Source of material

30 ml of ethanolic solution of (E)-3-(4-florophenyl)-1-(4-hydroxyphenyl) prop-2-en-1-one (1.00 mmol) and 4-hydrazinobenzenesulfonamide hydrochloride (1.10 mmol) in presence of catalytic amount of glacial acetic acide was refluxed for 11 h. The contents of reaction was monitored by TLC. The mixture was stirred at room temperature for 12 h. The solvent was removed under vacuum pump. The solid obtained was crystallized from methanol-ether [1].

Experimental details

Carbon-bound H-atoms were positioned geometrically (C—H = 0.93–0.98 Å) and were included in the refinement in the riding model approximation, with Uiso(H) = 1.2 Ueq(C). The H atoms bonded to N3 and the hydroxyl H atom bonded to O1 were located in a difference Fourier map and treated as riding atoms with Uiso(H) = 1.2 Ueq(N) for the NH2 group and Uiso(H) = 1.5 Ueq(O) for the hydroxyl group. The absolute structure was determined [22] from 1726 Friedel pairs. The Flack parameter refines to a value of 0.04(2) [19].

Discussion

Pyrazolines are prominent nitrogen containing five membered heterocyclic compounds possessing broad spectrum of bioactivities such as antimicrobial [2, 3], antiinflammatory [4], antitubercular and anelgesic [5], LDL-oxidation inhibitor [6], antidepresant [7] activities.

Medicinally important pyrazoline derivatives are 1,3,5-trisubstituted pyrazolines. There are several studies reporting their bioactivities such as antimicrobial, antiinflammatory [1, 8], blood glucose lowering activity or antidiabetic [8], selectivite COX-2 inhibition [9], dipeptidyl peptidase-IV (DP—IV) inhibition [10] activities.

Coumarin bearing 2-pyrazoline hybrids endowed with phenylsulfonyl moiety presented antitumor activity [11]. Anti- inflammatory and anticancer activities of 2-pyrazoline bearing benzene sulfonamides were reported [12, 13].

In the title structure (Fig.). The pyrazole ring (N1/N2/C7–C9) exhibits an envelope conformation [the puckering parameters [14] are Q(2) = 0.150(3) Å and φ(2) = 76.5(9)°], with the methine C9 atom being the flap atom. The central pyrole ring makes dihedral angles of 8.33(12), 87.06(13) and 7.27(12)°, respectively, with the hydroxy- and fluoro-benzene rings (C1–C6 and C10–C15) and the benzenesulfonamide ring (C16–C21).

The bond lengths and bond angles in the title compound are normal and are almost similar to those reported earlier for the related structures [15, 16].

In the benzenesulfonamide group, the sulfonamide oxygen atom O3 is involved in an intramolecular C—H⋯O hydrogen bond with C18, forming a S(5) ring [17]. The crystal structure is stabilized by intermolecular N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds and C—H⋯π interactions, forming a three dimensional network.
