Abstract
The design and synthesis of 2,6-diphenylthiazolo[3,2-b][1,2,4]triazoles characterized by a large aromatic building block bearing cationic side chains are reported. These molecules are evaluated as telomeric G-quadruplex stabilizers and for their selectivity towards duplex DNA by competition experiments. Two compounds (14a, 19) were found active with high selectivity for telomeric G-quadruplex over duplex DNA.

Abstract
FTase inhibitors constitute a new class of potential cancer therapeutics, especially in colorectal cancer where K-ras-selective mutations exist and have a role in tumorigenesis. The synthesis and biological evaluation of two nonpeptidic molecules (13 and 16) designed on the basis of a zinc chelator imidazole linked to two aromatic fragments able to fit in the "exit groove" and in the "A2 binding site" of FTase are described. These molecules are characterized respectively by a flexible phenylmethyl chain and a more constrained scaffold so as to evaluate their respective influences on site recognition. They have been evaluated in vitro and in vivo against human colon cancer cell lines and 13 not only inhibited tumor growth but also showed no toxic effects at the dose used.

Abstract
Oncogenic Ras proteins whose activation is farnesylation by farnesyltransferase have been seen as important targets for novel anticancer drugs. Inhibitors of this enzyme have already been developed as potential anti-cancer drugs, particularly by rational design based on the structure of the CA(1)A(2)X carboxyl terminus of Ras. Synthesis of a peptidomimetics library via solid-phase synthesis using the Multipin method is described here. The most active hits on cellular assays were resynthesized and enzymatic activity was measured. Compounds A1, A5 and A7 present significant activity on the isolated enzyme (IC(50)=117, 57.3 and 28.5 nM) and their molecular docking in the active site of the enzyme provides details on key interactions with the protein.

Abstract
An expeditious route to the two major metabolites of Zolpidem-and readily applicable to the synthesis of the drug-was established via a cyclization reaction between a 2-aminopyridine and a suitable alpha-bromoacetophenone. The structures of the target compounds were confirmed from a 2D (1)H-(15)N NMR correlation. Their mass spectra contribute to a reliable toxicological identification of the drug in the case of drug-facilitated crimes.

Abstract
The arachidonic acid metabolizing enzymes cyclooxygenase-2 (COX-2) and lipoxygenases (LOXs) have been found to be implicated in a variety of cancers, including prostate cancer. To develop new therapeutic treatments, it therefore seemed interesting to design dual COX-2/5-LOX inhibitors. We report here the synthesis and in vitro pharmacological properties of diarylpyrazole derivatives that have in their structure key pharmacophoric elements to obtain optimal interaction with subsites of active pockets in both enzyme systems. Using a molecular modeling approach, a set of SAR data is proposed, highlighting the importance of the sulfonyl group of one of the aryl moieties in terms of proliferation inhibition and/or apoptosis induction.

Abstract
We recently described a novel series of CA(1)A(2)X peptidomimetics as farnesyl transferase inhibitors (FTIs). These compounds possess an N-(4-piperidinyl)benzamide scaffold mimicking A(1)A(2) residue. Extensive exploration of structure--activity relationships revealed that replacement of cysteine by substituted benzylimidazoles provided nanomolar FTIs with in vitro activities (18e, IC(50) = 4.60 nM on isolated enzyme, EC(50) = 20.0 nM for growth inhibition on a tumor cell line). The molecular docking of 18e and 19e in the active site of the enzyme provided details of key interactions with the protein and showed that the methionine or phenylalanine residue fits into the aryl binding site.

Abstract
The tetrahydroindeno[1,2-b]pyrido[4,3,2-de]quinoline chromophore was initially designed as a DNA intercalating unit because of its planar structure. Unexpectedly, one molecule (15d) bearing two N-methylpiperazine chains on both sides of this condensed pentacyclic skeleton fits into the minor groove of DNA and preferentially recognizes AT-rich sequences. The monosubstituted compound 16d was identified as a potent cytotoxic DNA intercalator, whereas the disubstituted analogue 15d represents a new structural motif for the development of DNA sequence-reading small molecules.

Abstract
Camptothecin consists of a lactone E-ring adjacent to a tetracyclic A-D ring planar chromophore which are essential for topoisomerase I inhibition and DNA interaction, respectively. The A-D ring system can be exploited to develop DNA-binding molecules. Indolizino[1,2-b]quinoline derivatives substituted with a piperidinoethyloxy side chain on the A-ring and an aminomethyl function on the D one were synthesized and their DNA-binding properties and in vitro cytotoxicity investigated.

