OBJECTIVES The aim of this study was to evaluate miltefosine and four synthetic compounds (TCAN26, TC19, TC106 and TC117) for their in vitro inhibitory activity against Candida albicans planktonic and biofilm cells and investigate whether these compounds are able to inhibit the biofilm formation and to reduce the viability of mature C. albicans biofilm(More)
BACKGROUND The search for novel chemical entities targeting essential and parasite-specific pathways is considered a priority for neglected diseases such as trypanosomiasis and leishmaniasis. The thiol-dependent redox metabolism of trypanosomatids relies on bis-glutathionylspermidine [trypanothione, T(SH)2], a low molecular mass cosubstrate absent in the(More)
Sodium potassium pump (Na(+)/K(+)ATPase) is a validated pharmacological target for the treatment of congestive heart failure. Recent data with inotropic drugs such as digoxin & digitoxin (digitalis) suggest a potent anti-cancer action of these drugs and promote Na(+)/K(+)ATPase as a novel therapeutic target in cancer. However, digitalis have narrow(More)
A series of new 2-[3-(2-alkyloxy-ethyl)-adamantan-1-yl]-ethoxy substituted ether phospholipids was synthesized and their antileishmanial activity was evaluated against Leishmania infantum amastigotes. The majority of the new analogues were significantly less cytotoxic than miltefosine while, antiparasitic activity depended on the length of the 2-alkyloxy(More)
Sodium potassium pump (Na+/K+ ATPase) is a validated pharmacological target for the treatment of various cardiac conditions. Recent published data with Na+/K+ ATPase inhibitors suggest a potent anti-cancer action of these agents in multiple indications. In the present study, we focus on istaroxime, a Na+/K+ ATPase inhibitor that has shown favorable safety(More)
An efficient three-step solid-phase synthesis of diverse 3,5-disubstituted-2-aminofuranones has been developed. alpha-Hydroxy acids loaded on a nitrophenyl carbonate derivative of Wang resin are used as acylating agents for the C-acylation of active methylene compounds and the resulting intermediates provided, through a cyclative cleavage reaction, the(More)
A series of N-substituted-quinolinone-3-aminoamides and their hybrids containing the alpha-lipoic acid functionality were designed and synthesized as potential bifunctional agents combining antioxidant and anti-inflammatory activity. The new compounds were evaluated for their antioxidant activity and for their ability to inhibit in vitro lipoxygenase as(More)
The synthesis and characterization of two new tetronic acid zinc (II) complexes of the empirical formulae [Zn(L-H)(2)(H(2)O)(2)] (1) and [Zn(L-H)(2)(H(2)O)(MeOH)]H(2)O (2) found within the same crystal are reported. The zinc ions bind through alkoxide and carbonyl groups of the ligand 3-methoxycarbonyl-5-phenyl tetronic acid (LH) as indicated by (1)H NMR(More)
The catalytic activity of FeCl3 for the synthesis of a variety of 4-substituted coumarins using high energy techniques has been investigated. The ultrasonic-assisted conditions provide a useful complement to the Pechmann reaction, affording the coumarin derivatives in excellent yields, under solvent-free conditions, in short reaction times using an(More)
Neurotrophin receptors mediate a plethora of signals affecting neuronal survival. The p75 pan-neurotrophin receptor controls neuronal cell fate after its selective activation by immature and mature isoforms of all neurotrophins. It also exerts pleiotropic effects interacting with a variety of ligands in different neuronal or non-neuronal cells. In the(More)
