Correction of aberrant splicing of ELP1 pre-mRNA by kinetin derivatives - A structure activity relationship study.

Familial dysautonomia is a debilitating congenital neurodegenerative disorder with no causative therapy. It is caused by a homozygous mutation in ELP1 gene, resulting in the production of the transcript lacking exon 20. The compounds studied as potential treatments include the clinical candidate kinetin, a plant hormone from the cytokinin family.

Triterpenoid phthalimides as selective anti-cancer agents targeting mitochondrial apoptosis.

Starting from benzyl 30-oxobetulinate and 30-oxobetulin diacetate, substituted dienes were synthesized and subjected to Diels-Alder reaction, yielding a variety of triterpenoid phthalates, phthalimides, and related derivatives. A total of 55 new compounds were prepared and tested for in vitro cytotoxic activity against eight cancer cell lines and two non-cancerous cell lines. Four compounds with IC values of 5 μM or lower were selected for further investigation.

Novel triterpenoid pyrones, phthalimides and phthalates are selectively cytotoxic in CCRF-CEM cancer cells - Synthesis, potency, and mitochondrial mechanism of action.

A series of triterpenoid pyrones was synthesized and subsequently modified to introduce phthalimide or phthalate moieties into the triterpenoid skeleton. These compounds underwent in vitro cytotoxicity screening, revealing that a subset of six compounds exhibited potent activity, with IC values in the low micromolar range. Further biological evaluations, including Annexin V and propidium iodide staining experiment revealed, that all compounds induce selective apoptosis in cancer cells.

Novel 5-Substituted Oxindole Derivatives as Bruton's Tyrosine Kinase Inhibitors: Design, Synthesis, Docking, Molecular Dynamics Simulation, and Biological Evaluation.

Bruton's tyrosine kinase (BTK) is a non-RTK cytoplasmic kinase predominantly expressed by hemopoietic lineages, particularly B-cells. A new oxindole-based focused library was designed to identify potent compounds targeting the BTK protein as anticancer agents. This study used rational approaches like structure-based pharmacophore modeling, docking, and ADME properties to select compounds.

Lupane derivatives containing various aryl substituents in the position 3 have selective cytostatic effect in leukemic cancer cells including resistant phenotypes.

In this work, a large set of betulinic acid derivatives modified with various aromatic substituents at the position C-3 were prepared via Suzuki-Myiaura cross-coupling. All compounds were tested for their in vitro cytotoxic activity in 8 cancer and 2 healthy cell lines. Derivatives 6h, 6i, and 6o had the lowest IC in the CCRF-CEM cell line (0.
