High impact information on ZK 98299

  • The antiprogestins RU 486 and ZK 98299 do not promote binding of the progesterone receptor to this natural HRE in vivo, even at concentrations that completely inhibit the agonistic effects of potent synthetic progestins [1].
  • We show here that RU 486 and ZK 98299 have the same effects on receptor activation, dimerization, and binding to hormone responsive elements; differences in their action are explained by the 10-fold difference in their affinity for the receptor (ZK 98299 having the lower affinity) [2].
  • The inhibition of P4 action by OP increased the expression of Fas mRNA (P <0.01); however, it did not affect bax or bcl-2 mRNA expression (P >0.05) [3].
  • Moreover, OP stimulated expression of caspase-3 mRNA (P <0.01) [3].
  • Luteal cells obtained from the cows in the midluteal phase of the estrous cycle (Days 8-12 of the cycle) were exposed to a specific P4 antagonist (onapristone [OP], 10(-4) M) with or without 100 ng/ml Fas L [3].

Associations of ZK 98299 with other chemical compounds

  • These compounds were tested for their binding affinity to various steroid receptors and for their bio-activity in various animal models and the results were compared with those of RU38486 and ZK 98299 [7].
