Objective: Cancer has risen as the main cause of diseases with the highest rate of mortality in the world. Drugs used in cancer, usually demonstrate side effects on normal tissues. On the other hand, anticancer small peptides, effective on target tissues, should be safe on healthy organs, as being naturally originated compounds. In addition, they may have good pharmacokinetic properties. carnos...

introduction: over expression of selected peptide receptors in human tumors has been shown to represent clinically relevant targets for cancer diagnosis and therapy. the aim of this work was to investigate neuropeptide y (npy) as a new radiopharmaceutical for diagnosis of breast cancer. methods: a neuropeptide y analogues with y1 receptor preference and agonistic properties was synthesized by s...

In this work, linear and cyclic disulfide heptapeptides of Longicalycinin A have been successfully synthesized by solid phase methodology with Fmoc /t-Bu and solution phase, respectively. 2-Chlorotrityl chloride resin (2-CTC) was used as a solid support. The synthesized linear disulfide analogue of Longicalycinin A was cleaved from the resin as a protected peptide. The final deprotection was pe...

We present a streamlined approach to sidechain acyl hydrazides of aspartic and glutamic acids – user friendly precursors peptide macrocycles glycopeptide analogues.

b ackground: brevinin-2r, as 25 amino acids peptide of the skin of r ana ridibunda frog, possesses potent antimicrobial and low hemolytic activity. it has an n-terminal hydrophilic region and a c-terminal loop that is delineated by an intra-disulfide bridge. in our study, brevinin-2r and its diastereomer as well  as its  cyclic  analogue  were  synthesized  and  characterized  in  order  to inv...

The effect of introducing D-amino acid residues in an hexapeptide was examined both at the antigenic and immunogenic levels. A series of D-analogues of the model peptide of sequence IRGERA corresponding to the COOH-terminal residues 130-135 of histone H3 were produced. Four analogues contained a single change of an L-residue by the corresponding enantiomer, one peptide contained two D-residues ...

Melanocortin-1 (MC1) receptor is an attractive melanoma-specific target over-expressed on the surface of melanoma cells. Alpha-melanocyte stimulating hormone (alpha-MSH) peptide analogues can specifically bind MC1 receptors with nanomolar binding affinities, making alpha-MSH peptide analogues very promising candidates for developing effective melanoma-specific imaging probes. This review highli...
