The invention provides methods for treating cancers, such as melanoma and/or metastatic melanoma, using compounds that interact with and/or inhibit cellular proteins lamin A/C, ATP-dependent RNA helicase DDXl (DDXl), heterogeneous nuclear ribonuclear protein H1/H2 (hnRNP H2), and/or heterogeneous nuclear ribonuclear protein A2/B1 (hnRNP A2/B 1). The invention additionally provides a method for identifying compounds active against melanoma cells.

the HyCoSuL approach, we designed and synthesized novel and selective fluorogenic substrates for each of these three constitutive 20S proteasome activities and applied them to assess inhibition of proteasome subunits by MG-132 and a clinically used inhibitor bortezomib. Our results confirm the utility of designed substrates in biochemical assays. Furthermore, selective peptide sequences obtained in this

Polyamines are a rapidly developing area of vital importance to biomedical science. Selective N-alkylation followed by N-terminal acylation and the complete reduction of carbonyl amide bonds enables the preparation by parallel solid phase synthesis of a wide range of N1,N5,1,4-tetrasubstituted-1,5-diamino-3-azapentane derivatives.

A method for the synthesis of a cyclic ornithine-proline-D-cyclohexylalanine-tryptophan- arginine pentapeptide of Formula A; wherein R1 and R2 are, independently, -H, or -C(O)R3 where R3 is -Ch2Ph, - CH2CH2Ph, -CH=CHPh, -C(NHAC)CH2Ph; the method comprising the steps of; forming a linear proline-D-cyclohexylalanine-tryptophan-arginine-ornithine pentapeptide of Formula B, attached to a polymeric resin; wherein R1 is as for Formula A, RES indicates the polymeric resin, and P1 and P2 are protecting groups; cyclising the linear pentapeptide of Formula B to form a cyclic pentapeptide of Formula C, attached to the polymeric resin; cleaving the cyclic peptide of Formula C from the resin providing a cleaved cyclic pentapeptide having a free amine group of an ornithine residue; optionally substituting the free amine group of the ornithine residue of the cleaved cyclic peptide; removing the protecting groups P1 and P2, to provide the cyclic peptide of Formula A.
of the Phe6 residue by cyclohexyl-Ala (Cha) led to an analogue, [Cha6]U-II(4-11), that was devoid of agonistic activity but was able to dose-dependently suppress the vasoconstrictor effect of U-II on rat aortic rings. These new pharmacological data, by providing further information regarding the structure-activityrelationships of U-II analogues, should prove useful for the rational design of potent