Abstract
The quinoline chromophore has long formed the basis for the clinical development of novel antitumour agents. Camptothecin derivatives have already proved their clinical efficacy and compounds such as ascididemin (pyridoacridine family), DHDMC (protoberberine family) have a very promising future. During our search for new cytotoxic molecules, we have designed compounds based on the benzo[c]pyrido[2,3,4-kl]acridine skeleton which combines the structural features of ascididemin and DHDMC. Corresponding compounds were synthesized and evaluated for their cytotoxic activity against human prostatic PC-3 cell lines. Some have shown promising biological activity in inhibiting the growth of cell lines which are resistant to camptothecin.

Potent cytotoxic compounds were discovered but no strict correlation with their DNA binding affinity and effects on topoisomerases were observed. DNA is one but not the unique target of these compounds.

Abstract
Camptothecin consists of a lactone E ring adjacent to tetracyclic A-D rings of a planar chromophore, which are essential for topoisomerase I inhibition and DNA interaction. The A-D rings can be exploited to develop DNA-sequence-reading molecules. Indolizino[1,2-b]quinoline derivatives substituted with a piperidinoethyloxy side chain and an aminomethyl function on rings A and D, respectively, were synthesized, and their DNA binding and formaldehyde-mediated bonding properties were investigated.

Abstract
A new series of nonpeptide AT(1) receptor antagonists were recently developed, based on the structure of irbesartan (Le Bourdonnec et al. J. Med. Chem. 2000, 43, 2685-2697). The lead compound 1 displayed high selectivity for the AT(1) receptor subtype but lower binding affinity than irbesartan. As expected from molecular modeling studies, extension of the pyrazolidine-3,5-dione scaffold to the six-membered heterocycle tetrahydropyridazine-3,6-dione led to an enhancement of the binding affinity toward the AT(1) receptor.

Abstract
The synthesis of an array of 5-phenyloxazole derivatives bearing a variety of hydroxyalkyl groups at the C-2 position of the heterocyclic nucleus and possessing a formyl or a carboxyl function at C-4 is reported. These bifunctionalized compounds have been efficiently prepared by addition of carbonylated electrophiles to the 2-lithio derivative of 5-phenyloxazole preliminarily equipped with an oxazoline unit at the 4-position of the oxazole nucleus. It is demonstrated that this protocol offers a double advantage since it suppresses the troublesome electrocyclic ring-opening reaction and allows access to the target compounds by simple chemical transformation of the oxazoline ring system.

Abstract
A series of molecules of therapeutic interest, possessing the new skeleton of 1H-benzo[c]pyrido[2,3,4-kl]acridine with acyl or aminoacyl and methoxy or aminoalkoxy substituents on the aromatic homocycles were synthesized by means of a Friedländer-type reaction. The requisite 5-aminodihydroquinoline-4-ones 1, whose preparation is described, were reacted with the appropriate alpha-tetralones 2 using an acidic catalyst (PPTS) under azeotropic conditions. Optimized reaction time and yield depend on temperature, which must not be below 90 degrees C.

Abstract
New CA(1)A(2)X peptidomimetics are described as Ras farnesyl transferase inhibitors (FTIs). They include cysteine and methionine as mimetics of the C-terminus sequence of farnesylated proteins. Furthermore, cysteine was replaced by heterocycles, taking into account the role of zinc and the metabolic instability of amino acids. The molecular docking of 8 in the active site of the enzyme and the pharmacological evaluation of the compounds are illustrative of a new class of FTIs.

Abstract
The development of small-molecule antagonists of the substance-P-preferring tachykinin NK1 receptor offers an excellent opportunity to exploit these molecules as novel therapeutic agents in diverse pathologies such as depression, emesis or asthma. GR71251 has previously been identified as a potent and selective substance-P-receptor antagonist. We have therefore undertaken the synthesis of new pseudopeptidic analogues based on the C-terminal sequence of GR71251. The evaluation of binding affinities toward NK1 and NK2 receptors has enabled us to propose new selective NK1 ligands with high affinity. Structure-activity relationships showed that the Trp-OBzl(CF3)2 moiety is essential for NK1 affinity and that the introduction of building units such as spirolactam, lactam or proline, leading to a constrained peptide, increased selectivity for NK1 receptors. These compounds constitute a useful starting point for new substance P antagonists and represent an attractive lead series for further studies on the design of specific NK1 antagonists.

