KEYWORDSThis article presents our research concerning the synthesis of new thiophene-thiourea derivatives (1-12) and their pharmacological properties. These novel thiophene-thiourea derivatives were synthesized and characterized by IR, 1 H and 13 C NMR spectroscopy, mass spectrometry and elemental analysis. The crystal structure of N,N-diphenyl-N'-(thiophene-2carbonyl)-thiourea was determined from single crystal X-ray diffraction data. It crystallizes in the monoclinic space group P21 with unit cell dimensions of a=11.7469(5) Å, b=6.0849(2) Å, c=12.5792(6) Å, β= 117.736(7) ° and V = 795.8(6) Å 3 . The mass fragmentation pattern has also been discussed. The synthesized compounds were screened for their in vitro antifungal activities against the standard strains: C. Albicans, C. Glabrata, and C. Tropicalis. The compounds N-
