High impact information on Mdl 28564

  • The pseudopeptide derivative of NKA(4-10), MDL 28,564 behaved as a full or near-to-full agonist in both preparations, its EC50s being 474 nM and 55 nM in the ileum and colon, respectively [1].
  • On the other hand, MDL 28,564 had an agonist effect in the isolated gallbladder, its maximal effect approaching 58% of that to NKA [2].
  • Contractile responses to neurokinin A (NKA), neuropeptide gamma(NP gamma), and the NK2 receptor-selective analogs [Lys5,MeLeu9,Nle10]NKA(4-10) and MDL 28,564 were determined in the endothelium-denuded rabbit pulmonary artery [3].
  • MDL 28,564 also produced full contraction in rabbit pulmonary artery (NK2 tissue) but was inactive in rat vas deferens (NK2 tissue) [4].
  • [Leu9 psi(CH2NH)Leu10]-neurokinin A (4-10) (MDL 28,564) distinguishes tissue tachykinin peptide NK2 receptors [4].
 

Anatomical context of Mdl 28564

 

Gene context of Mdl 28564

  • The pseudopeptide, MDL 28,564, which is one of the most selective NK2 ligands available, behaved as a full agonist [6].
