Summary: In this study, two series of 7-chloroquinoline-sulfonamide hybrids were synthesized and evaluated for their antimalarial activity. The compounds demonstrated multiple modes of action and significant activity against Plasmodium falciparum. The most promising hybrids could be potential candidates for next-generation antimalarials.

Summary: A library of functionalized quinolines has been prepared through magnesiation of 7-chloroquinolines under mild conditions. The synthesized 4-carbinol quinolines showed interesting antiproliferative properties, with their hydroxyl group serving as a suitable amino group bioisostere. The study also reported a two-step approach for optically active derivatives.

Summary: Four new TPP conjugates of 1,2,3-triazolyl nucleoside analogues were synthesized and evaluated for their antibacterial, antifungal, and cytotoxic activities. Two lead compounds showed high antibacterial activity against MRSA strains resistant to Ciprofloxacin and Amoxicillin, as well as high cytotoxicity against human cancer cell lines. The bactericidal effect of the lead compounds was not caused by a violation of the integrity of the cytoplasmic membrane of bacteria and their cytotoxic activity is likely associated with apoptosis induction and cell cycle arrest.

Summary: New cytotoxic derivatives based on the lupane scaffold were synthesized and tested for their activity against cancer cell lines and normal fibroblasts. Some derivatives showed cytotoxic activity against cancer cells but were also toxic to normal cells. One compound exhibited selectivity towards tumor cells without affecting the growth of normal cells.

Summary: The novel pyrrolizidinylmethyl derivative MG3 showed excellent antimalarial activity against drug-resistant parasites, both in vitro and in vivo. The compound exhibited comparable or better efficacy than chloroquine and other quinolines in rodent models of malaria, and its pharmacological profile met the requirements for further development.

Summary: This study demonstrates that aggregation of fluorescent quantum dot (QD) linked with cucurbiturils (CBs) can be broken-up by including guest molecules, while retaining CBs adsorbed on the surface. At the same time, the QD surface can be modified by the functional tail of the guest, enabling a non-covalent, click-like modification of nanoparticles in aqueous solution. This approach provides divergent routes for nano-architectures with rich functionalities for theranostics and photonics in aqueous systems.

Summary: The design of prodrugs is an important strategy for selective anti-cancer therapies. Glycoconjugates, which consist of three basic building blocks, are frequently used for targeting tumor-specific markers. Research shows that the presence of all three building blocks is necessary for the full activity of glycoconjugates. Additionally, targeted drug delivery using polymer nanocarriers improves the selectivity and effectiveness of the tested compounds.

Summary: The study focuses on investigating the aggregation and complexing properties of calixarenes as potential DNA condensation agents for gene delivery. Triazole derivatives of calix[4]arenes 7 and 8 containing monoammonium fragments were synthesized and characterized. The interactions between these compounds and calf thymus DNA were studied, and the cytotoxic properties against cancerous cells were evaluated. Compound 4 showed the highest toxic effect on MCF7 breast adenocarcinoma.

Summary: A novel inulin derivative (3) bearing 1,2,3-triazole and diphenyl phosphate was successfully synthesized using CuAAC Click chemistry, showing significantly enhanced antioxidant activity compared with inulin. In vitro evaluation revealed strong radical scavenging abilities of the derivative, particularly against hydroxyl radicals and superoxide radicals. The synthetic strategy may offer an effective approach for preparing new inulin antioxidant biomaterials.
