R-M-162	Cyclo(-Leu-Trp),CAS：15136-34-2	The diketopiperazine cyclo(Leu-Trp) has been isolated by Minamiura et al. from casein hydrolyzate by bacterial proteinase. It is one of the bitter compounds detected in cheese. Cyclo(L-Leu-L-Trp) is a diketopiperazine metabolite originally isolated from Penicillium. It is active against various bacteria (MICs = 125-1000 µg/ml) and fungi (MICs = 8-64 µg/ml), and it inhibits the production rate of hydroxy radicals in an electron spin resonance (ESR) spectroscopy-based assay (IC50 = 1.8 µM). Cyclo(L-Leu-L-Trp) is a bitter tastant that can rapidly permeate rat taste cell membranes ex vivo when used at a concentration of 1 mM. It also acts as a melatonin receptor agonist in X. laevis melanophores, inhibiting cAMP accumulation when used at a concentration of 20 µM, an effect that is blocked by the melatonin receptor antagonist luzindole (Cay-15998).	price>
R-M-203	Autocamtide-2 Peptide	Autocamtide-2 is a highly selective peptide substrate for calcium/calmodulin-dependent protein kinase II (CaMKII), which belongs to the CAMK Ser/Thr protein kinase family. The sequence derives from the Thr-286 autophosphorylation site of the alpha subunit of CaMKII. Autocamtide-2 contains the R-X-X-S/T consensus site surrounded by basic residues for improved binding to phosphocellulose. CaMKII is a prominent kinase in the central nervous system that functions in long-term potentiation and neurotransmitter release. Autophosphorylation of Thr-286 allows the kinase to switch from a calmodulin-dependent to a calmodulin-independent state. CaMKII phosphorylates Autocamtide-2 with a Km of 2 uM whereas protein kinase C (PKC) has a Km > 50 uM and protein kinase A (PKA) has no activity.	price>
