Conventional and Microwave-Activated the Synthesis of a Novel Series of Imidazoles, Pyrimidines, and Thiazoles Candidates

A novel series of imidazoles, pyrimidines, and thiazoles were synthesized using microwave irradiation and conventional method from commercial available p-aminobenzoic acid. Thus, one-pot condensation of p-aminobenzoic acid, urea, and chloroacetic acid have been provided two types of imidazole derivatives as separated mixture 2a and 2b. [3?+?2?+?1] Cyclocondensation of 2a, benzaldehyde, and urea/thiourea in acidic medium afforded imidazolo oxazine derivative 3 and Imidazolothiazine 4. Coupling of 2a with benzene diazonium salt gave the phenyldiazenyl imidazolidine 5. While the reaction of 2a, thiourea, and benzaldehyde in sodium ethoxide afforded imidazolothiazine 6. Oxidative cyclization of thiourea derivative 7 resulted a mixture of benzithiazole derivative 7a and oxathiazole derivative 7b. Cyclocondensation of 7a with phenylenediamine and 4-methyl phenylenediamine furnished imidazole 8 and 9, respectively. Reaction of P-aminobenzioc acid with potassium cyanate followed by Biginelli reaction with (acetyl acetone, ethyl acetoacetate, and diethyl malonate) and salicyladehyde in HCl tolerated pyrimidine derivatives 10a–c, respectively. In the same manner, the reactions and short reaction time make microwave technique one of the greenest methodology for synthesis of this class of heterocyclic system.

Facile synthesis of some condensed 1,3-thiazines and thiazoles under conventional conditions: antitumor activity

1,3-Thiazine 3 was obtained from cinnamoyl thiourea derivative 2 as the kinetic control product. Refluxing of 2 with sodium ethoxide afforded pyrimidine derivative 4. Moreover, stirring of 2 with bromine/acetic acid gave thiazole 5 that was condensed with o-phenylene diamine forming benzimidazole 6. Heating of arylthiourea 8 with maleic anhydride or phenacyl chloride afforded thiazole derivatives 9 and 10, respectively. Condensation of compound 10 with o-phenylene diamine gave benzimidazole 11. Reaction of p-amino benzoic acid with chloro acetyl isothiocyanate, acetylacetone and ethylacetoacetate produced imidazole 14, enaminone 15 and crotonate 16 derivatives, respectively. Stirring a mixture of benzoyl isothiocyanate with 15 and/or 16 resulted in pyridine-2-thione 17. The yields of the prepared compounds were 41–93%. The experimental section is simple and easy. The detailed synthesis, spectroscopic data, IC50 and antitumor activity of the synthesized compounds were reported. The cytotoxicity of the newly synthesized products showed that compound 4 is the most active compound towards the cancer cell line at which its reactivity is higher than that of the standard doxorubicin (anticancer reference drug).

Synthesis and in-vitro evaluation of 2-amino-4-arylthiazole as inhibitor of 3D polymerase against foot-and-mouth disease (FMD)

Foot-and-mouth disease (FMD) is a highly contagious vesicular disease of livestock caused by a highly variable RNA virus, foot-and-mouth disease virus (FMDV). One of the targets to suppress expansion of and to control FMD is 3D polymerase (FMDV 3Dpol). In this study, 2-amino-4-arylthiazole derivatives were synthesized and evaluated for their inhibitory activity against FMDV 3Dpol. Among them, compound 20i exhibited the most potent functional inhibition (IC50 = 0.39μM) of FMDV 3D polymerase and compound 24a (EC50=13.09 μM) showed more potent antiviral activity than ribavirin (EC50=1367 μM) and T1105 (EC50=347 μM) with IBRS-2 cells infected by the FMDV O/SKR/2010 strain.

Substituted N-phenylisothioureas: Potent inhibitors of human nitric oxide synthase with neuronal isoform selectivity

S-Ethyl N-phenylisothiourea (4) has been found to be a potent inhibitor of both the human constitutive and inducible isoforms of nitric oxide synthase. A series of substituted N-phenylisothiourea analogues was synthesized to investigate the structure-activity relationship of this class of inhibitor. Each analogue was evaluated for human isoform selectivity. One analogue, S-ethyl N-[4-(trifluoromethyl)phenyl]isothiourea (39), exhibited 115-fold and 29-fold selectivity for the neuronal isoform versus the inducible and endothelial derived constitutive isoforms, respectively. Studies have shown the substituted N-phenylisothiourea 39 binds competitively with L,-arginine.
