The present report describes a new series of amide functionalized 20- and 30-aminomethylferrocene derived from ferrocenylmethylamine. The compounds 1a-5a and 1b-5b were characterized by microanalysis, 1H, 13C NMR, UV–visible, fluorescence, FTIR, thermogravimetric and crystallographic techniques. The X-ray analysis demonstrated the ability of these molecules to form various intermolecular hydrogen bonding interactions, as verified by Hirshfeld surface analysis. All the compounds were evaluated against MCF 7, IMR 32, HepG2 and immortal L132 cell lines by MTT assay and the results were compared with cisplatin. Interestingly, many compounds were very active against all the investigated cell lines and proved to be more potent as cytotoxic agents than cisplatin. The western blot, gene expression, mitochondrial membrane potential and flow cytometry study were used to investigate the mode of action of these derivatives as antitumor agents. The results showed apoptotic property of the compounds by modulating inflammatory pathway against human tumor cells of different origin. We performed the density functional theory calculations and molecular docking to rationalize the experimental results.

The emergence of antibiotic-resistant Mycobacterium Tuberculosis (Mtb) infections compels new treatment strategies, of which targeting trans-translation is promising. During the trans-translation process, the ribosomal protein S1 (RpsA) plays a key role, and the Ala438 mutant is related to pyrazinamide (PZA) resistance, which shows its effects after being hydrolysed to pyrazinoic acid (POA). In this study, based on the structure of the RpsA C-terminal domain (RpsA-CTD) and POA complex, new compounds were designed. After being synthesized, the compounds were tested in vitro with saturation transfer difference (STD), fluorescence quenching titration (FQT) and chemical shift perturbation (CSP) experiments. Finally, six of the 17 new compounds have high affinity for both RpsA-CTD and its Ala438 deletion mutant. The active compounds provide new choices for targeting trans-translation in Mtb, and the analysis of the structure-activity relationships will be helpful for further structural modifications based on derivatives of 2-((hypoxanthine-2-yl)thio)acetic acid and 2-((5-hydroxylflavone-7-yl)oxy)acetamide.

Based on our prior work, we reported the design, synthesis, and biological evaluation of fifty-two new triazolothiadiazine-based analogues of CA-4 and their preliminary structure-activity relationship. Among synthesized compounds, Iab was found to be the most potent derivative possessing IC50 values ranging from single-to double-digit nanomolar in vitro, and also exhibited excellent selectivity over the normal human embryonic kidney HEK-293 cells (IC50 > 100 μM). Further mechanistic studies revealed that Iab significantly blocked tubulin polymerization and disrupted the intracellular microtubule network of A549 cells. Moreover, Iab induced G2/M cell cycle arrest by regulation of p-cdc2 and cyclin B1 expressions, and caused cell apoptosis through up-regulating cleaved PARP and cleaved caspase-3 expressions, and down-regulating of Bcl-2. Importantly, in vivo, Iab effectively suppressed tumor growth of A549 lung cancers in a xenograft mouse model without obvious signs of toxicity, confirming its potential as a promising candidate for cancer treatment.

As an aspect of our ongoing research on developing novel antiproliferative agents, 31 new triazole–isoindoline hybrids bearing 3,4,5-trimethoxyphenyl moiety were synthesized and evaluated for their antiproliferative activity against four cancer cell lines (HepG2, HeLa, PC-3, and HCT116). Some compounds showed excellent potency, and compared to fluorouracil, the most promising compound 6s exhibited 5.8-, 4.3-, and 1.3- fold increase in activities against HeLa, HepG2, and PC-3 cell lines with IC50 values of 9.7, 10.7, and 16.8?μM, respectively. Moreover, structure–activity relationship studies indicated that a much shorter amide linkage and electron-withdrawing groups at phenyl ring of the acetamide fragment contribute to the antitumour activity.

Thirty phenolic ether derivatives of scopoletin modified at the 7-hydroxy position were synthesized, and their structures were confirmed by IR,1H-NMR,13C-NMR, MS and elemental analysis. Preliminary acaricidal activities of these compounds against female adults of Tetranychus cinnabarinus (Boisduval) were evaluated using the slide-dip method. The results indicated that some of these compounds exhibit more pronounced acaricidal activity than scopoletin, especially compounds 32, 20, 28, 27 and 8 which exhibited about 8.41-, 7.32-, 7.23-, 6.76-, and 6.65-fold higher acaricidal potency. Compound 32 possessed the the most promising acaricidal activity and exhibited about 1.45-fold higher acaricidal potency against T. cinnabarinus than propargite. Statistically significant 2D-QSAR model supports the observed acaricidal activities and reveals that polarizability (HATS5p) was the most important parameter controlling bioactivity. 3D-QSAR (CoMFA: q2 = 0.802, r2 = 0.993; CoMSIA: q2 = 0.735, r2 = 0.965) results show that bulky substituents at R4, R1, R2 and R5 (C6, C3, C4, and C7) positions, electron positive groups at R5 (C7) position, hydrophobic groups at R1 (C3) and R2 (C4), H-bond donors groups at R1 (C3) and R4 (C6) will increase their acaricidal activity, which provide a good insight into the molecular features relevant to the acaricidal activity for further designing novel acaricidal agents. Molecular docking demonstrates that these selected derivatives display different bide modes with TcPMCA1 from lead compound and they interact with more key amino acid residues than scopoletin. In silico ADME properties of scopoletin and its phenolic ether derivatives were also analyzed and showed potential to develop as good acaricidal candidates.

Based on our previous work, a series of novel 3-alkylsulfanyl-4-amino-1,2,4-triazole derivatives were designed, synthesized and evaluated for their antiproliferative activities. The results indicated that some compounds possessed significant antiproliferative activities against four cancer cell lines, HepG2, HCT116, PC-3, and Hela. Particularly, the most promising compound 8d displayed 184-, 18-, and 17-fold improvement compared to fluorouracil in inhibiting HCT116, Hela and PC-3 cell proliferation with IC50values of 0.37, 2.94, and 31.31 μM, respectively. Most interestingly, the compound did not affect the normal human embryonic kidney cells, HEK-293. Moreover, mechanistic investigation showed that the representative compound 8d induced apoptosis and blocked cell cycle in G2/M phase in Hela cells in a dose-dependent manner. These findings suggest that compound 8d may have potential to be developed as a promising lead for the design of novel anticancer small-molecule drugs.
