The title complex(C66H76O8·CH3CN) was synthesized and structurally determined by single-crystal X-ray diffraction method. It crystallizes in monoclinic, space group P21/c with a = 22.384(13), b = 13.413(7), c = 21.867(12), β = 112.257(7)°, C68H78NO8, Mr = 1037.31, Dc = 1.133 g/cm3, V = 6076(6) 3, Z = 4, F(000) = 2224, μ(MoKa) = 0.073 mm-1, T = 296(2) K, 10276 independent reflections with 5469 observed ones(I 〉 2σ(I)), R = 0.0797 and wR = 0.2316 with GOF = 1.027(R = 0.1442 and wR = 0.2689 for all data). The calixarene moiety maintains the symmetric cone conformation through intramolecular O–H···O hydrogen bonds. The inhibition of the strand transfer process of HIV-1 integrase of the title compound was also evaluated. Preliminary bioassays indicated that it has a low inhibition ratio(24.85%) at the concentration of 50 μM.
The title compound (C50H.44010) was synthesized and structurally determined by single-crystal X-ray diffraction method. It crystallizes in monoclinic, space group P21/c with a = 16.713(4), b --- 13.189(3), c = 19.434(5) A, β = 104.411(4)°, Mr = 804.85, Dc = 1.288 g/cm3, V = 4149.2(17) A3, Z = 4, F(000) = 1696, #(MoKa) = 0.089 mm-1T = 296(2) K, 7279 independent reflections with 3172 observed ones (I 〉 2δ(/)), R = 0.0520 and wR = 0.1203 with GOF = 0.928 (R = 0.1464 and wR = 0.1657 for all data). The calixarene moiety maintains the symmetric cone conformation through intramolecular O-H…O hydrogen bonds. Preliminary bioassays indicated that the title compound has a potent inhibitory activity against the strand transfer process of HIV-1 integrase.
The target compound (C58H74N6010) has been structurally determined by single- crystal X-ray diffraction. The crystal is in the monoclinic system, space group C2/c, with a = 22.08(3), b = 12.628(19), c- 21.73(3)A, β= 106.78(3)°, C58H74N6010, Mr= 1015.23, Dc = 1.16239 g/cm^3, V = 5801(14) A3, Z = 4, F(000) = 2176, μ(MoKa) = 0.080 mm^-1, T = 293(2) K, 5107 independent reflections with 3125 observed ones (1〉 20(I)), R = 0.0768 and wR = 0.2305 with GOF = 1.025 (R = 0.1129 and wR = 0.2674 for all data). The calixarene moiety maintains the symmetric cone conformation through intramolecular O-H…O and N-H…O hydrogen bonds. The thermal analysis showed that the decomposition mechanism of compound 3 is complex. Fluorescence spectra of 3 exhibited an emission band at 423 nm when excited with 360 nm radiation at room temperature in DMF.
