Background: To highlight the magnitude of the important challenge now facing scientists, drug resistance needs exploration of novel antimicrobial agents. The identification of new and vital target in bacteria and then designing their inhibitors can be explored. Thus, targeting SecA, a central component of the bacterial general secretion system, is a promising strategy for the development of novel antimicrobials. Objective: To evaluate new compounds as SecA inhibitors synthesized by structural modification of bistriazole SCA-21. Method: A new compounds were synthesized and evaluated for antibacterial activity against Escherichia coli NR698 (E. coli a leaky mutant), Staphylococcus aureus (S. aureus) and Bacillus anthracis (B. anthracis). Results: Some novel triazole-pyrimidine derivatives by structural modification of known SecA inhibitor SCA 21 were synthesized and their structures were confirmed by 1H NMR, 13C NMR and Mass spectral anal. The synthesized compound showed antimicrobial activity against E. coli NR698 (a leaky mutant), S. aureus and B. anthracis Sterne. Conclusion: Five novel triazole-pyrimidine derivatives were designed, synthesized and evaluated as SecA inhibitors. At the end of this study, compound SCA 259 with azide pentyl group was found as the most potent inhibitor. It expressed better inhibitory activity against SecA ATPase than else known inhibitor SCA 21.

Treatment of 1 equivalent EtOH:C(CN)CO2Et(I) with 3 equivalents MeC(:NH)NH2 (II) in cold EtOH and maintaining the mixture at 0° 18 hrs. yielded 85.5% 5-cyano-4-hydroxy-2-methylpyrimidine acetamidinate (III, R = Me) (IV), m. 184-8° (EtOAc). Use of 2 or 1 equivalent II decreased the yields of IV to 69.0 and 20.3%, resp. A small amount of ethyl 4-amino-2-methyl-5-pyrimidinecarboxylate (V) was extracted from the reactions mixtures with Et2O. IV neutralized with AcOH gave 5-cyano-4-hydroxy-2-methylpyrimidine, reconverted to IV by treating with an equimolar amount of II in alc. The mass spectrum of IV revealed the strong parent ions m/e 135, 58 but no mol. ion, m/e 193, corresponding to N-(3-acetamidino-2-cyanoacryloyl)acetamidine, H2NCR:NCH:C(CN)CONHCR:-NH (VI, R = Me) (VII). The reactions of I with 2-ethyl-2-thiopseudourea (VIII) in MeOH readily gave Et 3-[[amino-(ethylthio)methylene]amino]-2-cyanoacrylate (IX); III (R = EtS) (X), m. 175-7°; and traces of V. Increase of the ratio of VIII to I from 1:1 to 4:1 led to decrease of the % yield of IX and increase of X. The reactions of guanidine with I in cold alc. gave predominantly Et 2,4-diamino-5-pyrimidinecarboxylate (XI), m. 215-17° (alc.), along with a trace of III (R = NH2) (XII), m. >300° (MeOH), converted to 2-amino-5-cyano-4-hydroxypyrimidine, m. >300° (AcOH), by treating with AcOH.

The author of the article were Al-Ali, Hassan; Schurer, Stephan C.; Lemmon, Vance P.; Bixby, John L.. The article conveys some information:

A fundamental impediment to functional recovery from spinal cord injury (SCI) and traumatic brain injury is the lack of sufficient axonal regeneration in the adult central nervous system. There is thus a need to develop agents that can stimulate axon growth to re-establish severed connections. Given the critical role played by protein kinases in regulating axon growth and the potential for pharmacol. intervention, small mol. protein kinase inhibitors present a promising therapeutic strategy. Here, the authors report a robust cell-based phenotypic assay, utilizing primary rat hippocampal neurons, for identifying small mol. kinase inhibitors that promote neurite growth. The assay is highly reliable and suitable for medium-throughput screening, as indicated by its Z’-factor of 0.73. A focused structurally diverse library of protein kinase inhibitors was screened, revealing several compound groups with the ability to strongly and consistently promote neurite growth. The best performing bioassay hit robustly and consistently promoted axon growth in a postnatal cortical slice culture assay. This study can serve as a jumping-off point for structure activity relationship (SAR) and other drug discovery approaches toward the development of drugs for treating SCI and related neurol. pathologies.

