And the article was included in European Journal of Medicinal Chemistry in 2020.Application In Synthesis of 5-Chloro-2-methoxybenzoic acid This article mentions the following:

As our research focuses on anticancer drugs, a series of novel derivatives of flexicaulin A (I), an ent-kaurene diterpene, condensed with an aromatic ring were synthesized, and their antiproliferative activities against four human cancer cell lines (TE-1, EC109, MCF-7, and MGC-803) were evaluated. The activities of most of the new compounds were better than those of I. Compound II exhibited the best activity with an IC50 value reaching 0.13μM against oesophageal cancer cells (EC109 cells). The IC50 values for II in normal cells (GES-1 cells and HUVECs) were 0.52μM and 0.49μM, resp. Subsequent mechanistic investigations found that compound II can inhibit the proliferation of cancer cells and cell cloning. In addition, II could reduce the mitochondrial membrane potential, increase the apoptosis rate, and increase the ROS level in EC109 cells. Moreover, II can upregulate the expression of ROS/JNK pathway-related proteins (p-ASK1, p-MKK4, p-JNK, and p-Cjun (ser63)) and pro-apoptotic proteins (Bax, Bad, and Bim). In vivo experiments showed that II can inhibit tumor growth in nude mice. The mechanism involves an increase in protein expression in the ROS pathway, leading to changes in apoptosis-related proteins. In addition, compound II shows low toxicity. These results indicate that compound II holds promising potential as an antiproliferative agent. In the experiment, the researchers used many compounds, for example, 5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2Application In Synthesis of 5-Chloro-2-methoxybenzoic acid).

5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning.

And the article was included in Natural Product Research in 2019.COA of Formula: C18H37Cl This article mentions the following:

Oregano (Origanum vulgare L.) is a common aromatic plant used in Mediterranean and Asian Regions for treating respiratory diseases, painful menstruation, rheumatoid arthritis, etc. Recently its role as an anticancer plant has been suggested, although oregano has been never evaluated into adrenocortical tumor cell models. This study analyzed for the first time the anticancer effects of a crude extract of wild mountain oregano (Origanum vulgare L.) in SW13 and H295R cell lines. The crude extract was characterised by GC/MS and the toxic effects of oregano were first analyzed by brine shrimp lethality assay. Our findings demonstrated that oregano decreased cell viability, survival, modified cell cycle and induced cell death (through necrotic process) and that the effects can be attributed to a blockade of MAPK and PI3 K/Akt pathways. These results suggest that oregano extract exerts anticancer activities in adrenocortical tumor cell lines, providing evidence for further research in higher models. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2COA of Formula: C18H37Cl).

1-Chlorooctadecane (cas: 3386-33-2) belongs to organic chlorides.

New kinds of Pd-coordinating azo-based liquid crystalline polysilsesquioxanes, Pd-H-FBA and Pd-C-FBA, have been synthesized first by hydrosilylation reactions of a vinyl-terminated mesomorphic azo compound with ladder-like homopolyhydrosilsesquioxane (H-T) and copolymethylhydrosilsesquioxane (MH-T) to produce fishbone-like, azo-based liquid crystalline polysilsesquioxanes H-FBA and C-FBA, resp., followed by a further ortho-palladation reaction with palladium chloride. The mesomorphic properties have been investigated by DSC, optical polarizing microscopy and temperature-variable x-ray diffraction. Their clearing temperatures, T_cl, are much higher and the mesophase ranges, ΔT, are much wider than those of the corresponding comb-like polymers with a single main chain,i.e., by more than 100°. This indicates that the double main chain structures of the title polymers have a pos. effect on mesomorphic properties. The influence of the content of Pd²⁺ ions on the liquid crystallinity is also discussed.

Loading concentrations of these four compounds were afterwards tested for cell viability and cytotoxicity on MCF7 human breast cancer cells, revealing a time- and dose-dependent decrease of active metabolizing cells over the time of the culture (0-72 h), starting from a concentration of 100μM. Likewise LDH released raised up to 40% at early time of exposures (24 h). Finally, the docking study showed that the best active compounds efficiently bound in the active site of the aromatase; high values of HBD and low levels of HBA are the principal requirement evidenced by the QSAR model.

Angiogenesis is modulated by a multitude of pro-angiogenic factors including VEGFR-2, Tie-2, and EphB4. Moreover, their crosstalk also had been well elaborated. We have identified several diarylurea-based VEGFR-2 inhibitors as potential anti-angiogenesis agents.
