Eight novel N-(2-aminophenyl)-2-quinazolinone-acetamide hydrochloride were synthesized and their structures were identified by 1H NMR, MS and IR spectra. Seven of the new compounds were chosen for anticoccidial activity test and the results showed that N-(2- aminophenyl)-2-(6-methyl-8-bromo quinazolinone) acetamide hydrochloride (3h) exhibited anticoccidial activity against Eimeria tenella in the chicken' diet with a dose of 18 mg/Kg.

Some novel benzimidazole-tethered 1,2,3-triazole derivatives (4a–r) were synthesized by a click reaction between 2-substituted 1-(prop-2-yn-1-yl)-1H-benzo[d]imidazole and in situ azide. The structures of the synthesized compounds were confirmed by spectroscopic studies (one- and two-dimensional nuclear magnetic resonance, Fourier transform infrared, and high-resolution mass spectra). The synthesized compounds were evaluated for their antidiabetic activity. Compounds 4a–r exhibited a good-to-moderate α-amylase and α-glucosidase inhibitory activity, with IC50 values ranging from 0.0410 to 0.0916 μmol/ml and 0.0146 to 0.0732 μmol/ml, respectively. Compounds 4e, 4g, and 4n were found to be most active. Furthermore, the binding conformation of the most active compounds was ascertained by docking studies.

supporting information, p. 8085 - 8090 (2019/10/14)
Herein we present a library of simple amide derivatives of Cinchona alkaloids in the form of quaternary ammonium salts. The obtained derivatives can be generated very easily and efficiently from inexpensive and commercially available substrates. We tested this class of alkaloids in the alkylation of glycine derivative, carried out under phase-transfer catalyst conditions. The presented hybrid catalysts offer both high reaction yields (up to 97%) and high enantioselectivities of the obtained product (up to 94% ee).
Synthesis, crystal structure and antimicrobial activity of 2-((2-(4-(1H-1,2,4-triazol-1-yl)phenyl)quinazolin-4-yl)oxy)-N-phenylacetamide derivatives against phytopathogens

Abstract: A total of eighteen 2-((2-(4-(1H-1,2,4-triazol-1-yl)phenyl)quinazolin-4-yl)oxy)-N-phenylacetamide derivatives were designed and synthesized, via hybrid pharmacophore approach. Among these compounds, chemical structure of compound 4a was unambiguously confirmed by means of single-crystal X-ray diffraction analysis. All the compounds were evaluated in vitro for their inhibition activity against several important phytopathogenic bacteria and fungi in agriculture. The obtained results indicated that several compounds demonstrated potent antibacterial activity against Xanthomonas oryzae pv. oryzae (Xoo). For example, compounds 4c, 4g and 4q had EC50 values of 35.0, 36.5 and 32.4 μg/mL toward this bacterium, respectively, around 1.5 times more active than commercial bactericide bismerthiazol (EC50 = 89.8 μg/mL). Additionally, compounds 4j and 4p were found to display comparable antifungal activity against Gloeosporium fructigenum at 50 μg/mL, to commercial fungicide hymexazol. Finally, the relationships between antibacterial activities and molecular structures of this class of compounds were discussed in detail. Graphical abstract: [Figure not available: see fulltext.].

Synthesis of novel 1,2,4-triazole derivatives containing the quinazolinylpiperidinyl moiety and: N -(substituted phenyl)acetamide group as efficient bactericides against the phytopathogenic bacterium Xanthomonas oryzae pv. oryzae

A series of novel 1,2,4-triazole derivatives (7a-7p) containing the quinazolinylpiperidinyl moiety and N-(substituted phenyl)acetamide group were designed, synthesized and evaluated for their antimicrobial activities in vitro. These compounds were fully characterized by 1H NMR, 13C NMR, HRMS and IR spectra. Notably, the structure of compound 7p was further confirmed through the single-crystal X-ray diffraction method. The obtained bioassay results indicated that most of these compounds exhibited good to excellent antibacterial activities against the rice bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo). For example, compounds 7e, 7g, 7n, 7l, 7i, 7k, 7a and 7h had EC50 (half-maximal effective concentration) values of 34.5, 38.3, 39.0, 46.0, 47.5, 54.6, 55.0 and 58.2 μg mL-1 against the bacterium, respectively, which were significantly lower than the control agent Bismerthiazol (85.6 μg mL-1). Additionally, antifungal experiments demonstrated that all the compounds did possess weak inhibition capabilities against three phytopathogenic fungi at 50 μg mL-1, except in the cases of compounds 7e and 7p against the fungus Gibberella zeae. The above experimental results proved that 1,2,4-triazole derivatives bearing both a quinazolinylpiperidinyl fragment and N-(substituted phenyl)acetamide unit are promising candidates for the development of new agricultural bactericides against the pathogenic bacterium Xoo, deserving further investigation in the future.

2-(Quinolin-4-yloxy)acetamides have been described as potent in vitro inhibitors of Mycobacterium tuberculosis growth. Herein, additional chemical modifications of lead compounds were carried out, yielding highly potent antitubercular agents with minimum inhibitory concentration (MIC) values as low as 0.05 μM. Further, the synthesized compounds were active against drug-resistant strains and were devoid of apparent toxicity to Vero and HaCat cells (IC50s ≥ 20 μM). In addition, the 2-(quinolin-4-yloxy)acetamides showed intracellular activity against the bacilli in infected macrophages with action similar to rifampin, low risk of drug-drug interactions, and no sign of cardiac toxicity in zebrafish (Danio rerio) at 1 and 5 μM. Therefore, these data indicate that this class of compounds may furnish candidates for future development to, hopefully, provide drug alternatives for tuberculosis treatment.
