An efficient synthesis of the -derived diarylheptanoids, viz., enantiomers of a β-hydroxyketone () and an α,β-unsaturated ketone () was developed starting from commercially available eugenol. Among these, compound showed a superior antiproliferative effect against human breast adenocarcinoma MCF-7 cells. Besides reducing clonogenic cell survival, compound dose-dependently increased the sub G1 cell population and arrested the G2-phase of the cell cycle, as revealed by flow cytometry. Mechanistically, compound acts as an intracellular pro-oxidant by generating copious amounts of reactive oxygen species. Compound also induced both loss of mitochondrial membrane potential (MMP) as well as lysosomal membrane permeabilization (LMP) in the MCF-7 cells. The impaired mitochondrial and lysosomal functions due to reactive oxygen species (ROS)-generation by compound may contribute to its apoptotic property.

Asiatic acid (AA) was used as the lead compound and 22 inhibitors of specificity protein 1 (Sp1) were designed and synthesized with modification at A ring and C-28 position of AA, whose structures were confirmed by HRMS, H NMR and C NMR. The growth inhibitory effects of Asiatic acid derivatives on human breast cancer cells (MCF-7) and cervical cancer cells (Hela) were determined by tetramethyl azole salt (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, MTT) colorimetric assay. The results showed that all of these compounds inhibited the proliferation of HeLa and MCF-7 cells, and all the derivatives showed stronger tumor cytotoxicity than AA, among which compounds I, II, and III were comparable to the positive control drug cisplatin.

A series of novel matrine derivatives incorporating thiosemicarbazide moieties was designed and synthesized. The in vitro cytotoxicity of these compounds was evaluated against four human cancer cell lines: MCF-7, HepG2, SGC-7901, and A549. Results demonstrated that their cytotoxic activity was significantly higher than that of matrine.

In the field of theranostics, triaminophenaziniums are promising molecules due to their intrinsic properties such as an absorbance beyond 500 nm associated with large molar extinction coefficients, high fluorescence quantum yields, as well as phototoxicity. This study explored how three triaminophenazinium salts relate in structure and activity, highlighting their potential as theranostic agents. The nature of the moiety in position 2 of the dyes was varied from H, to -CH or -Bu.

Proteolysis-targeting chimeras (PROTACs) have emerged as a powerful modality for selectively degrading intracellular proteins via the ubiquitin-proteasome system. However, their development is often hindered by the limited availability of high-affinity small-molecule ligands, particularly for challenging targets, such as transcription factors. Aptamers─synthetic oligonucleotides with high affinity and specificity─offer a promising alternative as target-binding modules in the PROTAC design.
