Jinbing Liu et al.
Bioorganic & medicinal chemistry, 16(3), 1096-1102 (2008-03-08)
A series of 1-(1-arylethylidene)thiosemicarbazide compounds and their analogues were synthesized and characterized by 1H NMR, MS. Their tyrosinase inhibitory activities were investigated by an assay based on the catalyzing ability of tyrosinase for the oxidation of L-DOPA, comparing with 4-methoxycinnamic
Mostafa M Ghorab et al.
Acta pharmaceutica (Zagreb, Croatia), 64(4), 419-431 (2014-12-23)
A novel series of thiophenes having biologically active sulfonamide 2-11, 3-methylisoxazole 12, 4-methoxybenzo[d] thiazole 13, quinoline 14, 15, benzoylphenylamino 16, and anthracene-9,10-dione 17 moieties were prepared. Structures of the newly synthesized compounds were established by elemental analysis and spectral data.
