Biological Activity of Bicyclic Monoterpene Alcohols

The present paper aims to study the biological properties of a series of bicyclic monoterpene alcohols. Firstly, we tested the obtained compounds for fungicidal activity against clinical and reference strains of microscopic fungi. Next, we determined the minimum inhibitory concentration of these compounds comparing to other drugs widely used in practical medicine (fluconazole, terbinafine). At this stage, we found that (−)-myrtenol (47 MIC and 23.5 μg/ml) exhibits the most promising activity against filamentous and yeast fungi, respectively. Then, we have studied the membrane-protective and antioxidant activities of the obtained compounds and found out that (−)-cis-verbenol and (−)-myrtenol exhibit the highest activity on the model of erythrocytes oxidative hemolysis. Interestingly, among all the studied bicyclic monoterpene alcohols, the alcohols of the pinane series have been found to be the most promising. The obtained results from the present study suggest that (−)-myrtenol would be a leading compound for further studies in terms of possible practical application

Safety and Effectiveness of Intraarticular Administration of Adipose-Derived Stromal Vascular Fraction for Treatment of Knee Articular Cartilage Degenerative Damage: Preliminary Results of a Clinical Trial

The incidence of knee osteoarthritis tends to increase every year and constitutes more than 83% of overall OA morbidity. Moreover, the OA morbidity among younger patients is also increasing. However, currently available treatment methods do not provide quite satisfactory outcomes. Purpose of the study - to evaluate safety and efficacy of intraarticular introduction of autologous adipose-derived stromal vascular fraction for treatment of knee osteoarthritis. Material and methods. By the moment of writing the present report, 28 patients were included into the study. All patients underwent tumescent liposuction under local anesthesia. The stromal vascular fraction was isolated from lipoaspirate within 1,5 hours after harvesting and subsequently injected into the articular cavity. Follow-up period was 6 months after injections. The authors report on efficacy data of 10 patients who completed the study according to protocol and safety data of all 28 patients. Efficacy was evaluated basing on laboratory assessments and patient's subjective assessment by validated questionnaires. Results. Neither adverse reactions no adverse events were observed. Significant decrease of pain severity by VAS was noted in one week after injection and pain score continued decreasing during the whole follow up period. The increase of KOOS score was noted starting on the fifth week after injection. KSS part 1 score increased in 8 weeks, KSS part 2 score - in 6 months after injection. Physical health, assessed with SF-36 questionnaire significantly improved in 2 and 6 months after the procedure. There was a clear trend towards improvement of mental health. Conclusion. Preliminary results of clinical study suggest intraarticular injection of autologous adipose-derived stromal vascular fraction to be a safe and efficient method of the treatment of knee osteoarthritis

Доля данной патологии составляет 83% от общей заболеваемости остеоартрозом. Результаты лечения существующими методами не вполне удовлетворительные. Цель исследования - оценить безопасность и эффективность внутрисуставного введения аутологичной стромально-васкулярной фракции клеток жировой ткани для лечения остеоартроза коленного сустава. Материал и методы. В исследование включено 28 пациентов. В условиях дневного стационара у каждого пациента забирали жировую ткань (шприцевая липосакция под местной анестезией), из которой в течение 1,5 ч выделяли стромально-васкулярную фракцию клеток и вводили в полость сустава. Наблюдение за пациентами осуществляли в течение 6 мес. после введения клеточного продукта. Нами представлены данные об эффективности, полученные при анализе индивидуальных регистрационных карт 10 больных, которые в соответствии с протоколом завершили участие в исследовании, и данные о безопасности, полученные для всех 28 пациентов. эффективность оценивали при помощи инструментальных методов обследования, а также валидированных вопросников. Результаты. Ни у одного больного не было выявлено нежелательных явлений или реакций. Через неделю после введения стромально-васкулярной фракции клеток жировой ткани отмечалось снижение болевого синдрома, которое продолжалось на протяжении всего периода наблюдения. Оценка качества жизни пациентов по шкале KOOS выявила улучшение качества жизни начиная с четвертой недели после внутрисуставного введения клеток. при клинической оценке функции коленного сустава с использованием части 1 вопросника KSS установлено повышение суммы баллов через 8 нед., а по части 2 вопросника KSS - через 6 мес. после введения клеточного продукта. при оценке качества жизни с помощью вопросника SF-36 выявлено улучшение физического компонента здоровья, статистически значимое на 2-м и 6-м мес. исследования. Не выявлено статистически значимого улучшения психологического компонента здоровья, однако наблюдается отчетливая тенденция к улучшению данного показателя. Выводы. предварительные результаты клинического исследования свидетельствуют о безопасности и эффективности внутрисуставного введения аутологичной стромально-васкулярной фракции клеток жировой ткани для лечения остеоартроза коленного сустава

Design, Spectral Characteristics, and Possibilities for Practical Application of BODIPY FL-Labeled Monoterpenoid

This article describes the design and biological properties of a BODIPY FL-labeled monoterpenoid BF2-meso-(4-((1″R)-6″,6″-dimethylbicyclo[3.1.1]hept-2″-ene-2″)yl-methoxycarbonylpropyl)-3,3′,5,5′-tetramethyl-2,2′-dipyrromethene conjugate (BODIPYmyrt). The fluorophore was characterized using X-ray, NMR, MS, and UV/vis spectroscopy. The conjugate exhibits a high quantum yield (to ∼100%) in the region 515-518 nm. BODIPYmyrt effectively penetrates the membranes of the bacterial and fungal cells and therefore can be used to examine the features of a broad spectrum of Gram-positive and Gram-negative bacteria and pathogenic fungi as well. Moreover, BODIPYmyrt exhibits a moderate tropism to the subcellular structures in mammalian cells (e.g., mitochondria), thereby providing an attractive scaffold for fluorophores to examine these particular organelles
