A set of azapeptides was designed based on the Ala-Val-Pro-Ile peptide (derived from Smac protein) to activate caspase-9 and induce apoptosis in breast cancer cells.
The patients were divided into two groups based on the difference in ALA between the operated hip and the contralateral native hip.
Based on the observation that He-ALA induces a high porphyrin synthesis in brain (Perotti et al, 2002), we had suspected that He-ALA was neurotoxic; however, this cannot be applied to undecanoyl-ALA because this ALA derivative produces negligible amounts of porphyrins in brain (Casas et al, unpublished results).
Both were based on the CCK2R binding peptide sequence Ala-Tyr-Gly-Trp-Met/Nle-Asp-Phe-amide that shows high affinity to the CCK2R [22] 22], but differed in the N-terminal amino acids ('spacer sequence') to investigate the influence of different spacer variants on affinity, specificity and pharmacokinetic properties of the peptides.
The inhibitors were designed based on the potent tripeptidic Z-Val-Leu-Ala(pyrrolidone-3-yl -2-benzothiazole pyrrolidone-3-yl -2-benzothiazole valine unit was substituted with a variety of distinct moieties.
Novokinin (Arg-Pro-Leu-Lys-Pro-Trp) is a potent hypotensive peptide previously designed based on the structure of ovokinin(2 7) (Arg-Ala-Asp-His-Pro-Phe), a vasorelaxing and hypotensive peptide derived from ovalbumin.
The level of ALA achieved was based on the fat composition of usual infant vegetable formula.
Fluorescence-guided resection is based on the use of 5-aminolevulinic acid (5-ALA), an endogenous intermediate of the porphyrin biosynthesis pathway.
They include synthetic linear peptides, synthetic cyclic peptides, and non-peptidyl peptidomimetics designed based on the cell adhesion recognition (CAR) sequence His-Ala-Val.
Previous studies have suggested that 5-aminolevulinic acid (ALA) may be used topically on the cervix to allow optical detection of cervical dysplasia, based on the fluorescence of protoporphyrin IX (PpIX) synthesized in situ from ALA.
Alas, we did not, based on the wave of correct answers we received this week.
