Abstract
Two series of N-alkyl, N-alkoxy, and N-hydroxy bisguanidines derived from the N-phenylbenzamide and 1,3-diphenylurea scaffolds were synthesised in three steps from the corresponding 4-amino-N-(4-aminophenyl)benzamide and 1,3-bis(4-aminophenyl)urea, respectively. All of the new compounds were evaluated in vitro against T. b. rhodesiense (STIB900) trypomastigotes and Plasmodium falciparum NF54 parasites (erythrocytic stage). N-alkoxy and N-hydroxy derivatives showed weak micromolar range IC50 values against T. b. rhodesiense and P. falciparum whereas the N-alkyl analogues displayed submicromolar and low nanomolar IC50 values against P. falciparum and Trypanosoma brucei, respectively. Two compounds, 4-(2-ethylguanidino)-N-(4-(2-ethylguanidino)phenyl)benzamide dihydrochloride (7b) and 4-(2-isopropylguanidino)-N-(4-(2-isopropylguanidino)phenyl)benzamide dihydrochloride (7c), which showed favourable drug-like properties and in vivo efficacy (100% cures) in the STIB900 mouse model of acute human African trypanosomiasis represent interesting leads for further in vivo studies. The binding of these compounds to AT-rich DNA was confirmed by surface plasmon resonance (SPR) biosensor experiments.

Abstract
Pyrido[4,3-d]pyrimidin-4(3H)-one (1) was prepared by reacting 2-trifluoromethyl-4-iodo-nicotinic acid (2) with amidine 9a catalyzed by Pd(2)(dba)(3) and Xantphos, followed by cyclization effected with HBTU and subsequent demethylation using PhBCl(2). The amidine arylation method was found applicable for the syntheses of quinazolin-4(3H)-ones. Thus, reaction of 2-bromo or 2-iodo benzoate esters with amdidines afforded substituted quinazolin-4(3H)-ones in 44-89% yields.

Abstract
A small library of heterocycle-fused quinazolin-4-ones was prepared and evaluated as kinase inhibitors. The key step of the two-step process involves the environmental friendly thermolysis of N-ethoxycarbonyl-N'-(hetero) arylguanidines at 130 °C in water. The cyclization is fully regioselective. The most active molecules, 7-(2-hydroxyethylamino)- and 7-(3-hydroxypropylamino)-pyrazolo[4,3-f]quinazolin-9-ones, inhibit DYRK1A and CLK1 at submicromolar concentrations, indicating the potential interest of this new heterocycle in drug design.

Abstract
A concise and highly divergent synthetic route has been developed to rapidly access 1,3,6-trisubstituted pyrazolopyrimidines. The synthesis features a microwave assisted one-pot N1-alkylation/Suzuki-Miyaura reaction as the key step. The sequence of the synthetic scheme can be varied to selectively modify the N1, C3, or C6 position at a late synthetic stage, thereby providing a highly efficient approach to explore the structure-activity relationships of pyrazolopyrimidine derivatives. The scope of these reactions has also been explored.

Abstract
An original route to 2-alkyamino-4-phenylquinazolines in three steps from simple (hetero)aromatic amines is reported here. The key step involves the intramolecular cyclization of benzoyl arylguanidines performed in [OMIm]Cl ionic liquid. The basic (hetero)aromatic guanidines deprotonate the imidazolium-based ionic liquid, thus triggering the cascade process ultimately leading to the intramolecular cyclization. This reaction is the first example of a Friedel-Crafts-type reaction in which an N-heterocyclic carbene is involved in the formation of the electrophilic intermediate.

The key Friedel-Crafts intramolecular cyclization was realized under microwave irradiation using montmorillonite K-10 clay as a catalyst. The pyrimido[4,5-c]carbazole derivative shows significant micromolar IC(50) against cancer cell lines. Unlike similar carbazole and indolocarbazole compounds, the molecule does not interfere with topoisomerase activity.

Abstract
The present article reports on the design and the synthesis of a series of mono- and bis-pyrimidinoacridines and their evaluation as a novel family of quadruplex-binders. It is shown that bispyrimidinoacridines represent an interesting compromise between easy synthetic access and efficiency in terms of quadruplex interaction (both affinic and selective), as judged by G4-FID assay and molecular modelling. The present study also highlights that control of the pi-stacking interactions taking place between the ligand and the accessible G-tetrad of a quadruplex-DNA is indeed essential for good recognition but not exclusively (key role of direct and water-mediated H-bonds). The introduction of additional amino side chains, valuable in the acridine series, results here in steric perturbations of the ligand/quadruplex recognition and lowers the quadruplex/duplex selectivity.
