Here we review the results of experimental and clinical observations concerning the gonadotoxic effect of antitumor chemotherapy. Previous experiments showed that antiblastic preparations with various mechanisms of cytostatic action produce damage to the sex glands that differs in the severity, stage of manifestation, and period of reparative regeneration. These differences are related to different sensitivity of epitheliocytes in the testes and structural and functional elements in the ovaries. Morphological changes in the gonads are accompanied by dysfunction of the reproductive system. We compared damages to the reproductive system and its individual components produced by various antitumor preparations. The offspring was examined after cytostatic treatment of one of the parent animals.

Purpose: Colorectal cancer (CRC) is the second leading cause of cancer-related deaths worldwide. Oxaliplatin (OXA) is currently the primary chemotherapeutic agent for CRC, but its efficacy is limited by the tumor microenvironment (TME). Here, we present a combined approach of chemotherapy and TME modulation for CRC treatment.

The present study aimed to optimize a mouth-dissolving film (MDF) made from Pongamia pinnata stem bark extract to increase patient compliance and accelerate oral disease therapy. Several stem bark extracts were prepared, and karanjin was used as an herbal marker for the extracts. The ethanolic extract showed the maximum yield (12.

Esophageal cancer (EC) is one of the most common highly malignant tumors of the digestive system, with a poor prognosis under current treatment regimens. Nucleolin (NCL) is overexpressed in many tumors, and drugs specifically targeting NCL may offer a promising strategy for treating esophageal cancer. Here, we designed and prepared a novel aptamer-conjugated drug targeting NCL by AS1411 aptamer-human serum albumin (HSA)-the apoprotein of lidamycin (LDP)-active enediyne chromophore (AE), in order to achieve targeted treatment of esophageal cancer.

The labile tautomerism of -unsubstituted 5-acyl-4-pyridones, which exist in the form of 4-pyridone or 4-hydroxypyridine depending on the solvent, has been demonstrated. This equilibrium determines the reactivity of pyridones and their ability to undergo substitution reactions of the OH group. A regioselective and convenient method for the construction of functionalized pyrazolo[4,3-]pyridines (30-93%) based on the intramolecular amination reaction of 4-pyridones with hydrazines has been developed.

Background: Selpercatinib, a selective RET kinase inhibitor, is approved for treating various cancers with RET gene mutations such as RET-rearranged thyroid cancer and non-small cell lung cancer. The presence of process-related and degradation impurities in its active pharmaceutical ingredient (API) can significantly affect its safety and effectiveness. However, research on detecting these impurities is limited.
