups and suitable for gram-scale synthesis. Under these base-catalyzed conditions, N-tosylhydrazones derived from O-allylated and O-propargylated 2-hydroxyarylaldehydes do not undergo the well-established intramol. [3 + 2]-cycloaddition reactions and generate corresponding sulfinates in good yields. The base-catalyzed transformation proceeds via crucial rapid intermol. protonation of the diazo intermediate to generate diazonium ion, which upon nucleophilic displacement by the sulfonyl ion provides the desired sulfinate selectively. In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6HPLC of Formula: 777-44-6).

3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).HPLC of Formula: 777-44-6

And the article was included in Scientific Reports in 2022.Recommanded Product: 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride This article mentions the following:

In response to an increasing desire for modern industries to be both green and sustainable, there has been increasing research focus on the reutilization of natural waste materials to effectively remove and degrade toxic wastewater effluents. One interesting food industry waste product is clam shell. Here a new photocatalytic nanomaterial derived from marine clam shells was successfully prepared and characterized. Thereafter the material was applied for the removal of two target dyes from aqueous solution, where the effect of both catalyst dose and initial dye concentration on adsorption and photocatalysis was investigated. The maximum adsorption capacities of methylene blue (100 mg/L) and Congo red (500 mg/L) were 123.45 mg/g and 679.91 mg/g, resp., where adsorption followed pseudo second order kinetics predominantly via a chem. adsorption process. The photodegradation removal efficiencies of the two dye solutions under visible light irradiation were 99.6% and 83.3% for MB and CR, resp. The excellent degradation performance in a mixed dye solution, with strong degradation capability and low cost, demonstrated that the clam shell catalyst material was a good candidate for practical field remediation of dye contaminated wastewater.

And the article was included in Journal of Medicinal Chemistry in 2009.SDS of cas: 6834-42-0 This article mentions the following:

BRAF is a serine/threonine kinase that is mutated in a range of cancers, including 50-70% of melanomas, and has been validated as a therapeutic target. The authors have designed and synthesized mutant BRAF inhibitors containing pyridoimidazolone as a new hinge-binding scaffold. Compounds have been obtained which have low nanomolar potency for mutant BRAF (12 nM for compound I) and low micromolar cellular potency against a mutant BRAF melanoma cell line, WM266.4. The series benefits from very low metabolism, and pharmacokinetics (PK) that can be modulated by methylation of the NH groups of the imidazolone, resulting in compounds with fewer H-donors and a better PK profile. These compounds have great potential in the treatment of mutant BRAF melanomas. In the experiment, the researchers used many compounds, for example, 2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0SDS of cas: 6834-42-0).

1-(2-Hydroxybenzoyl)-thiosemicarbazides are promising antimicrobial agents targeting D-alanine-D-alanine ligase in bacterio was written by Ameryckx, Alice;Thabault, Leopold;Pochet, Lionel;Leimanis, Serge;Poupaert, Jacques H.;Wouters, Johan;Joris, Bernard;Van Bambeke, Francoise;Frederick, Raphael. And the article was included in European Journal of Medicinal Chemistry in 2018.Application of 6590-96-1 This article mentions the following:

A series of 1-(2-hydroxybenzoyl)thiosemicarbazides I [R¹ = H, 2-OH, 4-F, etc.; R² = Ph, 1-naphthyl, 3-pyridinyl, etc.] inhibitors of D-Ala-D-Ala ligase (Ddl) were designed and synthesized in order to target resistant strains of bacteria. Among these, compound I [R¹ = 2-OH, R² = 3,4-di-ClC₆H₃] was identified as a potent Ddl inhibitor with activity in the micromolar range. This compound, possessing strong antimicrobial activity including against multidrug resistant strains, was proven to act through a bactericidal mechanism and demonstrated very low cytotoxicity on THP-1 human monocytic cell line. Inhibition of Ddl activity by compound I compound I [R¹ = 2-OH, R² = 3,4-di-ClC₆H₃] was confirmed in-bacterio using UPLC-MS/MS by demonstrating an increase in D-Ala intracellular pools accompanied by a commensurate decrease in D-Ala-D-Ala. Further structure-activity relationships (SARs) studies provided evidence that the hydroxyl substituent in the 2-position (R1) of the benzoylthiosemicarbazide scaffold was essential for the enzymic inhibition. This work thus highlightened the 1-(2-hydroxybenzoyl)-thiosemicarbazide motif as a very promising tool for the development of novel antibacterial compounds acting through an interesting mechanism of action and low cytotoxicity. In the experiment, the researchers used many compounds, for example, 2,4-Dichlorophenylisothiocyanate (cas: 6590-96-1Application of 6590-96-1).

2,4-Dichlorophenylisothiocyanate (cas: 6590-96-1) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Application of 6590-96-1

Assessment of the effectiveness of onsite exsitu remediation by enhanced natural attenuation in the Niger Delta region, Nigeria was written by Okparanma, Reuben N.;Azuazu, Ikeabiama;Ayotamuno, Josiah M.. And the article was included in Journal of Environmental Management in 2017.SDS of cas: 3386-33-2 This article mentions the following:

This study was conducted to quantify and rank the effectiveness of onsite exsitu remediation by enhanced natural attenuation using soil quality index. The investigation was conducted at three oil spill sites in the Niger Delta (5.317°N, 6.467°E), Nigeria with a predominance of Oxisols. Baseline assessment and a two-step post-remediation monitoring of the sites were conducted. Target contaminants including total petroleum hydrocarbon (TPH) and BTEX (benzene, toluene, ethylbenzene, and xylene) were analyzed by gas chromatog.-mass spectrometry. Results of the baseline assessment showed that TPH concentrations across the study sites averaged between 5113 and 7640 mg/kg at 0- to 1-m depth, which was higher than the local regulatory value of 5000 mg/kg. The soil quality index across the sites ranged between 68 and 45, suggesting medium to high potential ecol. health risks with medium to high priority for remediation. BTEX concentrations followed a similar trend. However, after remediation TPH degraded rapidly initially and then slowly but asymptotically during the post-remediation monitoring period. Then, soil quality index across the study sites ranged between 100 and 58, indicating very low to medium potential ecol. health risks. This demonstrates the effectiveness of onsite exsitu remediation by enhanced natural attenuation as a remediation strategy for petroleum-contaminated soils, which holds great promise for the Niger Delta province. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2SDS of cas: 3386-33-2).

1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.SDS of cas: 3386-33-2
