The efficiency of 21 P compounds in epoxy coatings varied in series acids > phosphates .sim. phosphites >> phosphonates. The weight loss, char area, and char volume of epoxy coatings containing tri-Ph phosphite [101-02-0] and tri-Me phosphate [512-56-1] were generally minimized while the intumescence maximized as the concentration of amine catalyst, P compound, and film thickness were increased over a wide range. A combination of a high melting insoluble chlorocarbon and phosphoryltrianilide [5326-10-3] were used to prepare fire retardant pigmented alkyd and chlorinated alkyd paints with excellent water and scrub resistance. The fire retardant properties of epoxy coatings containing (PhO)3P were unchanged after immersion in water at 50.deg. for 24 hr.

Nasim, Muhammad Jawad published the artcilePronounced activity of aromatic selenocyanates against multidrug resistant ESKAPE bacteria, SDS of cas: 620-20-2, the publication is New Journal of Chemistry (2019), 43(15), 6021-6031, database is CAplus.

Selenocyanates represent an interesting class of organic selenium compounds Due to their similarity with better known natural (iso-)thiocyanates, they promise high biol. activity and may also be metabolized to other reactive selenium species (RSeS), such as selenols, diselenides, and seleninic acids. Thirteen arylmethyl selenocyanates were synthesized and evaluated for potential antimicrobial, nematicidal, and cytotoxic activity. The compounds exhibit pronounced antimicrobial activity against various strains of Gram-pos. and Gram-neg. bacteria and yeasts, including multidrug resistant strains. The results obtained so far demonstrate that these arylmethyl selenocyanates are also non-mutagenic and have limited cytotoxicity against human cells. Here, benzyl selenocyanate represents the most active anti-ESKAPE agent, with potent activity against multidrug resistant MRSA strains (HEMSA 5) with a competitive MIC value of just 0.76 μg/mL (3.88 μM), whereas it exhibits low(er) cytotoxicity (IC₅₀ = 31 μM) and no mutagenicity against mammalian cells. Due to this selective antimicrobial activity, aromatic selenocyanates may provide an interesting lead in the development of antimicrobial agents, particularly in the context of drug resistance.

Grabarczyk, Malgorzata published the artcileHydroxy lactones with the gem-dimethylcyclohexane system – Synthesis and antimicrobial activity, Recommanded Product: ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Arabian Journal of Chemistry (2019), 12(8), 2280-2288, database is CAplus.

Two new lactones comprising the gem-dimethylcyclohexane ring: 2-chloro-5,5-dimethyl-9-oxabicyclo[4.3.0]nonan-8-one and 2-bromo-5,5-dimethyl-9-oxabicyclo[4.3.0]nonan-8-one as well as the already known 2-iodo-5,5-dimethyl-9-oxabicyclo[4.3.0]nonan-8-one, were obtained from (6,6-dimethylcyclohex-2-en-1-yl)acetic acid. These lactones were used as substrates for the screening of biotransformation by whole cells of nine fungal strains (Fusarium species, Syncephalastrum racemosum and Cunninghamella japonica). Some of these microorganisms (mainly Fusarium species) transformed all three lactones during the hydrolytic dehalogenation into 2-hydroxy-5,5-dimethyl-9-oxabicyclo[4.3.0]nonan-8-one. It is worth noting that two microorganisms (Fusarium culmorum and Fusarium scirpi) converted iodolactone with very high enantioselectivity (75.1% and 91.6%, resp.). The (+) isomer of hydroxy lactone was preferred. At the last step the hydroxy lactone obtained during biotransformation was examined for its biol. activity against bacteria, yeasts and fungi. It was found that this compound inhibits growth of some tested microorganisms.

Bhhatarai, Barun published the artcileEvaluation of TOPKAT, Toxtree, and Derek Nexus in Silico Models for Ocular Irritation and Development of a Knowledge-Based Framework To Improve the Prediction of Severe Irritation, Formula: C6H3ClFNO2, the publication is Chemical Research in Toxicology (2016), 29(5), 810-822, database is CAplus and MEDLINE.

