Inhibin B on the day of HCG-administration is a predictive factor for failure in assisted reproduction cycles.

Materials And Methods: This retrospective study was carried out in order to assess the value of inhibin B as a predictive factor for the assisted reproduction-outcome. Inhibin B on the day of HCG-administration (ovulation induction) was measured in 15 pregnant and 16 non-pregnant patients (defined as positive serum-HCG) and compared by single and multiple logistic regression analysis with classical predictive factors such as estrogen and oocyte number. Both groups were similar with respect to age and cause of infertility.

Inhibin A/B in HMG or recombinant FSH ovarian stimulation with cetrorelix medication.

The inhibins are valuable factors in the assessment of the quality of an ovarian stimulation cycle. In spite of good clinical results with recombinant FSH and multiple dose LHRH- antagonist (Cetrotide((R))) administration, there remains a theoretical concern that in cycles stimulated with recombinant FSH, devoid of any LH activity, not enough endogenous LH is available to guarantee good follicle maturation. A total of 287 serum samples from 41 patients was assessed: 20 patients received ovarian stimulation with recombinant FSH, 21 patients with HMG and multiple dose Cetrotide administration.

2-aroylindoles, a novel class of potent, orally active small molecule tubulin inhibitors.

2-Aroylindoles with 5-methoxy-1H-2-indolyl-phenylmethanone (D-64131) as the lead structure were discovered as a new class of synthetic, small molecule tubulin inhibitors. By competitively binding with [(3)H]colchicine to alphabeta-tubulin and inhibiting microtubule formation, cycling cells were arrested in the G(2)-M phase of the cell division cycle. The proliferation of tumor cells from 12 of 14 different organs and tissues was inhibited with mean IC(50)s of 62 nM and 24 nM by D-64131 and D-68144, respectively, comparable with the potency of paclitaxel with mean IC(50) of 10 nM.
