Design and synthesis of potent antitumor water-soluble phenyl N-mustard-benzenealkylamide conjugates via a bioisostere approach

A series of new, water-soluble phenyl N-mustard-benzenealkylamide conjugates containing hydrophilic ω-dialkylaminoalkylamide or ω-cyclic aminoalkylamide moieties were synthesized via a bioisostere approach. These compounds have a broad spectrum of antitumor activity against a panel of human tumor cell lines. Of these derivatives, compound 18b effectively suppressed the growth of colon cancer (HCT-116), prostate cancer (PC3), and lung cancer (H460) xenografts. The growth of HCT-116 xenografts was almost completely suppressed when co-treated with compound 18b and 5-fluorouracil. Furthermore, compound 18b can induce DNA cross-linking and cell-cycle arrest at the G2/M phase. Early preclinical studies, including pharmacokinetics in rats, inhibition of the hERG, and 14 days of acute intravenous injection toxicity, suggest that compound 18b is a promising candidate for further preclinical studies.

Synthesis and characterization of 1H-phenanthro[9,10-d]imidazole derivatives as multifunctional agents for treatment of Alzheimer's disease

Background Alzheimer's disease (AD) is a progressive neurodegenerative brain disorder that is characterized by dementia, cognitive impairment, and memory loss. Diverse factors are related to the development of AD, such as increased level of β-amyloid (Aβ), acetylcholine, metal ion deregulation, hyperphosphorylated tau protein, and oxidative stress. Methods The following methods were used: organic syntheses of 1H-phenanthro[9,10-d] imidazole derivatives, inhibition of self-mediated and metal-induced Aβ1-42 aggregation, inhibition studies for acetylcholinesterase and butyrylcholinesterase, anti-oxidation activity studies, CD, MTT assay, transmission electron microscopy, dot plot assay, gel electrophoresis, Western blot, and molecular docking studies. Results We synthesized and characterized a new type of 1H-phenanthro[9,10-d]imidazole derivatives as multifunctional agents for AD treatment. Our results showed that most of these derivatives exhibited strong Aβ aggregation inhibitory activity. Compound 9g had 74% Aβ1-42 aggregation inhibitory effect at 10 μM concentration with its IC50 value of 6.5 μM for self-induced Aβ1-42 aggregation. This compound also showed good inhibition of metal-mediated (Cu2 + and Fe2 +) and acetylcholinesterase-induced Aβ1-42 aggregation, as indicated by using thioflavin T assay, transmission electron microscopy, gel electrophoresis, and Western blot. Besides, compound 9g exhibited cholinesterase inhibitory activity, with its IC50 values of 0.86 μM and 0.51 μM for acetylcholinesterase and butyrylcholinesterase, respectively. In addition, compound 9g showed good anti-oxidation effect with oxygen radical absorbance capacity (ORAC) value of 2.29. Conclusions Compound 9g was found to be a potent multi-target-directed agent for Alzheimer's disease. General significance Compound 9g could become a lead compound for further development as a multi-target-directed agent for AD treatment.

Design, synthesis and evaluation of 4,5-di-substituted acridone ligands with high G-quadruplex affinity and selectivity, together with low toxicity to normal cells

A series of 4,5-di-substituted acridones have been designed and synthesized. Several compounds show high affinity for telomeric G-quadruplex DNA in classical and competition FRET assays, together with low duplex DNA affinity, although they do not show activity in a telomerase assay or evidence of telomere shortening. They have low toxicity against a panel of cancer cell lines and a normal human fibroblast line, and produce potent senescence-based long-term growth arrest in the MCF7 and A549 cancer cell lines.

Rational design of substituted diarylureas: A scaffold for binding to G-quadruplex motifs

The design and synthesis of a series of urea-based nonpolycyclic aromatic ligands with alkylaminoanilino side chains as telomeric and genomic G-quadruplex DNA interacting agents are described. Their interactions with quadruplexes have been examined by means of fluorescent resonance energy transfer melting, circular dichroism, and surface plasmon resonance-based assays. These validate the design concept for such urea-based ligands and also show that they have significant selectivity over duplex DNA, as well as for particular G-quadruplexes. The ligand-quadruplex complexes were investigated by computational molecular modeling, providing further information on structure-activity relationships. Preliminary biological studies using short-term cell growth inhibition assays show that some of the ligands have cancer cell selectivity, although they appear to have low potency for intracellular telomeric G-quadruplex structures, suggesting that their cellular targets may be other, possibly oncogene-related quadruplexes.

Click chemistry assembly of G-quadruplex ligands incorporating a diarylurea scaffold and triazole linkers

A series of diarylurea ligands were designed to interact selectively with G-quadruplexes and were synthesised using copper(I) catalysed 'click' chemistry to incorporate the 1,4-substituted 1,2,3-triazole ring into the core of the ligands; the optimal ligands demonstrate a high degree of selective telomeric G-quadruplex stabilisation and are not cytotoxic in several cancer cell lines.

Stabilization of G-quadruplex DNA by highly selective ligands via click chemistry

A series of G-quadruplex stabilizing compounds have been prepared via click chemistry employing the Cu(I)-catalyzed Huisgen reaction. These compounds were shown to bind tightly to G-quadruplex DNA even in the presence of competing high concentrations of duplex DNA. Furthermore, a modified TRAP assay has shown that some of these compounds also inhibit telomerase at low micromolar concentration. Copyright
