17-Deoxoestrone [estra-1,3,5(10)-trien-3-ol]-methanol (3/1).

Project description:Three independent mol-ecules of the title estrone derivative and a mol-ecule of methanol comprise the asymmetric unit of the title compound [systematic name: 13-methyl-6,7,8,9,11,12,13,14,15,16-deca-hydro-cyclo-penta-[a]phenanthren-3-ol-meth-an-ol (3/1)], 3C(18)H(24)O·CH(3)OH. Two of the estrone mol-ecules exhibit 50:50 disorder (one displays whole-mol-ecule disorder and the other partial disorder in the fused five- and six-membered rings) so that five (partial) mol-ecular conformations are discernable. The conformation of the six-membered ring abutting the aromatic ring is close to a half-chair in all five components. The conformation of the six-membered ring fused to the five-membered ring is based on a chair with varying degrees of distortion ranging from minor to significant. Two distinct conformations are found for the five-membered ring: in four mol-ecules, the five-membered ring is twisted about the bond linking it to the six-membered ring, and in the other, the five-membered ring is an envelope with the quaternary C atom being the flap atom. The crystal packing features O-H?O hydrogen bonding whereby the four mol-ecules comprising the asymmetric unit are linked into a supra-molecular chain along the b axis.

Crystal structure of bis-[3-meth-oxy-17?-estra-1,3,5(10)-trien-17-yl] oxalate.

Project description:In the title compound, C40H50O6, a symmetrical steroid oxalate diester, the dihedral angle between the CO2 planes of the oxalate linker is 61.5?(5)° and the C-C bond length is 1.513?(6)?Å. The steroid B, C and D rings adopt half-chair, chair and envelope conformations, respectively, in both halves of the mol-ecule, which adopts an overall shallow V-shaped conformation.

Crystal structure of 16-ferrocenylmethyl-3?-hydroxy-estra-1,3,5(10)-trien-17-one: a potential chemotherapeutic drug.

Project description:A new ferrocene complex, 16-ferrocenylmethyl-3?-hy-droxy-estra-1,3,5(10)-trien-17-one dimethyl sulfoxide monosolvate, [Fe(C5H5)(C24H27O2)]·C2H6OS, has been synthesized and structurally characterized by single-crystal X-ray diffraction techniques. The mol-ecule crystallizes in the space group P21 with one mol-ecule of dimethyl sulfoxide. A hydrogen bond links the phenol group and the dimethyl sulfoxide O atom, with an O?O distance of 2.655?(5)?Å. The ferrocene group is positioned in the ? face of the estrone moiety, with an O-C-C-C torsion angle of 44.1?(5)°, and the carbonyl bond length of the hormone moiety is 1.216?(5)?Å, typical of a C=O double bond. The average Fe-C bond length of the substituted Cp ring [Fe-C(Cp*)] is similar to that of the unsubstituted one [Fe-C(Cp)], i.e. 2.048?(3) versus 2.040?(12)?Å. The structure of the complex is compared with those of estrone and eth-oxy-methyl-estrone.

Synthesis and Discovery of Estra-1,3,5(10),6,8-pentaene-2,16?-diol.

Project description:A metallacycle-centered approach to the assembly of partially aromatic synthetic steroids was investigated as a means to prepare a boutique collection of unique steroidal agents. The synthesis and discovery of estra-1,3,5(10),6,8-pentaene-2,16?-diol (VII) is described, along with structure-activity relationships related to its cytotoxic properties. Overall, VII was found to have a GI50 = 0.2 ?g/mL (?800 nM) in MDA-MB-231 human breast cancer cells, be an efficacious estrogen receptor agonist with potency for ER? > ER? (ER? EC50 = 21 nM), possess selective affinity to the cdc-2-like kinase CLK4 (Kd = 350 nM), and be phenotypically related to paclitaxel by an unbiased panel assessment.

Project description:In the title compound, C(13)H(15)NO(3)S, the sole classical hydrogen-bond donor is involved in an intra-molecular O-H?N hydrogen bond. In the crystal structure, pairs of mol-ecules related by inversion centres are linked by pairs of weak inter-molecular C-H?O inter-actions; these centrosymmetric pairs are, in turn, linked further by weak inter-molecular C-H?O inter-actions, forming two-dimensional sheets oriented parallel to (101).
