The main objective of the present study was to develop and validate simple, precise, sensitive and accurate UPLC method for the estimation of asciminib in pure and dosage form. The UPLC method was developed by using Waters Acquity liquid chromatographic system and Zorbax Phenyl (100x1.0mm,1.7µm) column. The developed method was validated according to the international conference on harmonization (ICH) guidelines. The chromatographic separation of asciminib with good resolutions has been achieved by using the mobile phase acetonitrile: ammonium dihydrogen phosphate buffer (20:80 v/v) at a flow rate of 0.5 mL/min, injection volume of 5 µL, and at 242 nm wavelength. The validated method was found to be linear in the range of 4 - 60 µg/mL. The limit of detection (LOD) and limit of quantification (LOQ) for asciminib were found to be 0.4 and 0.12 µg/mL respectively. The % RSD was found to be less than 2 % revealing the precision of the developed method. Besides, the recovery rate was observed close to 100 % confirming the accuracy of the method. Minor alterations in the chromatographic conditions have revealed robustness and ruggedness of the developed method. The developed analytical method is simple, precise, sensitive, and reproducible which can be used for the estimation of asciminib.

Cytarabine (Cyt) (also known as cytosine arabinoside (ara-C)) used in the treatment of acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL). CYT applied in high doses for treatment can cause renal failure. Monitoring excreted urine drug levels can help kidney failure. For this reason, a method was developed and validated by HPLC-MSMS for urine CYT analysis, which is not included in the literature. In this study, a liquid chromatography (HPLC) with triple quadrupole Mass Spectrometric (MS/MS) method developed for the determination of Cyt from urine for toxicokinetic evaluation. Positive MRM mode selected for the quantification of Cyt. The product and major fragment ion for Cyt 244.0 > 112.0 m/z, for IS 198.0 > 152.0 m/z. The optimal MS parameters for Cyt and IS are as follows Fragmentor 80 V, 70 V, Collision energy, 6, 9 respectively. A novel simple, high-throughput and highly sensitive HPLC-MS/MS method was successfully developed and validated for the determination of Cyt from urine. The developed method has a simple one-step extraction method and a short run time (2.0 minutes) for analysis. The proposed method could be practical and reliable for excretion and toxicokinetic studies and as well as the Therapeutic Drug Monitoring study in humans without an invasive route for Cyt.

Cellulose was extracted from wood dust waste samples of Daniella oliveri and corn cobs by acetic acid and alkaline pretreatment methods, while microcrystalline cellulose (MCC) derivative was produced by acid hydrolysis in 2 M HCl. The samples were tested for pH, moisture content, swelling capacities and ash contents. The data obtained were compared with those of commercial MCCs found in the literature. The functional groups in the microcrystalline cellulose derivatives was confirmed by the Fourier transform infrared (FTIR) spectroscopic method with characteristic absorption bands of;–OH stretching at 3416 cm-1; C-H stretching at 2918 cm-1; -OH bending at 1377 cm-1; 1159 cm-1; and C-O-C pyranose ring skeletal vibrations at 1026-1033 cm-1. The crystallinity absorption bands appeared at 1436 and 850 cm-1. The characteristic morphological features were established by scanning electron microscopy (SEM). Furthermore, the crystallinity of the microcrystalline cellulose was further confirmed using the X-ray powder diffraction (X-RD) technique, which showed three main reflections at 2θ=14.70°, 22.09°, and 34.24°.These results supported that microcrystalline cellulose derivative as cellulose I type and the acid pretreatment did not affect the structure of the MCC. The crystallinity indices were 69.3 and 73.2%, respectively. Daniella Oliveri and corn cob microcrystalline cellulose are, therefore, potential materials for further processing.
采用醋酸法和碱法分别从大牛和玉米芯木屑废样中提取纤维素，在2 M HCl中酸水解制备微晶纤维素衍生物。测试了样品的pH值、水分含量、膨胀能力和灰分含量。所得数据与文献中发现的商用mcc数据进行了比较。用傅里叶变换红外光谱法确定了微晶纤维素衍生物中的官能团，其特征吸收带为:-OH，在3416 cm-1处拉伸;C-H在2918 cm-1处的拉伸;- 1377 cm-1弯曲1159 cm - 1;C-O-C吡喃糖环骨架振动在1026-1033 cm-1。在1436和850 cm-1处出现结晶性吸收带。通过扫描电镜(SEM)确定了其特有的形态特征。此外，利用x射线粉末衍射(X-RD)技术进一步证实了微晶纤维素的结晶度，该微晶纤维素在2θ=14.70°、22.09°和34.24°处有三个主要反射。这些结果表明微晶纤维素衍生物为I型纤维素，酸处理对MCC的结构没有影响。结晶度指数分别为69.3和73.2%。因此，Daniella Oliveri和玉米芯微晶纤维素是进一步加工的潜在材料。

