A Comprehensive Study on Phytochemical Contents, Isolation and Antioxidant Capacities in wild mind, Mentha longifolia subsp. typhoides var. typhoides PH. Davis

The current study is to determine variation in vitro antioxidant activities and chemical contents of different extraction solvents in aerial parts of wild M. longifolia subsp. typhoides var. typhoides taxons from Turkey. The chemical and volatile compounds of M. longifolia were investigated with HPLC-TOF/MS and GC/MS. The highest total phenolic and flavonoid contents were found as 28.27 and 25.42 mg from R6W, respectively. Hesperidin, neohesperidin, taxifolin, fumaric acid, chlorogenic acid, naringin, 4-hydroxybenzoic acid, caffeic acid, protocatechuic acid and syringic acid were determined in all extracts. The linalool, menthone, isomenthone, piperitoneoxide, pulegone, thymol, caryophyllene and caryophylleneoxide were major components in volatile compounds. The highest activities were observed significantly (p < 0.01) from R6M, R6W, R10EA and R5M in total antioxidant, superoxide-scavenging, metal-chelating and inhibition of lipid peroxidation activities, respectively. The isolated menthone (96.00%) was exhibited the higher inhibition of lipid peroxidation than standards. The results validate that M. longifolia possesses as a source of antioxidant potential for medicinal and foods

Synthesis and bioactivity studies of 1-aryl-3-(2-hydroxyethylthio)-1-propanones

A series of Mannich bases having piperidine moiety were reacted with 2-mercaptoethanol, leading to 1-aryl-3-piperidine-4-yl-1-propanone hydrochlorides. The cytotoxicity and carbonic anhydrase inhibitory activities of these new compounds were evaluated. Among the compounds, only one derivative, nitro substituent bearing EU9, showed an effective cytotoxicity, although weak tumor specificity against human oral malignant versus nonmalignant cells. The compound induced apoptosis in HSC-2 oral squamous cell carcinoma cells, but not in human gingival fibroblast. Chemical modifications of this lead are thus necessary to further investigate it as a drug candidate and to obtain compounds with a better activity profile

The diagnostic and prognostic value of red cell distribution width in cardiovascular disease, current status and prospective

The red blood cell distribution width (RDW) is an index of the heterogeneity of circulating red blood cell size, which along with other standard complete blood count (CBC) parameters are used to identify hematological system diseases. Besides hematological disorders, several clinical studies have shown that an increased in the RDW may be associated with other diseases including acute pancreatitis, chronic kidney disease, gastrointestinal disorders, cancer, and of special interest in this review, cardiovascular disease (CVD). The diagnostic and prognostic value of RDW in different CVD (acute coronary syndrome, ischemic cerebrovascular disease, peripheral artery disease, atrial fibrillation, heart failure, and acute ischemic stroke) has been reviewed in this article, to provide an understanding how its measurement may be applied to improve the management of these conditions.Keywords: RDW, Biomarker, Cardiovascular disease

Inhibitory Effect of 6,7-dimethoxy-5-hydroxyflavone on Human Cervix Carcinoma in Vitro

Natural products derived from plants play a significant role in drug discovery due to the revealing a large variety of pharmaceutical effects. Kickxia spuriawas collected from Bingol, Turkey. Aerial parts of the plant were boiled in water for 2 h then extracted with ethyl acetate. After evaporation of the solvent by rotary evaporator, the extract was subjected to column chromatography to yield the compound identified as 6,7-dimethoxy-5-hydroxyflavone by spectroscopic method including 1D-, 2D-NMR, LC-TOF/MS. Antiproliferative activity of isolated compound was tested against HeLa (human cervix carcinoma) cell lines by xCELLigence assay, and found out that the compound exhibited excellent activity

Synthesis of mannich bases by two different methods and evaluation of their acetylcholine esterase and carbonic anhydrase inhibitory activities

Background: Mannich bases are an important compounds in medicinal chemistry. They have wide range of biological activities including carbonic anhydrase (CA) inhibitory and acetylcholine esterase inhibitory (AChE) activities. Objective: It was aimed to synthesize Mannich bases, 1-aryl-3-(morpholin-4-yl/piperidin-1-yl)-1propanone hydrochloride, by microwave irradiation and conventional heating methods to compare the methods in terms of reaction times and yields and to investigate their inhibitory effects on AChE enzyme and CA isoenzymes. Method: Mannich bases were synthesized using conventional heating and microwave irradiation methods under different reaction conditions. Inhibitory effects of the compounds on CA isoenzymes and AChE were evaluated according to literature procedure. Results: IC50 and Ki values of the compounds were evaluated against hCA I, II and AChE. The compounds had more potent or equal Ki values with the references used. Conclusion: This study makes an important contribution to the Mannich base library in terms of synthetic strategy. According to IC50 or Ki values the compounds 6 in Series A with morpholine and and 15 in Series B with piperidine towards both hCA I and/or II isoenzymes and the compounds 4 in Series A and 11, 13, 14, 15, 16, and 18 in Series B towards AChE seemed the leader compounds of the study
