Medical device associated infections remain a significant problem for all classes of devices at this point in time. Here, we have developed a surface modification technique to fabricate multifunctional coatings that combine antifouling and antimicrobial properties. Zwitterionic polymers providing antifouling properties and quaternary ammonium containing polymers providing antimicrobial properties were combined in these coatings. Throughout this study, aminomalononitrile (AMN) was used to achieve one-step coatings incorporating different polymers. The characterization of coatings was carried out using static water contact angle (WCA) measurements, XPS, profilometry, and SEM, whereas the biol. response in vitro was analyzed using Staphylococcus epidermidis and Escherichia coli as well as L929 fibroblast cells. Zwitterionic polymers synthesized from sulfobetaine methacrylate and 2-aminoethyl methacrylate were demonstrated to reduce bacterial attachment when incorporated in AMN assisted coatings. However, bacteria in suspension were not affected by this approach. On the other hand, alkylated polyethylenimine polymers, synthesized to provide quaternary ammonium groups, were demonstrated to have contact killing properties when incorporated in AMN assisted coatings. However, the high bacterial attachment observed on these surfaces may be detrimental in applications requiring longer-term bactericidal activity. Therefore, AMN-assisted coatings containing both quaternary and zwitterionic polymers were fabricated. These multifunctional coatings were demonstrated to significantly reduce the number of live bacteria not only on the modified surfaces, but also in suspension. This approach is expected to be of interest in a range of biomedical device applications.

Ferris, J. P. published the artcileThe effect of clays on the oligomerization of hydrocyanic acid, Name: 2-Aminomalononitrile 4-methylbenzenesulfonate, the publication is Journal of Molecular Evolution (1979), 13(4), 317-30, database is CAplus and MEDLINE.

The possible role of clays in prebiotic evolution was studied using the primitive Earth model in which aqueous solutions of HCN and diaminomaleonitrile (I) react with clay mineral sediments. The reaction of 0.1M HCN and dilute solutions of I at pH 8-9 and 25° in the presence of suspensions of montmorillonite (bentonite) clays were investigated. Montmorillonite clays inhibited the oligomerization of aqueous solutions of HCN. Yields of colored oligomers, urea, and I were all diminished by clays, but the rate of loss of cyanide was not significantly decreased. The inhibition of oligomer formation was due to the clay-catalyzed decomposition of I. The absence of strong binding of I to clays was suggested by the failure to detect I when a clay that was incubated with I was washed with spermidine (6 × 10^-3 g/L). I did not simply bind to the clays as the bulk of radioactivity was recovered from the supernatant in the reaction of I–¹⁴C with montmorillonite. The clay-catalyzed decomposition of I was observed when montmorillonite from 2 different sources was used and with a variety of homoionic montmorillonites and bentonites. A modification of the established procedure for using the cyanide electrode for cyanide analyses was used to follow the release of HCN from I. This new method could be used in both the acidic and basic pH range and did not result in the destruction of I by the reagents used for the anal. Quant. anal. of the reaction solution from the clay-catalyzed decompositions of I revealed the formation of 1-2 equiv HCN/mol I. The possible significance of these clay-catalyzed reactions in prebiotic evolution is discussed.

Cristalli, Gloria published the artcileAdenosine deaminase inhibitors: synthesis and structure activity relationships of imidazole analogs of erythro-9-(2-hydroxy-3-nonyl)adenine, Quality Control of 5098-14-6, the publication is Journal of Medicinal Chemistry (1991), 34(3), 1187-92, database is CAplus and MEDLINE.

A series of erythro-1-(2-hydroxy-3-nonyl)imidazole derivatives were synthesized and evaluated for adenosine deaminase (ADA) inhibitory activity, in order to introduce simplifications in the ADA inhibitors erythro-9-(2-hydroxy-3-nonyl)adenine [EHNA, (I; X = N)] and 3-deaza-I (X = CH). Opening the pyrimidine or pyridine ring of I (X = N, CH), resp. led to compounds which are still ADA inhibitors. The most potent compound was erythro-1-(2-hydroxy-3-nonyl)imidazole-4-carboxamide (II; K_i = 3.53 × 10^-8 M), which provided potential donor and acceptor sites for hydrogen bonding. Lack of one of this sites could account for the order of potency of all compounds examined in this series. Opening the same ring in adenosine and in 3-deazaadenosine led to fully inactive compounds These results support the hypothesis of the existence, at or near the enzyme active site, of a hydrophobic region able to bind the erythro-nonyl moiety.