The information in the text is summarized as follows:

Some novel 4,4′-bis(2,4-pyrimidinyl)-diamino stilbene-2,2′-disulfonic acid derivatives 4a-d were designed and synthesized. Their structures were confirmed by proton NMR, elemental anal. and UV absorption spectra. All newly synthesized compounds were interrogated on their whitening effect on cotton fiber as fluorescent whitening agents. Their optical properties were evaluated by the degree of whiteness, color index, light fastness, wet rubbing fastness and dry rubbing fastness. The results indicated that compounds 4a-d showed an obvious whitening effect on cotton fiber and higher fastness than that of C186. The reflectivity of cotton fiber treated with compounds 4a-d at the critical concentration was up to 120.76%. In contrast, the reflectivity of untreated cotton fiber was only 87.23%. The UV absorption properties of compound 4d were tested under diverse pH values. The results showed that the UV absorption intensity of compound 4d decreased significantly and the absorption curve had blue shift under acidic conditions. Compound 4d was found to be the most effective mol. as a fluorescent whitening agent with a higher degree of whiteness (CIE Whiteness 135.04) compared to untreated cotton fiber (CIE Whiteness 73.02) at the critical concentration (0.1%).

Autoreactive B cell-derived antibodies form immune complexes that likely play a pathogenic role in autoimmune diseases. In systemic lupus erythematosus (SLE), these antibodies bind Fc receptors on myeloid cells and induce proinflammatory cytokine production by monocytes and NETosis by neutrophils. Bruton′s tyrosine kinase (BTK) is a non-receptor tyrosine kinase that signals downstream of Fc receptors and plays a transduction role in antibody expression following B cell activation. Given the roles of BTK in both the production and sensing of autoreactive antibodies, inhibitors of BTK kinase activity may provide therapeutic value to patients suffering from autoantibody-driven immune disorders. Starting from an inhouse proprietary screening hit followed by structure-based rational design, we have identified a potent, reversible BTK inhibitor, BIIB068 (1)(I), which demonstrated good kinome selectivity with good overall drug-like properties for oral dosing, was well tolerated across preclin. species at pharmacol. relevant doses with good ADME properties, and achieved >90% inhibition of BTK phosphorylation (pBTK) in humans.2,4-Dichloropyrimidine(cas: 3934-20-1Application of 3934-20-1) was used in this study.

The article was titled 《A bisimidazolium-based cationic covalent triazine framework for CO2 capture and dye adsorption》.Application of 1193-21-1 The article contains the following contents:

In this work, an aromatic nitrile containing the pyrimidine moiety and bisimidazolium cations (PyImCl) was synthesized and subsequently employed to prepare a bisimidazolium-based cationic covalent triazine framework (PyImCl-cCTF) through the ionothermal trimerization reaction. The chem. composition and structure of PyImCl-cCTF were carefully revealed by a series of techniques. As examined by N2 sorption isotherms at 77 K, PyImCl-cCTF exhibited large surface area and abundant microporous structures. Together with the high content of imidazolium cations derived from the bisimidazolium-based monomer, PyImCl-cCTF showed high CO2 uptake capacity of 235 and 133 mg/g at 1 bar under 273 and 298 K, resp., superior to the previously reported cCTFs. The dye adsorption performance of PyImCl-cCTF was performed for commonly used dyes. Surprisingly, PyImCl-cCTF exhibited a certain removal effect on both anionic and cationic dyes. Moreover, PyImCl-cCTF with the pos. charged skeleton can quickly remove anionic dyes through electrostatic interactions, showing almost 100% removal efficiency within 20 min. These results demonstrate that PyImCl-cCTF can behave as an efficient adsorbent for both CO2 capture and dye removal to solve environmental problems.4,6-Dichloropyrimidine(cas: 1193-21-1Application of 1193-21-1) was used in this study.

The author of the article were Srinivas, Doddipatla; Kawade, Monali; Upadhyaya, Hari P.. The article conveys some information:

The dynamics of chlorine atom (2Pj) formation in the photodissociation process of halogen substituted pyrimidines, namely, 2,4,6-trichloropyrimidine and 5-chloro-2,4,6-trifluoropyrimidine have been studied around 235 nm using Resonance Enhanced Multiphoton Ionisation Time-of-Flight Mass Spectrometry technique. For the chlorine atom dissociation channel, we have determined the translational energy distribution, the recoil anisotropy parameter, β, and the spin-orbit branching ratio. In both the mols., the TOF profiles for Cl (2P3/2) and Cl* (2P1/2) are found to be independent of laser polarisation suggesting a zero value for β, within the exptl. uncertainties. For 2,4,6-trichloropyrimidine, the average translational energies for Cl and Cl* elimination channels are determined to be 6.0 ± 1.2 and 7.0 ± 1.5 kcal/mol, resp. Similarly, for 5-chloro-2,4,6-trifluoropyrimidine, the average translational energies for Cl and Cl* elimination channels are determined to be 6.5 ± 1.2 and 7.9 ± 1.6 kcal/mol, resp. Computational calculations are performed to generate the potential energy curves along the dissociating C-Cl bond using equation of motion coupled cluster with single and double excitations (EOM-CCSD) method.
