Selected homologs, analogs, and acylated derivatives of spermine and spermidine, together with several heterocyclic and aromatic compounds containing a novoldiamine side chain, were prepared and evaluated biologically. Several compounds possessed activity against B-16 melanoma and human epidermoid carcinoma of the nasopharynx.

A series of alkylated (bis)urea and (bis)thiourea polyamineanalogues were synthesized and screened for antimalarial activity against chloroquine-sensitive and -resistant strains of Plasmodium falciparum in vitro. All analogues showed growth inhibitory activity against P. falciparum at less than 3 μM, with the majority having effective IC50 values in the 100–650 nM range. Analogues arrested parasitic

one pot. A similar process gave H2N(CH2)3NBoc(CH2)3NBoc(CH2)3NH2. BocMeN(CH2)3NHMe was alkylated by 1,3-dibromopropane to give BocMeN(CH2)3NMe(CH2)3NMe(CH2)3NMeBoc. A cyanoethylation/reduction sequence extended H2N(CH2)3NBoc(CH2)3NBoc(CH2)3NH2 to give H2N(CH2)3NBoc(CH2)3NBoc(CH2)3NBoc(CH2)3NBoc(CH2) 3NH2, which was converted to its mono- and di-MeOPEG550 derivatives. Deprotection gave the linear polyamine

The effect of the temperature on the corrosion behavior with the addition of different concentrations of new diamine compounds (3-[2-(2-cyano-ethylamino)-methylamino]-propionitrile ( P1 ); 3-[2-(2-cyano-ethylamino)-ethylamino]-propionitrile ( P2 ), and 3-[6-(2-cyano-ethyla

A–C are a novel class of bromotyrosine-derived antibacterial agents isolated recently from the marine sponge Suberea ianthelliformis. We have synthesized ianthelliformisamines A–C straightforwardly by the condensation of (E)-3-(3,5-dibromo-4-methoxyphenyl)acrylic acid and the corresponding Boc-protected polyamine followed by Boc-deprotection with TFA. Further, using this reaction protocol, a library
