    INTRODUCTION: Hydrazones are compounds that can be considered as hydrogenated azo compounds or as derivatives of hydrazine (H2N-NH2) in the structure of which one hydrogen atom at each nitrogen is replaced by a hydrocarbon group. In this work, we discuss the possibilities for analysis of a newly synthesized hydrazone of the retinoid bexarotene with acetaminophen using infrared (IR) and ultraviolet-visible (UV-VIS) spectroscopy.Β Β AIM: The purpose of this study is to perform Fourier-transfrom infrared (FTIR) and UV-VIS spectroscopic analysis of a newly synthesized hydrazone of bexarotene.Β MATERIALS AND METHODS: А newly synthesized hydrazone derivative was obtained according to the basic scheme of synthesis of bexarotene analogs. Infrared spectra 500-4000 cm-1 were taken on a Bruker FTIR spectrometer using ATRβ€”a plug with a Smart iTR adapter. Spectra in the range 190–325 nm were recorded using UV-VIS spectrophotometer T60 UV with UVWin Software 6.0.Β RESULTS: After a detailed comparison of the data obtained in the IR analysis of the reagents and the newly obtained hydrazone, a similar position and intensity of the spectral bands are reported. However, there are displacements in spectral bands and significant differences corresponding to the structural changes that have occurred. Different values for the wavelength of maximum absorption were measured with a UV-VIS spectrophotometer for bexarotene, Paracetamol, and the newly synthesized compound.Β CONCLUSION: In order to confirm the data obtained by FTIR and UV-VIS spectroscopy, a further reversed-phase high-performance liquid chromatography-ultraviolet (HPLC-UV) analysis of the new hydrazone derivative should be performed

    INTRODUCTION: Retinoids are natural and synthetic compounds part of the family of polyisoprenoid lipids. These compounds are involved in several important physiological processes in the human body because of their ability to bind to different nuclear receptors. Retinoids are used in the therapy of some precancerous lesions, the treatment of acute promyelocytic leukemia (APL), T-cell lymphoma, and the prevention of malignancies in high-risk cancer groups. In this work we discuss the possibilities for analysis of the newly synthesized hydrazone of the retinoid bexarotene. Β AIM: The purpose of this study is to conduct FTIR spectral analysis of newly synthesized hydrazone of bexarotene.MATERIALS AND METHODS: Infrared spectra 500-4000 cm-1 were taken on a Bruker FTIR spectrometer using ATR - a plug with Smart iTR adapter.RESULTS: The infrared spectra of the newly synthesized compound were strikingly similar in the relative positions and intensities of the resulting peaks, confirming its close structural relationship with bexarotene. Despite the structural similarity, there were significant differences that point to the introduction of a substituent and the formation of a new hydrazone derivative.CONCLUSION: Β In order to confirm the data obtained by FTIR spectroscopy, a further reversed-phase HPLC-UV analysis of the new hydrazone derivative should be performed

    The increase in antibiotic resistance of microorganisms encourages the constant search for new compounds. Studies on the activity of hydrazones identify them as promising compounds for further microbiological research. The aim of the present study is to determine the antibacterial activity of newly synthesized 4-isopropyl-phenyl-methylidene-4- [1- (3,5,5,8,8-pentamethyl-6,7-dihydronaphthalen-2-yl) ethe- nyl] benzohydrazide, an analog of the antineoplastic preparation bexarotene. The assay was performed against clinical isolates of Escherichia coli and Staphylococcus aureus

    The dissertation deals with the preparation and characterization of the newly synthesized derivatives of the synthetic retinoid bexarotene. The continued and intensive study of the role of retinoids in the complex of differentiation, cell proliferation, and cellular growth processes determines the major potential for the using of retinoids (natural and synthetic) in the treatment of a number of abnormalities arising from abnormal cell development. Of particular interest is the possibility of their use in the treatment of neoplastic processes in the body. Bexarotene is a third-generation retinoid and is used in the treatment of T-cell skin cancer. In addition to its proven application in oncology, there are a number of data on the effects of neurological and autoimmune processes in the body. For the preparation of bexarotene derivatives, a three-step synthetic scheme has been developed. Involving the preparation of hydrazide and the subsequent interplay with carbonyl compounds to form the target hydrazones. Hydrazide-hydrazone compounds have attention in the last few decades because of the diverse pharmacological effects they possess. Hydrazones and their derivatives are known to exhibit a wide range of pharmacological effects such as antioxidant, anti-inflammatory, analgesic, antimicrobial, anthelmintic, anti-tuberculosis, etc. The development of the hydrazone class of compounds has made significant progress and many new aspects of application have been discovered. The resulting hydrazide hydrazones have been characterized structurally by instrumental methods including the use of infrared spectroscopy, 1H-NMR spectroscopy, and mass spectrometry. A validated HPLC method for the determination of bexarotene and its derivatives alone and in mixtures has been successfully applied. The antioxidant potential of the newly obtained bexarotene derivatives was evaluated using three different approaches - electron transfer capability - ABTS test, hydrogen atom transfer-DPPH test, as well as an electrochemical pathway. With the help of theoretical approaches, the possibilities for metabolic activation of bexarotene have been successfully identified, also its metabolites and new derivatives evaluated. The mechanisms by which the metabolites of the newly prepared compounds can potentiate liver damage through specific interactions with biological macromolecules (DNA and proteins) in the liver have been identified and summarized. The possibility of producing dermal metabolites has also been determined. // [BG] ДисСртационния Ρ‚Ρ€ΡƒΠ΄ Ρ€Π°Π·Π³Π»Π΅ΠΆΠ΄Π° ΠΏΠΎΠ»ΡƒΡ‡Π°Π²Π°Π½Π΅Ρ‚ΠΎ ΠΈ ΠΎΡ…Π°Ρ€Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ·ΠΈΡ€Π°Π½Π΅Ρ‚ΠΎ Π½Π° новосинтСзирани ΠΏΡ€ΠΎΠΈΠ·Π²ΠΎΠ΄Π½ΠΈ Π½Π° синтСтичния Ρ€Π΅Ρ‚ΠΈΠ½ΠΎΠΈΠ΄ бСксаротСн.

    IntroductionOver the last decade, there has been a significant increase in the scientific knowledge about cancer, which has accordingly led to the development and increase of interest in new medicines and therapeutic approaches with potential applications in oncology. Activity research and the identification of potential therapeutic and toxic effects of bexarotene-like structures underpin the development of new approaches to the treatment of a number of untreated diseases.This requires a further and in-depth study of the potential of newly synthesized compounds to produce active metabolites.AimIn view of the potential for dermal administration of bexarotene, the potential for toxic metabolism in the skin needs to be investigated.Materials and MethodsFor the purpose the OECD (Q) SAR Application Toolbox was used. It is a software application for evaluating the properties of chemicals based on their molecular structure.ResultsThe application of the model for predicting metabolic changes makes it possible to assess the risk based on the chemical structure of the compounds.ConclusionThe skin metabolic prediction of new hydrazones of third-generation retinoid bexarotene indicates that not one of them predicts binding to DNA or proteins
