5-Aryl-2-furaldehydes, obtained by furfural arylation with arenediazonium salts, react with ethyl acetoacetate or acetylacetone and (thio)- urea in the presence of FeCl3·6H2O as a catalyst. A series of ethyl 4-(5-aryl-2-furyl)-6-methyl-2-oxo(thioxo)-1,2,3,4-tetrahydropyrimidine- 5-carboxylates was obtained.

A series of dihydropyridines were prepared from the multi-component reaction of 5-arylfuran-2-carbaldehydes, ethylacetoacetate and ammonium acetate. These compounds were characterized through elemental analysis and various spectroscopic techniques (FTIR, 1H NMR, 13C NMR and mass).

Protein arginine methyltransferase 5 (PRMT5) is an important protein arginine methyltransferase that catalyzes the symmetric dimethylation of arginine resides on histones or non-histone substrate proteins. It has been thought as a promising target for many diseases, particularly cancer. Despite the potential applications of PRMT5 inhibitors in cancer treatment, very few of PRMT5i have been publicly reported. In this investigation, virtual screening and structure–activity relationship studies were carried out to discover novel PRMT5i, which finally led to the identification of a number of new PRMT5i. The most active compound, P5i-6, exhibited a considerable inhibitory potency against PRMT5 with an IC50 value of 0.57?μm, and a high selectivity for PRMT5 against other tested PRMTs. It displayed a very good antiviability activity against two colorectal cancer cell lines, HT-29 and DLD-1, and one hepatic cancer cell line, HepG2, in a sensitivity assay against 36 different cancer cell lines. Western blot assays indicated that P5i-6 selectively inhibited the symmetric dimethylations of H4R3 and H3R8 in DLD-1 cells. Overall, P5i-6 could be used as a chemical probe to investigate new functions of PRMT5 in biology and also served as a good lead compound for the development of new PRMT5-targeting therapeutic agents.

Phenotypic HTS campaigns with a blood stage malaria assay have been used to discover novel chemotypes for malaria treatment with potential alternative mechanisms of action compared to existing agents. N1-(5-(3-Chloro-4-fluorophenyl)furan-2-yl)-N3,N3-dimethylpropane-1,3-diamine, 1 was identified as a modest inhibitor of P. falciparum NF54 (IC50= 875 nM) with an apparent long plasma half-life after high dose oral administration to mice, although the compound later showed poor metabolic stability in liver microsomes through ring- and side chain-oxidation and N-dealkylation. We describe here the synthesis of derivatives of 1, exploring the influence of substitution patterns around the aromatic ring, variations on the alkyl chain and modifications in the core heterocycle, in order to probe potency and metabolic stability, where 4k showed a long half-life in rats.

A Pd/PCy3/Ag2CO3 (Cy = cyclohexyl) catalytic system was found to promote decarboxylative arylation through the combination of decarboxylation and C-H bond functionalization. This protocol features a good substrate scope of

A series of 4-arylidene-2-methyloxazol-5-ones 1 were condensed with thiosemi-carbazide to yield 6-arylmethyl-3-mercapto-1,2,4-triazin-5-ones 2. The resulting mercapto triazinones 2 were condensed with monochloroacetic acid and 5-aryl-furan-2-carboxaldehydes 3 in a one-pot three-component reaction in the presence of acetic anhydride, acetic acid, and sodium acetate to yield 4-substituted-5-oxo-7-(5-aryl-2-furfurylidene)-1,2,4-triazino[3,4-b] -thiazol-6-ones 4. Some of the newly synthesized compounds were tested for their antibacterial activity against Gram (+)ve and Gram (-)ve bacteria. The results of such studies are discussed in this paper.

A series of 5-phenyl-2-furamidines has been synthesized and evaluated for antidepressant activities. Substitution in the phenyl ring with a nitro (4) or an amino (12) group in the ortho-position resulted in an increase in antidepressant activity. Both 4 and 12 antagonized tetrabenazine-induced ptosis in rodents and inhibited norepinephrine (noradrenaline) uptake into crude synaptosomes of whole mouse brain at doses or concentrations comparable to those of the tricyclic antidepressants. However, these compounds did not possess the anticholinergic and antihistaminic activities common to tricyclic antidepressants. In addition, they lacked monoamine oxidase inhibitory activity. The 5-phenyl-2-furamidines represent a new chemical class of antidepressants and may be useful for depressive patients who cannot tolerate the compromising side effects of the tricyclic antidepressants and monoamine oxidase inhibitors.
