Aqueous aza-michael reaction of conjugated alkenes: Toward spermine
Joshi, Jigar H.,Saiyed, Akeel S.,Bedekar, Ashutosh V.
, p. 2857 - 2863 (2010)
An aqueous aza-Michael reaction is efficiently achieved with excellent conversions without any additives. The method works very well on a molar scale with selectively for aliphatic amines. An intermediate for spermine is also made by this green process.
Discovery of novel alkylated (bis)urea and (bis)thiourea polyamine analogues with potent antimalarial activities
Verlinden, Bianca K.,Niemand, Jandeli,Snyman, Janette,Sharma, Shiv K.,Beattie, Ross J.,Woster, Patrick M.,Birkholtz, Lyn-Marie
, p. 6624 - 6633 (2011)
A series of alkylated (bis)urea and (bis)thiourea polyamine analogues were synthesized and screened for antimalarial activity against chloroquine-sensitive and -resistant strains of Plasmodium falciparum in vitro. All analogues showed growth inhibitory ac

The P2 transporter is a nucleoside transporter which is unique to the protozoan parasite Trypanosoma brucei, the causative organism of Human African Trypanosomasis. The transporter has been shown to bind some structural motifs not recognized by other tran

Ianthelliformisamines 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 of their analogues (39 analogues) has been synthesized by employing 3-phenylacrylic acid derivatives and Boc-protected polyamine chains through various combinations of these two fragments differing in phenyl ring substitution, double bond geometry or chain length of the central spacer of the polyamine chain (shown in red color). All the synthesized compounds (ianthelliformisamines A-C and their analogues) were screened for antibacterial activity against both Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) strains. All synthetic analogues of ianthelliformisamine A showed bacterial growth inhibition against both strains (Escherichia coli and Staphylococcus aureus), having MIC values in the range of 117.8-0.10 μM, while none of the synthetic analogues of ianthelliformisamine C as well as the parent compound showed any detectable antibacterial activity. Interestingly, some of the synthetic analogues of ianthelliformisamines A and B exerted a bactericidal effect against both E. coli and S. aureus strains, decreasing viable bacterial count by 99% at concentrations as low as 2 × MIC.

Polyamine functionalized carbon nanotubes: Synthesis, characterization, cytotoxicity and siRNA binding
Singh, Prabhpreet,Samori, Cristian,Toma, Francesca Maria,Bussy, Cyrill,Nunes, Antonio,Al-Jamal, Khuloud T.,Menard-Moyon, Cecilia,Prato, Maurizio,Kostarelos, Kostas,Bianco, Alberto
supporting information; experimental part, p. 4850 - 4860 (2011/10/09)
In this work we have synthesized a new series of cationic carbon nanotubes (CNTs) for siRNA binding. Both single- and multi-walled CNTs have been modified by addition or amidation reaction with short linear polyamine chains including putrescine, spermidin
(Bis)urea and (Bis)thiourea inhibitors of lysine-specific demethylase 1 as epigenetic modulators
Sharma, Shiv K.,Wu, Yu,Steinbergs, Nora,Crowley, Michael L.,Hanson, Allison S.,Casero, Robert A.,Woster, Patrick M.
scheme or table, p. 5197 - 5212 (2010/09/09)
The recently discovered enzyme lysine-specific demethylase 1 (LSD1) plays an important role in the epigenetic control of gene expression, and aberrant gene silencing secondary to LSD1 overexpression is thought to contribute to the development of cancer. W

Solid-phase synthesis of diamine and polyamine amino acid derivatives as HIV-1 Tat-TAR binding inhibitors
Bueno, G. Jimenez,Klimkait,Gilbert,Simons
, p. 87 - 94 (2007/10/03)
A series of diamine and polyamine derivatives, either free amines or salts (HCl or TFA), of aspartic and glutamic acid were prepared in excellent yields using Rink Amide solid-phase synthesis. The asparagine and glutamine derivatives were all evaluated for their ability to inhibit Tat-TAR binding using a FIGS cellular assay, with the polyamine derivatives exhibiting the most promising binding activity.
Sinulamide: An H,K-ATPase inhibitor from a soft coral Sinularia sp.
Sata, Noriko U.,Sugano, Michihiro,Matsunaga, Shigeki,Fusetani, Nobuhiro
, p. 719 - 722 (2007/10/03)
Sinulamide (1), a new tetraprenylated spermine derivative, has been isolated from a soft coral Sinularia sp. as an H,K-ATPase inhibitor. The structure was assigned on the basis of spectroscopic data and confirmed by a total synthesis.