Assessment of ocular irritation is an essential component of any risk assessment. A number of (Q)SARs and expert systems have been developed and are described in the literature. Here, the authors focus on three in silico models (TOPKAT, BfR rulebase implemented in Toxtree, and Derek Nexus) and evaluate their performance using 1644 inhouse and 123 European Center for Toxicol. and Ecotoxicol. of Chems. (ECETOC) compounds with existing in vivo ocular irritation classification data. Overall, the in silico models performed poorly. The best consensus predictions of severe ocular irritants were 52 and 65% for the inhouse and ECETOC compounds, resp. The prediction performance was improved by designing a knowledge-based chem. profiling framework that incorporated physicochem. properties and electrophilic reactivity mechanisms. The utility of the framework was assessed by applying it to the same test sets and three addnl. publicly available in vitro irritation data sets. The prediction of severe ocular irritants was improved to 73-77% if compounds were filtered on the basis of AlogP_MR (hydrophobicity with molar refractivity). The predictivity increased to 74-80% for compounds capable of preferentially undergoing hard electrophilic reactions, such as Schiff base formation and acylation. This research highlights the need for reliable ocular irritation models to be developed that take into account mechanisms of action and individual structural classes. It also demonstrates the value of profiling compounds with respect to their chem. reactivity and physicochem. properties that, in combination with existing models, results in better predictions for severe irritants.

Chen, Yiding published the artcileCopper(I)-catalyzed sulfonylative Suzuki-Miyaura cross-coupling, Name: (4-((4-Chlorobenzyl)oxy)phenyl)boronic acid, the publication is Chemical Science (2017), 8(4), 3249-3253, database is CAplus and MEDLINE.

By using a simple copper(I) catalyst a high yielding sulfonylative-Suzuki-Miyaura cross-coupling reaction was developed. The process provided a single step route to diaryl sulfones from the direct combination of arylboronic acids, sulfur dioxide and aryl iodides, and represents the first sulfonylative variant of a classic cross-coupling reaction. Sulfur dioxide was delivered from the surrogate reagent, DABSO. Variation of the reaction conditions allowed interruption of the sulfonylative-Suzuki coupling, resulted in the formation of a presumed Cu-sulfinate intermediate. These sulfinates was trapped as their sodium salts and treated with electrophiles to allow access to arylalkyl sulfones, β-hydroxyl sulfones, sulfonamides and sulfonyl fluorides.

Apgar, James M. published the artcileMK-5204: An orally active β-1,3-glucan synthesis inhibitor, Synthetic Route of 7080-50-4, the publication is Bioorganic & Medicinal Chemistry Letters (2020), 30(17), 127357, database is CAplus and MEDLINE.

Our previously reported efforts to produce an orally active β-1,3-glucan synthesis inhibitor through the semi-synthetic modification of enfumafungin focused on replacing the C2 acetoxy moiety with an aminotetrazole and the C3 glycoside with a N,N-dimethylaminoether moiety. This work details further optimization of the C2 heterocyclic substituent, which identified 3-carboxamide-1,2,4-triazole as a replacement for the aminotetrazole with comparable antifungal activity. Alkylation of either the carboxamidetriazole at C2 or the aminoether at C3 failed to significantly improve oral efficacy. However, replacement of the iso-Pr α-amino substituent with a t-Bu, improved oral exposure while maintaining antifungal activity. These two structural modifications produced MK-5204, which demonstrated broad spectrum activity against Candida species and robust oral efficacy in a murine model of disseminated Candidiasis without the N-dealkylation liability observed for the previous lead.

Apgar, James M. published the artcileIbrexafungerp: An orally active β-1,3-glucan synthesis inhibitor, SDS of cas: 5034-06-0, the publication is Bioorganic & Medicinal Chemistry Letters (2021), 127661, database is CAplus and MEDLINE.

We previously reported medicinal chem. efforts that identified MK-5204 (I), an orally efficacious β-1,3-glucan synthesis inhibitor derived from the natural product enfumafungin. Further extensive optimization of the C2 triazole substituent identified 4-pyridyl as the preferred replacement for the carboxamide of MK-5204, leading to improvements in antifungal activity in the presence of serum, and increased oral exposure. Reoptimizing the aminoether at C3 in the presence of this newly discovered C2 substituent, confirmed that the (R) t-Bu, Me aminoether of MK-5204 provided the best balance of these two key parameters, culminating in the discovery of ibrexafungerp (II), which is currently in phase III clin. trials. Ibrexafungerp displayed significantly improved oral efficacy in murine infection models, making it a superior candidate for clin. development as an oral treatment for Candida and Aspergillus infections.
