In continuation with the previous work, a series of 5-hydroxy-2-amidomethoxy-1,4-naphthoquinones were prepared to establish the structure-activity relationship studies toward anticancer activity (IC50 in μM) against three cell lines; colo205 (colon adenocarcinoma), T47D (breast ductal carcinoma) and K562 (chronic myelogenous leukemia). Among the synthesized compounds, naphthoquinone amines, 5 (0.8; 0.6; 0.8), 14 (0.8; 0.6; 0.5) and the amine precursor, 4 (1.3; 0.3; 1.0) displayed potent anticancer activities. A tumor targeting drug delivery system was achieved by synthesizing the conjugate 6 (1.4; 0.5; 1.1) of naphthoquinone-amine 5 and Biotin which also proved its potency. Finally, to introduce polyamine conjugate, spermidine was attached with 2-amidomethoxy-1,4-naphthoquinone. The naphthoquinone-spermidine conjugate 27 (1.2; 1.7; 1.7) also retained the activity. Thus, potent naphthoquinone amines were explored and Biotin/polyamine conjugate was developed as tumor targeting drug delivery system.

Disseminated tumors lead to approximately 90% of cancer-associated deaths especially for hepatocellular carcinoma (HCC), indicating the imperative need of antimetastatic drugs and the ineffectiveness of current therapies. Recently polyamine derivatives have been identified as a promising prospect in dealing with metastatic tumors. Herein, a novel class of naphthalimide-polyamine conjugates 8a-8d, 13a-13c, 17 and 21 were synthesized and the mechanism was further determined. The polyamine conjugate 13b displayed remarkably elevated anti-tumor and anti-metastatic effects (76.01% and 75.02%) than the positive control amonafide (46.91% and 55.77%) at 5 mg/kg in vivo. The underlying molecular mechanism indicated that in addition to induce DNA damage by up-regulating p53 and γH2AX, 13b also targeted lysosome to modulate polyamine metabolism and function in a totally different way from that of amonafide. Furthermore, the HMGB1/p62/LC3II/LC3I and p53/SSAT/β-catenin pathways were mainly involved in the inhibition of 13b-induced HCC metastasis by targeting polyamine transporters (PTs) overexpressed in HCC. At last, 13b down-regulated the concentrations of Put, Spd and Spm by modulating polyamine metabolism key enzymes SSAT and PAO, which favored the suppression of fast growing tumor cells. Taken together, our study implies a promising strategy for naphthalimide conjugates to treat terminal cancer of HCC by targeting autophagy and tumor microenvironment with reduced toxicities and notable activities.

Naphthalene diimides (NDIs) have been widely used as scaffold to design DNA-directed agents able to target peculiar DNA secondary arrangements endowed with relevant biochemical roles. Recently, we have reported disubstituted linear- and macrocyclic-NDIs that bind telomeric and non-telomeric G-quadruplex with high degree of affinity and selectivity. Herein, the synthesis, biological evaluation and molecular modelling studies of a series of asymmetrically substituted NDIs are reported. Among these, compound 9 emerges as the most interesting of the series being able to bind telomeric G-quadruplex (ΔTm = 29 °C at 2.5 μM), to inhibit the activity of DNA processing enzymes, such as topoisomerase II and TAQ-polymerase, and to exert antiproliferative effects in the NCI panel of cancer cell lines with GI50values in the micro-to nanomolar concentration range (i.e. SR cell line, GI50= 76 nM). Molecular mechanisms of cell death have been investigated and molecular modelling studies have been performed in order to shed light on the antiproliferative and DNA-recognition processes.

Ianthelliformisamines A-C are a novel class of bromotyrosine-derived antibacterial agents isolated recently from the marine sponge Suberea ianthelliformis. We have synthesized ianthelliformisamines A-C straightforwardly by the condensation of (E)-3-(3,5-dibromo-4-methoxyphenyl)acrylic acid and the corresponding Boc-protected polyamine followed by Boc-deprotection with TFA. Further, using this reaction protocol, a library of their analogues (39 analogues) has been synthesized by employing 3-phenylacrylic acid derivatives and Boc-protected polyamine chains through various combinations of these two fragments differing in phenyl ring substitution, double bond geometry or chain length of the central spacer of the polyamine chain (shown in red color). All the synthesized compounds (ianthelliformisamines A-C and their analogues) were screened for antibacterial activity against both Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) strains. All synthetic analogues of ianthelliformisamine A showed bacterial growth inhibition against both strains (Escherichia coli and Staphylococcus aureus), having MIC values in the range of 117.8-0.10 μM, while none of the synthetic analogues of ianthelliformisamine C as well as the parent compound showed any detectable antibacterial activity. Interestingly, some of the synthetic analogues of ianthelliformisamines A and B exerted a bactericidal effect against both E. coli and S. aureus strains, decreasing viable bacterial count by 99% at concentrations as low as 2 × MIC.

A series consisting of ianthelliformisamimes A, B, and C as well as its synthetic analogues was prepared in high chemical yield, from 27 to 91%, using peptide coupling as the key step, and the compounds were evaluated for their in vitro antibiotic enhancer properties against resistant Gram-negative bacteria and clinical isolates. The mechanism of action of one of these derivatives against Pseudomonas aeruginosa when combined with doxycycline was precisely evaluated utilizing bioluminescence to measure ATP efflux and fluorescence to evaluate membrane depolarization.