Shen, Yan published the artcileCopper-catalyzed direct C-H arylation of pyridine N-oxides with arylboronic esters: one-pot synthesis of 2-arylpyridines, HPLC of Formula: 214360-44-8, the publication is Chemical Communications (Cambridge, United Kingdom) (2014), 50(33), 4292-4295, database is CAplus and MEDLINE.

The first example of the copper-catalyzed direct C-H arylation of pyridine N-oxides with arylboronic esters has been developed, leading to a wide range of 2-arylpyridines in a one-pot synthesis with moderate to good yields without an addnl. reductant. This transformation allows for rapid access to a variety of 2-arylpyridines using an inexpensive catalytic system that would be more difficult to access with traditional methods. Thus, this method represents a simple and practical procedure to access 2-arylpyridines.

Rosowsky, Andre published the artcileMethotrexate analogs. 4. 7-Methyl derivatives of methotrexate and dichloromethotrexate. New synthesis and some biological studies, HPLC of Formula: 5098-14-6, the publication is Journal of Medicinal Chemistry (1974), 17(12), 1308-11, database is CAplus and MEDLINE.

Conversion of methotrexate (I) [59-05-2] and 3′,5′-dichloromethotrexate (II) [528-74-5] to their 7-methyl analogs III [35190-25-1] and IV [53729-18-3], resp., to prevent metabolism in vivo to the inactive 7-hydroxy derivatives resulted in marked loss of antileukemic activity in mice and in vitro and loss of inhibitory potency against purified dihydrofolate reductase [9002-03-3] from Lactobacillus casei and L1210-FR8 tumor. The lack of antitumor activity presumably resulted from impaired enzyme binding. III was prepared from 2-amino-5-chloromethyl-3-cyano-6-methylpyrazine 1-oxide [53661-20-4] and diethyl N-(p-N-methylaminobenzoyl)glutamate [2378-95-2] by the method of E. C. Taylor, et al. (1973).

Jeong, Susan published the artcileMacrocyclic Triarylethylenes via Heck Endocyclization: A System Relevant to Diazonamide Synthesis, COA of Formula: C10H11N3O3S, the publication is Journal of Organic Chemistry (1998), 63(24), 8640-8641, database is CAplus.

The author’s approach the preparation of diazonamide A (I) synthesis is described. Initial results show that Heck endocyclization can form highly functionalized lactam rings containing an imbedded 1,2-diaryl-1-(5-oxazolyl)ethylene. Thus, cross-coupling of vinylstannane II (PMB = p-methoxybenzyl) with functionalized oxazole III (prepared in 2 steps from Boc-Val-OH and aminomalononitrile tosylate) gave phenol IV in 89% yield after deprotection. Peptide coupling of IV with a protected O-benzyl-3-iodotyrosine derivative, followed by Pd-catalyzed macrocyclization gave macrocycle V, which contains the diazonamide AEF ring system.

Bai, Xueqian published the artcileSynthesis, antimicrobial activities, and molecular docking studies of dihydrotriazine derivatives bearing a quinoline moiety, Computed Properties of 612-13-5, the publication is Chemistry & Biodiversity (2019), 16(6), n/a, database is CAplus and MEDLINE.

In this article, three series of dihydrotriazine derivatives bearing a quinoline moiety (5a, 5b, 8a-8c, and 9a-9m) have been designed, synthesized, and evaluated as antibacterial agents. Compounds 8a-8c were found to be the most potent of all of the compounds tested with an MIC value of 1 μg/mL against several Gram-pos. (S. aureus 4220 and MRSA CCARM 3506) and Gram-neg. (E. coli 1924) strains of bacteria. In addition, 3-[4-amino-6-(phenethylamino)-2,5-dihydro-1,3,5-triazin-2-yl)-6-[(3-chlorobenzyl)oxy]quinolin-2-ol (8a) showed potent inhibitory activity (MIC=2 μg/mL) against Pseudomonas aeruginosa 2742, indicating that its antibacterial spectrum is similar to those of the pos. controls gatifloxacin and moxifloxacin. Structure-activity relationships (SAR) analyses and docking studies implicated the dihydrotriazine group in increasing the antimicrobial potency of the quinoline compounds In vitro enzyme study implied that compound 8a also displayed DHFR inhibition.
