Definitions
- the present invention relates to new peptides, processes for their preparation and their use in combating diseases.
- ion channel blockers have been used as antiarrhythmics which block transmembrane ion channels (sodium channels, calcium channels and / or potassium channels) which are suitable for therapy of acute cardiac arrhythmias which already exist.
- a new principle is the improvement of cellular coupling.
- An antiarrhythmic peptide AAP10 was proposed as a new principle (Naunyn Schmiedeberg's Arch. Pharmacol. 350, 174 (1994)), which leads to improved cellular coupling, local differences in the action potential duration reduced and the epicardial excitation patterns stabilized.
- this substance shows practically no proarrhythmic risk, but it is effective against ischemia-associated arrhythmias.
- the primary effect of the substance is to reduce the dispersion of the potential duration.
- the invention relates to the compounds of the formula I.
- X preferably denotes a glycine residue.
- Y is preferably a proline residue.
- Z is in particular a halogen atom, preferably iodine, which is in the 2- and preferably in the 3-position.
- the compounds I can be prepared by the methods customary in peptide chemistry. The following processes are particularly suitable for the production thereof:
- Solid phase synthesis on insoluble resins by a modified Merrifield method according to E. Atherston & R.C. Streppard (1989; "Solid phase peptide synthesis, IRL-Press, Oxford) using the Fmoc strategy.
- the amino acid activation can take place via the formation of acid anhydrides, 1-hydroxybenzotriazole esters or pentafluorophenyl esters.
- the invention allows prophylactic therapy of ischemia-associated and age-associated cardiac arrhythmias.
- the substances have no significant proarrhythmic risk in an in vitro experiment.
- the new peptides show a higher potency and a higher achievable maximum effect.
- tyrosine and phthalic anhydride were reacted with one another in glacial acetic acid for 20 h, and the reaction product was reacted with iodine and Hg (II) acetate to give N-phthalyl-L-monoiodtyrosine.
- the protective group was then cleaved off with phenylhydrazine.
- the reaction product was reacted with fluorenylmethoxycarbonyl-N-hydroxysuccinimide in the presence of Na 2 CO 3 , water and acetone. After acidification with HC1, the desired Fmoc iodine tyrosine was obtained.
- Fmoc-proline-OH was combined with 0- ((1H-benzotriazole-1-yD-NNNN-tetramethyluromi- num-tetrafluoroborate (TBTU), 1-hydroxybenzotriazole (HOBT), diisopropylethylamine (DIPEA) in DMF with the peptide
- the protective group was again split off with piperidine, DMF and, after further rinsing, the reaction product was reacted with Fmoc-hydroxyproline-OH as described above.
- OH and Fmoc-Glycino-OH were coupled in.
- the protective group was cleaved with 20% piperidine in DMF, rinsed and added for 6 h
- the peptide (1) was intracoronary to isolated rabbit hearts perfused with constant pressure (70 cm H 2 O) perfused with Tyrode's solution using the Langendorff technique (10 ⁇ 10 ,
- Table 1 Concentration-dependent effect on the dispersion of the epicardial potential duration under the antiarrhythmic peptide AAP10 and the new peptide.
- the better effect of the new peptide becomes particularly clear when one considers the number of values for the epicardial potential duration (ARI) which deviate from the mean value by less than 5 ms.
- the new peptide under control conditions was 54%, on the other hand already 10 " 10 mol / 1 71%, 10" 9 mol / 1 73%, 10 " ⁇ mol / 1 75% 10 " 7 mol / 1 up to 90% of the ARI values in the interval + 5 ms around the mean.
- AAP10 values were achieved over 70% only at concentrations above 10 "8 mol / 1, wherein a maximum of 74% was not th überschrit ⁇ .
- the new substance shows an effect compared to AAP10 even at a lower concentration and a greater maximum achievable effect of up to 90% compared to 74% with AAP10 (% values: n% of epicardial action potentials showed a duration which scattered around the mean value in the range of ⁇ 5 ms, which corresponds to a decrease in the dispersion).
- the new peptide is thus not only more potent, but also more effective than AAPIO with regard to the maximum effect and therefore represents an advance over AAPIO.
- lidocaine belongs to those with a recognized relatively low proarrhythmic risk, while flecainide is generally considered to have a very high proarrhythmic risk.
