Structure−Activity Relationships of a Novel Series of Urotensin II Analogues: Identification of a Urotensin II Antagonist
of the Phe6 residue by cyclohexyl-Ala (Cha) led to an analogue, [Cha6]U-II(4-11), that was devoid of agonistic activity but was able to dose-dependently suppress the vasoconstrictor effect of U-II on rat aortic rings. These new pharmacological data, by providing further information regarding the structure-activityrelationships of U-II analogues, should prove useful for the rational design of potent

toxicity. Peptide 3 exhibited excellent cell viability of 94.3 % at 2 μM and of 100 % at 4 μM and 10 μM. CD study showed that peptide 3 restrict the conformation transition of Aβ1-42 peptide towards cross-β-sheet structure and electron microscopy validated the absence of Aβ aggregates as indicated by the altered morphology of Aβ1-42 in the presence of peptide 3. The HRMS-ESI, DLS and ANS studies were performed
The present invention relates to novel Mannose-binding lectin (MBL)-associated serine protease (MASP) inhibitory bicyclic compounds, as well as analogues and derivatives thereof, to processes for the preparation thereof, to the use thereof alone or in combinations for treatment and/or prevention of diseases and to the use thereof for production of medicaments for treatment and/or prevention of diseases, especially for treatment and/or prevention of renal and cardiovascular disorders and of ischemia reperfusion injuries.
