Cyclo(his-pro) TFA, an orally active cyclic dipeptide structurally related to tyreotropin-releasing hormone, has shown inhibitory effects on NF-κB nuclear accumulation. Additionally, it possesses the ability to cross the blood-brain barrier and impact various inflammatory and stress responses [1, 2].
Cyclo(Tyr-Pro) shows antibacterial activity towards several marine bacterial species, it also shows weak antagonistic activity against VEGFR2 -CD. Cyclo(Tyr-Pro) and cyclo(Pro-Val) are toxic to both suspension cells and seedlings of Pinus thunbergii, whic
Cyclo(Pro-Pro) tasted bitter.Verpacamides A-D, a sequence of C11N5 diketopiperazines relating cyclo(Pro-Pro) to cyclo(Pro-Arg), from the marine sponge Axinella vaceleti is possible biogenetic precursors of pyrrole-2-aminoimidazole alkaloids.
Cyclo(L-Ala-L-Pro) and cyclo(L-Val-L-Pro) inhibit aflatoxin production of Aspergillus parasiticus and Aspergillus flavus in liquid medium at concentrations of several hundred uM without affecting fungal growth.
Cyclo(Gly-(L)-Pro) shows immunostimulatory properties. Cyclo(Gly-l-Pro) exhibits potent inhibition of TNF-α release with the IC50 values of 4.5 ug/mL, respectively, it also exhibits significant diminution of IL-1β and IL-6 mRNA-expression levels and NO pr
Cyclo(Pro-Gly) is an active metabolite of piracetam-N-phenylacetyl-L-prolylglycine (GWS-111), it shows a greater resistance to an enzymatic effect than natural neuropeptides. Cyclo-(Gly-Pro) shows cytotoxicity at the concentration of 10 umol L, it inhibit
