1 This was further confirmed by the use of a cyclic pentapeptide [cyclo(D-Trp,D-Asp,L-Pro, D-Val,L-Leu)] (BQ123), which is selective for ETA receptors. emodepside endothelin receptor type A Homo sapiens
2 This was further confirmed by the use of a cyclic pentapeptide [cyclo(D-Trp,D-Asp,L-Pro, D-Val,L-Leu)] (BQ123), which is selective for ETA receptors. D-Tryptophan endothelin receptor type A Homo sapiens
3 This was further confirmed by the use of a cyclic pentapeptide [cyclo(D-Trp,D-Asp,L-Pro, D-Val,L-Leu)] (BQ123), which is selective for ETA receptors. D-Aspartic acid endothelin receptor type A Homo sapiens
4 This was further confirmed by the use of a cyclic pentapeptide [cyclo(D-Trp,D-Asp,L-Pro, D-Val,L-Leu)] (BQ123), which is selective for ETA receptors. L-Pro endothelin receptor type A Homo sapiens
5 This was further confirmed by the use of a cyclic pentapeptide [cyclo(D-Trp,D-Asp,L-Pro, D-Val,L-Leu)] (BQ123), which is selective for ETA receptors. D-Valine endothelin receptor type A Homo sapiens
6 This was further confirmed by the use of a cyclic pentapeptide [cyclo(D-Trp,D-Asp,L-Pro, D-Val,L-Leu)] (BQ123), which is selective for ETA receptors. Leucine endothelin receptor type A Homo sapiens
7 In the presence of 1 microM BQ123, [125I]ET-1 binding was decreased by 25-30%, whereas [125I]ET-3 binding was unaffected, confirming that 30-35% of ET receptors belong to the ETA subtypes, and that [125I]ET-1 bound to both ETA and ETB receptors with the same high affinity, but [125I]ET-3 bound only to ETB receptors with high affinity. cyclo(Trp-Asp-Pro-Val-Leu) endothelin receptor type A Homo sapiens
