Immunometabolic disorders in the pathogenesis of systemic lupus erythematosus.

Systemic lupus erythematosus is a chronic autoimmune disease connected with complex and unclear disorders of the immune system, which causes inflammation of body tissues and internal organs. It leads to the formation of anti-nuclear antibodies (ANA) and immune complexes. Numerous immune system disorders and dysfunctions in the biochemical processes can occur in the course of the disease, and a wide range of abnormalities associated with cellular respiratory processes and mitochondrial function have been documented.

New tacrine-acridine hybrids as promising multifunctional drugs for potential treatment of Alzheimer's disease.

The synthesis, biological tests, and computer modeling of a series of novel promising tacrine hybrids for the therapy of Alzheimer's disease are reported. Firstly, new tacrine-acridine hybrids with different carbon linker lengths were synthesized. Secondly, all the compounds were tested in vitro for their ability to inhibit acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzyme activity.

Nucleotide Excision Repair Capacity and XPC and XPD Gene Polymorphism Modulate Colorectal Cancer Risk.

Background: Colorectal cancer (CRC) is leading malignant tumors to occur mainly in industrialized countries, where it exhibits one of the highest mortality rates. Up to 80% of all CRCs characterize a chromosomal instability (CIN) phenotype. The main challenge faced by scientist is to reveal the mechanism of CIN development.

Novel tetrahydroacridine and cyclopentaquinoline derivatives with fluorobenzoic acid moiety induce cell cycle arrest and apoptosis in lung cancer cells by activation of DNA damage signaling.

Lung cancer is still the leading cause of cancer-related death worldwide, indicating a necessity to develop more effective therapy. Acridine derivatives are potential anticancer agents due to their ability to intercalate DNA as well as inhibit enzymes involved in replication and transcription. Recently, we have evaluated anticancer activity of 32 novel acridine-based compounds.
