Gastric cancer represents a significant health burden worldwide. Previously, inspired by the traditional Chinese medicine Wu-Chu-Yu to treat the spleen and stomach system for thousands of years, we identified N14-phenyl substituted evodiamine derivatives as potential antitumor agents with favorable inhibition on Top1. Herein, structural optimization and structure-activity relationship studies (SARs) led us to discovering a highly active evodiamine derivative compound 6t against gastric cancer. Further anti-tumor mechanism studies revealed that compound 6t played as the inhibition of topoisomerase 1 (Top1), effectively induced apoptosis, obviously arrested the cell cycle at the G2/M phase, and significantly inhibited the migration and invasion of SGC-7901 and MGC-803 cell lines in a dose-dependent manner. Moreover, the compound 6t was low toxicity in vivo and exhibited excellent anti-tumor activity (TGI = 70.12%) in the MGC-803 xenograft models. In summary, compound 6t represents a promising candidate as a potential chemotherapeutic agent against gastric cancer.

Natural products are important sources for the development of therapeutic medicine, among which evodia fruit has a wide range of medicinal properties in traditional Chinese medicine. Evodiamine, the main active component of evodia fruit, has various anti-cancer effects and has been proved to be a Topo inhibitor. From our previous attempts of modifying evodiamine, we found that the N14 phenyl substituted derivatives had showed great anti-tumor activity, which prompted us to further explore the novel structures and activities of these compounds. Compound 6f, as a N14 3-fluorinated phenyl substituted evodiamine derivative, showed a certain inhibitory activity against Topo I at 200 μM. By studying its anti-tumor effects in vitro, compound 6f could inhibit proliferation and induce apoptosis, as well as arrest the cell cycle of HGC-27 and HT-29 cell lines at G2/M phase in a concentration-dependent manner. Moreover, compound 6f could inhibit the migration and invasion of HGC-27 cell lines. Meanwhile, compound 6f could induce apoptosis of HGC-27 cells by inhibiting PI3K/AKT pathway. Overall, this work demonstrated that the N14 phenyl-substituted evodiamine derivatives had a good inhibitory effect on tumor cells in vitro, providing a promising strategy for developing potential anticancer agents for the treatment of gastrointestinal tumors.

With the increasing incidence of antibiotic resistance, new antibacterial agents having novel mechanisms of action hence are in an urgent need to combat infectious diseases caused by multidrug-resistant (MDR) pathogens. Four novel series of substituted 9-arylalkyl-10-methylacridinium derivatives as FtsZ inhibitors were designed, synthesized and evaluated for their antibacterial activities against various Gram-positive and Gram-negative bacteria. The results demonstrated that they exhibited broad-spectrum activities with substantial efficacy against MRSA and VRE, which were superior or comparable to the berberine, sanguinarine, linezolid, ciprofloxacin and vancomycin. In particular, the most promising compound 15f showed rapid bactericidal properties, which avoid the emergence of drug resistance. However, 15f showed no inhibitory effect on Gram-negative bacteria but biofilm formation study gave possible answers. Further target identification and mechanistic studies revealed that 15f functioned as an effective FtsZ inhibitor to alter the dynamics of FtsZ self-polymerization, which resulted in termination of the cell division and caused cell death. Further cytotoxicity and animal studies demonstrated that 15f not only displayed efficacy in a murine model of bacteremia in vivo, but also no significant hemolysis to mammalian cells. Overall, this compound with novel skeleton could serve as an antibacterial lead of FtsZ inhibitor for further evaluation of drug-likeness.

In continuation of our efforts to develop new drugs with antibacterial properties we have synthesized and evaluated new 1,2,3-triazole derivatives from acridone. The synthetic approach was started by the preparation of acridone skeleton through the Ullman condensation of 2-bromobenzoic acid and aniline derivatives. Subsequently, acridone nucleus was functionalized with propargyl bromide. Then, a click reaction of the latter compound and aromatic azides led to the formation of the title compounds in good yields. The synthesized compounds were screened for their in vitro antibacterial activity against one gram-positive bacteria S. aureus and three gram-negative bacteria P. putida, K. pneumoniae and E. coli. Among the synthesized compounds, 2-methyl-10-((1-(o-tolyl)-1H-1,2,3-triazol-4-yl)methyl)acridone (4e) had the most potent inhibitory activity against S. aureus with MIC = 10.1 μg/mL. Then, in silico docking studies were used in order to understand the binding interactions and mode of action of these compounds.

