The global modification of mammalian and plasmid DNAs by novel platinum compounds, trans-[PtCl(2)(NH(3))(Am)], where Am=2 -methylbutylamine or sec-butylamine was investigated in cell-free media using various biochemical and biophysical methods. These modifications were analyzed in the context of the
Repolarizing Tumor-associated macrophages (TAMs) to anti-tumor M1 macrophages with microRNA (miR) is a plausible approach for cancer treatment. However, how to achieve TAM-targeted miR delivery remains a challenge. The present study generated redox/pH dual-responsive hybrid polypeptide nanovectors,
Eukaryotic translation initiation factor 5A (eIF-5A) is the only cell protein that contains the unusual basic amino acid hypusine [N epsilon-(4-amino-2-hydroxybutyl)lysine]. Hypusine is formed by the transfer of the butylamine portion from spermidine to the epsilon-amino group of a specific lysine
In Thailand, smoking of commercial cigarettes and of handmade cigarettes has drastically increased in recent decades. Cancer of the lung and of the upper aero-digestive tract have also increased in Thailand as they have in many other countries. It is our working hypothesis that the increase of
Activity of caspases 3, 9, 6 has been investigated in erythroleukemia K562 cells under conditions of induction or inhibition of erythroid differentiation using cyclophosphane (N'-bis-(beta-chlorethyl)-N'-O-trimethyl ester of diamide of phosphoric acid, antitumour agent of oncologic practice) and two
A series of complexes of the general formula trans-[PtCl2(Am)(pip-pip)] x HCl where pip-pip is 4-piperidinopiperidine and Am is NH3, methylamine (MA), dimethylamine (DMA), n-propylamine (NPA), isopropylamine (IPA), n-butylamine (NBA), or cyclohexylamine (CHA) were prepared and characterized, and
Sigma receptors are small membrane proteins implicated in a number of pathophysiological conditions, including drug addiction, psychosis, and cancer; thus, small molecule inhibitors of sigma receptors have been proposed as potential pharmacotherapeutics for these diseases. We previously discovered
The photocytotoxicity of a series of anticancer trans-dihydroxido [Pt(N(3))(2)(OH)(2)(NH(3))(X)] (X = alkyl or aryl amine) platinum(IV) diazido complexes has been examined, and the influence of cis-trans isomerism has been investigated. A series of photoactivatable Pt(IV)-azido complexes has been
The synthesis of dihydro furonaphth[1,3]oxazine derivatives 3 was performed through a Mannich-type condensation between 2-cyano-5-hydroxy-3-methylnaphtho[1,2]furan 2a, 1.5 eq of a primary amine and 3 eq of formaldehyde. Similarly, 2-cyano-5-hydroxy-3-methylfuro[2,3-f]quinoline 2b gave the dihydro
The adsorption of the proteins CD13, mucin and bovine serum albumin on VLGXE-Au and YNGRT-Au interfaces was monitored by electrochemical impedance spectroscopy in the presence of [Fe(CN)6](3-/4-). The hydrophobicity of the Au surface was tailored using specific peptides, blocking agents and