Abstract
Chemical modifications of dual NK1/NK2 ligand Cbz-Gly-Leu-Trp-OBzl(CF3)2 (1) enabled us to create a high NK1 selective ligand Cbz-Pro-Leu-Trp-OBzl(CF3)2 (2). A determination of the conformational behavior of tripeptide 2 in solution is described. The 1D and 2D 1H-NMR techniques (COSY and ROESY) were used to assign resonances. Observed interproton distance restraints were considered to characterize conformational behavior. Spectral data indicate that tripeptide 2 presents a rigidified structure in DMSO stabilized by H-bond in two gamma-turns. Agreement with experimental data was obtained by averaging the 1H-NMR parameters over several combinations of low-energy conformations.

Abstract
The brominated anilinoquinazoline derivative PD153035 exhibits a very high affinity and selectivity for the epidermal growth factor receptor tyrosine kinase (EGF-R TK) and shows a remarkable cytotoxicity against several types of tumor cell lines. In contrast, its N-methyl derivative, designated EBE-A22, has no effect on EGF-R TK but maintains a high cytotoxic profile. The present study was performed to explore the possibility that PD153035 and its N-methyl analogue might interact with double-stranded DNA, which is a primary target for many conventional antitumor agents. We studied the strength and mode of binding to DNA of PD153035 and EBE-A22 by means of absorption, fluorescence, and circular and linear dichroism as well as by a relaxation assay using human DNA topoisomerases. The results of various optical and gel electrophoresis techniques converge to show that both drugs bind to DNA and behave as typical intercalating agents. In particular, EBE-A22 unwinds supercoiled plasmid, stabilizes duplex DNA against heat denaturation, and produces negative CD and ELD signals, as expected for an intercalating agent. Extensive DNase I footprinting experiments performed with a large range of DNA substrates show that EBE-A22, but not PD153035, interacts preferentially with GC-rich sequences and discriminates against homooligomeric runs of A and T which are often cut more readily by the enzyme in the presence of the drug compared to the control. Altogether, the results provide the first experimental evidence that DNA is a target of anilinoquinazoline derivatives and suggest that this N-methylated ring system is a valid candidate for the development of DNA-targeted cytotoxic compounds. The possible relevance of selective DNA binding to activity is considered. The unexpected GC-selective binding properties of EBE-A22 entreat further exploration into the use of N-methylanilinoquinazoline derivatives as tools for designing sequence-specific DNA binding ligands.

Abstract
On the basis of the structure of the non-peptide receptor antagonist irbesartan, a new series of AT(1) ligands was designed. In these compounds the central imidazolone nucleus of irbesartan was replaced by a pyrazolidine-3,5-dione structure. The key intermediate N-alkylpyrazolidine-3,5-diones were synthesized according to a new and general method. The most active compounds possess a spirocyclopentane ring at position 4, a linear butyl chain at position 1, and the [2'-(5-tetrazolyl)biphenyl-4-yl]methyl or [2'-(benzoylaminosulfonyl)biphenyl-4-yl]methyl group at position 2. Affinity toward the AT(1) and AT(2) receptors was assessed by the ability of the compounds to competitively displace [(3)H]AII from its specific binding sites. The most active compounds, 28 and 48, displayed high affinity for the AT(1) receptor, good selectivity AT(1) versus AT(2), and potent in vitro antagonist activity.

Abstract
The mitogenic action of EGF is mediated by ligand-induced autophosphorylation of the EGF receptor (EGF-R), which is commonly overexpressed in numerous human cancers. Inhibitors of receptor tyrosine kinase (RTK) activity could therefore be considered as effective potential antitumor agents. For this purpose, 4-aminoquinazoline derivatives were prepared and evaluated for their ability to inhibit RTK activity and the autophosphorylation of EGF-R. In addition, these compounds were tested on A431 cell growth to estimate their antiproliferative effect. The results showed that the substituent at the 4-position of the quinazoline ring must be an aromatic amine carrying small lipophilic electron-withdrawing groups on the 3- (or 2-) position of the phenyl ring. This aromatic moiety might be far from the quinazoline provided that the linking group is conformationally restricted, such as with piperazine. Hydrophilic and non-aromatic substituents such as morpholine gave completely inactive compounds. Introduction of a bulk at the 2-position of the quinazoline ring in 2,4-diaminoquinazolines or tricyclic compounds led to inactive products. This study reports additional structure-activity relationships of a well-characterized series to develop new inhibitors of EGF-R-associated tyrosine kinase activity.