Alzheimer's disease is the most common progressive neurodegenerative disorder that effects large population of society especially elderly people. Environmental and/or genetic factors contribute Alzheimer's disease to become a pivotal health problem but this relationship remains ambiguous. Globally growing prevalence of Alzheimer’s disease requires to understand cellular pathways that lead to Alzheimer’s disease and to develop new strategies for prevention and treatment. Elevated monoamine oxidase (MAO) enzymes activity with ages is associated with etiology of Alzheimer's disease. Inhibition of monoamine oxidase enzyme can protect from neuronal damage, thus it become one of the key pathway for management of Alzheimer’s disease. Using bioactive compounds from medicinal plants as potential monoamine oxidase inhibitors might be a better solution considering undesired side effects of synthetic drugs on human body. The purpose of this review is to implicate the importance of pharmacophore analysis which explains pharmacological properties of medicinal plants and interaction of bioactive compound from plants with MAO enzyme.

In this study, the anti-cholinesterase activities of different extracts of Achillea lycaonica, A. vermicularis and A. nobilis L. subsp. neilreichii (Kerner) Formanek species were examined and then trace elements (Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Cd, and Pb) of the plants were analysed by ICP-MS. The pharmacokinetic properties of the phenolic compounds of these plants previously analyzed by us and the ADME-Tox (absorption, distribution, metabolism, excretion, and toxicity) profiles of the trace elements we identified in this study were estimated. According to the data obtained, it was determined that all three plants showed high acetyl-cholinesterase inhibition activity. The concentration of trace elements was lower than that declared by WHO, except for the A. lycaonica. It was determined that V, Cr, Fe, Co, and As metals in A. lycaonica exceeded the limit values determined by WHO. According to ADMET estimates, it is thought that the toxic values of all three plants are not high, and therefore the use of A. nobilis and A. vermicularis plants does not pose any health risk but A lycaonica should be used carefully due to the heavy metals.

One of the ways of reducing metal corrosion and its devastating effects is by using organic corrosion inhibitors. This is because of the π-conjugation in their moieties, their ability to donate electrons to the metal’s vacant d-orbitals, and their low lying LUMO orbitals for accepting electrons as well from the metal, all these improve their adsorption on the metal surface. (E)-5-((4-benzoylphenyl)diazenyl)-2-hydroxybenzoic acid (AD4) was synthesized via the coupling reaction of p-aminobenzonephenone and Salicylic acid, characterized via FTIR, UV/Vis, 1H-NMR, and 13C-NMR spectroscopy. The melting point of AD4 is 103oC–106oC indicating that it is thermally stable and pure. Gravimetric and potentiodynamic polarization techniques were employed to obtain the corrosion rates (Cr) and percentage inhibition efficiency (%IE) at different concentrations of the inhibitor and at different temperatures. The thermodynamic parameters like Enthalpy, ∆Hoads, Entropy, ∆Soads and free energy of adsorption (∆Gads) of Adsorption were calculated. The Langmuir adsorption isotherm was used to describe the adsorption of AD4 molecules on mild steel. Quantum mechanical calculations were employed to calculate the electronic properties and global reactivity descriptors of AD4. The theoretical results are broadly consistent with experimental results. From the results obtained AD4 could be used as a corrosion inhibition agent in the oil and gas industries.

In this study, the use of calcined eggshell (CE) as an adsorbent in removing Victoria Blue R (VBR) dyestuff from the solution medium was investigated. For this purpose, pH, interaction time, adsorbate concentration, amount of adsorbent, and salt effect parameters were studied to determine the appropriate adsorption conditions. The highest adsorption yield was obtained at pH 2, 2.0 g/L adsorbent, and a stirring time of 5 minutes. 97% of the dye was removed under optimum adsorption conditions. The results obtained from the experimental studies showed that the adsorption mechanism is compatible with the pseudo-second-order kinetic model and the Langmuir isotherm model. SEM and IR analysis were performed for the characterization of CE.
