Biological evaluation of tetracationic compounds based on two 1,4-diazabicyclo[2.2.2]octane moieties connected by different linkers

A series of 1,4-diazabicyclo[2.2.2]octane derivatives differing by linker moiety was evaluated for activity against several strains of both Gram-positive and Gram-negative bacteria including drug-resistant strains, one strain of fungus and influenza virus A/Puerto Rico/8/34 (H1N1). All compounds exhibited high antibacterial activity against all bacteria except Proteus vulgaris. The minimum inhibitory concentrations (MICs) of compound 1c with an o-phenylenebismethyl linker and compound 1e with a propylene aliphatic linker were found to be low and were comparable or better to the reference drug ciprofloxacin for Pseudomonas aeruginosa and Staphylococcus aureus. Additionally, a time-kill assay was performed to examine the bactericidal kinetics. Compounds 1c and 1e displayed rapid killing effects against St. aureus and Ps. aeruginosa after 2?h. Furthermore, compounds 1a–c with aromatic linkers and compound 1e showed the highest antiviral activity.

Synthesis of 1,2-Bis(1,4,7,10-tetra-azadodecanyl)ethane, a Double-ring Fully Saturated Macrocycle containing 12-Membered Tetra-aza Subunits

The title compound, a fully saturated bimacrocycle (1), has been obtained through a procedure involving the protection of all but one of the amino nitrogen atoms of each tetra-aza ring which are then bridged by an ethylenic segment; (1) behaves as a dinucleating ligand, forming a dicopper(II) complex in which there is a weak ferromagnetic interaction between the metal atoms.

Kinetics of phosphoramide mustard hydrolysis in aqueous solution

Hydrolysis of phosphoramide mustard was investigated using HPLC, 31P NMR, and GC-MS with specific deuterium labels. The hydrolysis of phosphoramide mustard in sodium phosphate buffers was found to follow apparent first-order kinetics. The rate of hydrolysis was temperature and pH dependent, being slower under acidic conditions. The hydrolysis was not catalyzed by hydroxyl ion, and its pH dependence appeared to be the result of a change in the mechanism of hydrolysis at different pH values. At a pH value approximately above the pK(a) of the phosphoramide mustard nitrogen, the major hydrolytic pathway of phosphoramide mustard was via the formation of the aziridinium ion, followed by nucleophilic attack. At pH values below its pK(a), cleavage of the P-N bond predominated. At pH 7.4, the formation of an aziridinium ion was followed by a rapid hydrolysis to yield the monohydroxy and, subsequently, the dihydroxy products. The hydrolysis at this pH was adequately described by consecutive first-order kinetics. Seven species in the hydrolytic mixture have been identified as intact phosphoramide mustard, N-(2-chloroethyl)-N-(2-hydroxyethyl)phosphorodiamidic acid, N,N-bis-(2-hydroxyethyl)phosphorodiamidic acid, phosphoramidic acid, phosphoric acid, N,N-bis-(2-chlorethyl)amine, and N-(2-chloroethyl)-N-(2-hydroxyethyl)amine by GC-MS with the aid of deuterium labels. Phosphoramide mustard was found to be stabilized by chloride ion. The stabilization was linearly related to the chloride ion concentration, and the mechanism was found to be via the formation of phosphoramide mustard from the aziridinium and chloride ions. Phosphoramide mustard was significantly more stable in human plasma and in 5% human serum albumin as compared to aqueous buffers, an observation that may be important in vivo.

Novel antitumor agent family of 1H-benzo[c,d]indol-2-one with flexible basic side chains: Synthesis and biological evaluation

A series of mono-1H-benzo[c,d]indol-2-one with different amine side chains and bis-1H-benzo[c,d]indol-2-one as novel family of DNA intercalators were designed and synthesized, the contributions of aromatic chromophores and amine side chains for DNA binding properties, for example, intercalation and electrostatic binding, respectively, were evaluated.

Synthesis of novel perfluoroalkyl ether derivatives

A series of novel fluoroether-containing monomers has been designed and prepared based on the commercially available perfluoroalkyl ether acid fluoride. Treating acid fluoride with allyl alcohol, 2-hydroxyethyl methacrylate or N-allylmethylamine allowed for the direct formation of corresponding vinyl-containing fluorinated monomers. High yields of the fluorinated epoxy monomers could be obtained from acid chloride with glycidol; meanwhile, fluorinated diol was prepared from diethanolamine or 3-amino-1,2-propanediol. Moreover, fluorinated monoamine, fluorinated monoalcohol and fluorinated dichloride were also obtained. Most of these fluorinated monomers were liquid at room temperature and exhibited good solubility in common organic solvents.

Synthesis, cytotoxicity, topoisomerase I inhibition and molecular docking of novel phosphoramide mustard sophoridinic acid analogues

A series of novel phosphoramide mustard sophoridinic acid analogues, consisting of nitrogen mustard group and sophoridinic acid scaffold, have been designed, synthesized and evaluated for their topoisomerase inhibitory activity as well as cytotoxicity against six tumor cell lines (SMMC-7721, LoVo, MCF-7, K562, S180 and H22) and a normal cell line (L929). Among the compounds tested, five were found to be potent inhibitors and exhibited potent cytotoxicity against S180 and H22 cell lines with IC50 values of 1–4?μM. Further mechanistic studies showed that this class of compounds acted as novel topoisomerase I (Topo I) catalytic inhibitors by preventing the binding of Topo I to DNA and inhibiting the cleavage of DNA, and molecular docking studies revealed that the binding energy for these compounds was comparable to that for classic Topo I inhibitors CPT and HCPT, indicating that the compounds have an interaction with DNA and Topo I.