The YAP-TEAD transcriptional complex is responsible for the expression of genes that regulate cancer cell growth and proliferation. Dysregulation of the Hippo pathway due to overexpression of TEAD has been reported in a wide range of cancers. Inhibition of TEAD represses the expression of associated genes, demonstrating the value of this transcription factor for the development of novel anti-cancer therapies. We report herein the design, synthesis and biological evaluation of LM98, a flufenamic acid analogue. LM98 shows strong affinity to TEAD, inhibits its autopalmitoylation and reduces the YAP-TEAD transcriptional activity. Binding of LM98 to TEAD was supported by 19F-NMR studies while co-crystallization experiments confirmed that LM98 is anchored within the palmitic acid pocket of TEAD. LM98 reduces the expression of CTGF and Cyr61, inhibits MDA-MB-231 breast cancer cell migration and arrests cell cycling in the S phase during cell division.

In this work, novel N-acylhydrazone derivatives from acridone have been synthesized by condensation of 9-oxoacridin-10(9H)-yl)acetohydrazide with various aldehyde and ketone. The structures of these novel compounds were elucidated by 1H NMR, 13C NMR, IR and mass spectroscopy. The NMR data shows two conformations (E, trans and E, cis) due to N–C(O) bond rotation, the conformations of synthesized compounds have been investigated by different NMR methods. The rotational barriers around N–C(O) bond for compound 5a was measured in DMSO using dynamic NMR spectroscopy, this result was confirmed by DFT calculations at B3LYP/6–31 G (d) level in DMSO.

The present study was carried out in an?attempt to synthesize a new class of potential antibacterial agents. In this context, novel isoxazoles were synthesized and evaluated for their potential antibacterial behavior against four pathogenic bacterial strains. The synthesized compounds exhibited moderate-to-good antibacterial activity against these strains. The highest antibacterial activity was observed against the Escherichia coli strains, particularly for compounds 4a and 4e with phenyl and para-nitrophenyl groups on the isoxazole–acridone skeleton;?they showed promising minimum inhibitory concentration values of 16.88 and 19.01 μg/ml, respectively, compared with the standard drug chloramphenicol (22.41 μg/ml). The synthesized compounds were subjected to in silico docking studies to understand the mode of their interactions with the DNA topoisomerase complex (PDB ID: 3FV5) of E. coli. The molecular docking results showed that compounds 4a–l occupy the active site of DNA topoisomerase (PDB ID: 3FV5), stabilized via hydrogen bonding and hydrophobic interactions, which may be the reason behind their interesting in vitro antibacterial activity.

In this study, a new isoxazoline derived from acridone, 10‐{[3‐(4‐chlorophenyl)‐4,5‐dihydro‐1,2‐oxazol‐5 yl]methyl} acridone (3) was successfully synthesized and characterized by FT-IR, 1H NMR, 13C NMR and HRMS. The preparation of compound (3) was achieved by 1,3-dipolar cycloaddition reaction between 4?chloro-N-hydroxybenzimidoyl chloride and 10-allylacridone using environment friendly methods. In an effort to complete the chemical structure description of the synthetized compound, Density Functional Theory (DFT) was applied using Gaussian09 and Gaussian view5 programs. The theoretical calculations were used as a compliment to the experimental studies. The computing of geometric parameters, optimization energies, frontier molecular orbital energies, Molecular surface electrostatic potential (MESP) and Mulliken charges were calculated using DFT/B3LYP method with 6–31G(d,p) as basis set. The Infrared vibrational frequencies and 1H and 13C NMR chemical shifts were also calculated and their scaled values are in agreement with the experimental results.
