cyclo(pro-val)

Cyclo(Pro-Val) (Cyclo(prolylvalyl)) is obtained from the marine fungus and shows moderate antifungal and weak antitumor activities. Cyclo(Pro-Val) inhibits the growth of Bacillus subtilis with MIC of 0.8 g/L.

Cyclo(Pro-Val)-d4 is the deuterium-labeled version of Cyclo(Pro-Val), which can be isolated from Pseudomonas fluorescens GcM5-1A and exhibits cytotoxic properties.

Cyclo(L-Pro-L-Val), a 2,5-diketopiperazine extracted from the fruits of Mycobacterium chiliolyticum AZ2 and Mycobacterium leprae, possesses anti-inflammatory activity and virulence activity against phytopathogenic microorganisms (e.g., R. fascians LMG 3605) and inhibits Gram-positive plant pathogens.Cyclo(L-Pro-L-Val) significantly inhibited IKKα phosphorylation and IκBα and NF-κB activation as well as iNOS and COX-2 activation in a concentration Cyclo(L-Pro-L-Val) significantly inhibited the phosphorylation of IKKα, IKKβ, IκBα, and NF-κB, as well as the activation of iNOS and COX-2 in a concentration-dependent manner, and is a potential therapeutic agent for the treatment of inflammation-related diseases.

Cyclo(D-Pro-L-Val) inhibits the activity of β-glucosidase (β-glycosidase) with an IC50 of 75 μg/mL and exhibits either no inhibitory effects or only weak inhibition on other glycosidases.

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(D-Val-L-Pro) is a natural product for research related to life sciences. The catalog number is TN6670 and the CAS number is 27483-18-7.

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
