Three groups of novel analogs of combretastatin-A4 (CA-4), viz., the N1-phenyl-pyrazoline (5a–e), N1-alkyl acetylated pyrazoline (6a–c), and N1-phenyl acetylated pyrazoline (7a–g) were designed, and synthesized in good yield. The structure of the compounds was confirmed by spectroscopic techniques. All the compounds were evaluated for their in vitro anticancer (MCF-7 cell line), antioxidant (DPPH, NO, SOR, and H2O2), and anti-inflammatory activity. Compounds 5d, 7g, 7f, 7e, 7c, 5b, 6a, 7b, and 7a showed excellent potency with GI50 ranging from 0.1 to 10.9 µM against the MCF-7 cell line. Compounds 7f, 7g, 5c, 5d, 5b, 7e, and 6a exhibited good anti-inflammatory activity. Encouraged by these results, all the compounds were also tested for their antioxidant potency. Compounds 6a, 6c, 7b, 7c, 7f, and 7g were found to be excellent scavengers of all four free radicals (DPPH, NO, SOR, and H2O2).

IF 2.4 3区 化学 Q2 CHEMISTRY, ORGANIC Pub Date : 2024-10-20 DOI: 10.1080/10406638.2023.2271648
The topological indices provide quantitative structural characteristics of drug molecules that can be utilized to predict or establish correlations with the biological activity, physicochemical properties, and toxicity of the molecules. Such studies play a crucial role in the initial stages of drug development by aiding in the identification and optimization of potential drug candidates and providing cost-effective techniques for experimental studies. Cancer, a multifaceted disease, can originate in any part of the body due to various factors, including genetic mutations, environmental toxins, and lifestyle choices. Blood cancer, encompassing malignancies affecting the blood, bone marrow, and lymphatic systems, is the focus of this research paper. The current study investigates a comprehensive set of drugs employed in blood cancer treatment, including clofarabine, mercaptopurine, olutasidenib, glasdegib, gliteritinib, zanubrutinib, chlorambucil, ibrutinib, bosutinib, hydroxyurea, cyclophosphamide, doxorubicin, daunorubicin, ivosidenib, prednisone, busulfan, omacetaxine mepesuccinate, and asciminib. By conducting a thorough analysis of these drugs, we acquire valuable insights into their molecular properties, which are crucial for predicting their behavior and efficacy in blood cancer treatment. We have devised QSPR models by leveraging the reverse degree and entropy topological indices. Our proposed QSPR models are compared with existing degree-based models, emphasizing the superior effectiveness of our approach.

Rate of Horizontal Spread of Fluorene in a Sandy Loam under Natural Environment 自然环境下芴在沙质壤土中的水平扩散速率
IF 2.4 3区 化学 Q2 CHEMISTRY, ORGANIC Pub Date : 2024-10-20 DOI: 10.1080/10406638.2023.2276240
Rate of horizontal movement of a pollutant such as polycyclic aromatic hydrocarbons in soil plays a major role in spread of pollutants in the segments of the environment. However, the study regarding this aspect is not widely reported. In the present work, the rate of horizontal spread of Fluorene in soil is determined in an experiment spread over a year under natural environment. Known amount of the hydrocarbon was added to a soil at a particular point, extraction of the same was done later on at definite time interval at definite distances from the point of application and quantitative determination was done by HPLC analysis of the extract. Eleven number of important physico-chemical parameters of the soil sample were determined/calculated in order to know the quality of the soil. The values of parameters are in agreement to the characteristics of a good soil. The experimental soil is a mild acidic sandy loam. It has been found that one-year time is sufficient for the applied quantity of the hydrocarbon to spread itself uniformly to attain a concentration, which is at par with natural concentration of the hydrocarbon in the experimental soil. Studies on kinetics of the reaction imply that the reaction occurs in different phases, rate constants being gradually increased with time. The positive influence of increase in ambient temperature and rainfall on disappearance of the hydrocarbon is seen in the experiment. It has been found that the most probable speed of the hydrocarbon for horizontal movement is 3.75 cm per month in the experimental soil.
污染物(如多环芳烃)在土壤中的水平移动速度对污染物在环境中的扩散起着重要作用。然而,有关这方面的研究报道并不多。本研究在自然环境下进行了为期一年的实验,测定了芴在土壤中的水平扩散速率。在特定位置向土壤中添加已知量的碳氢化合物,随后在距离添加点一定距离的特定时间间隔内提取相同的碳氢化合物,并通过高效液相色谱法对提取物进行定量测定。为了了解土壤的质量,对土壤样本的 11 个重要物理化学参数进行了测定/计算。参数值符合良好土壤的特征。实验土壤为弱酸性砂质壤土。研究发现,一年的时间足以让施用的碳氢化合物均匀扩散,达到与实验土壤中碳氢化合物天然浓度相当的浓度。对反应动力学的研究表明,反应发生在不同阶段,速率常数随时间逐渐增加。实验表明,环境温度和降雨量的增加对碳氢化合物的消失有积极影响。实验发现,在实验土壤中,碳氢化合物最有可能的水平移动速度是每月 3.75 厘米。

Literature shows that pyrimidine-derived compounds have very active biological properties. For this reason, the biologically active properties of the synthesized compound were also examined. To determine embryotoxic, genotoxic, and cytotoxic effects of compound, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT), lactate dehydrogenase (LDH) release, micronucleus (MN) and 8-OH-dG assays were carried out. On the other hand, pharmacokinetic and toxicity properties (ADMET) were predicted in silico via SwissADME and Protox-II web tools. In silico estimates of this compound used in the study showed that the compound has the covetable physicochemical properties for bioavailability. In conclusion, the obtained results of our study clearly showed that this compound exerted strong toxicity potential.

The 2,4,6-trifluoro-5-chloro pyrimidine (TF5CP) was chosen for extensive investigation of its theoretical and experimental vibrational assignments, structural benchmarks, and spectroscopic (FT-IR, FT-Raman, UV–Vis, and NMR) investigations by Hartree–Fock (HF) functional with 6-311 + G(2d,p) basis set. The spectrum of detailed vibrational interpretation was to be provided by the MOLVIB software. Bonding orbitals participate in all stages of natural bond orbitals (NBO) analysis as donors and acceptors, which stabilizes molecules through intermolecular charge transfer. Molecular docking research was used to foresee the binding interactions of the TF5CP derivative with the receptor 3WZD. Auto-dock software was used to a conduct receptor–ligand docking investigation. According to the molecular docking results, the highest mean negative binding affinity (–5.639 kcal/mol) was exhibited by the current chemical. Based on the five-point rule of Lipinski, drug similarity was determined, and the ADMET variables were also predicted.

IF 2.4 3区 化学 Q2 CHEMISTRY, ORGANIC Pub Date : 2024-10-20 DOI: 10.1080/10406638.2023.2273878
Ziziphus jujuba plant belongs to Rhamnaceous family and grows mainly in Europe, southern and eastern Asia, and Australia. Recent phytochemical investigation of plants provided some information on their biological effects, such as the hepatoprotective, immunostimulating, anti-obesity, anti-inflammatory, and anti-cancer properties. The current study investigated 34 phytocompounds from Z. jujuba and three anti-cancer drugs against three lung cancer target proteins. Drug likeliness screening revealed that two compounds dodecanoic acid and 7,9-di-tert-butyl-1-oxaspiro[4,5]deca-6,9-diene-2,8-dione possess zero violation, and compound azelaic acid possesses single violation against five drug rules. Molecular docking study reveals that 34 phytocompounds from Z. jujuba and three anti-cancer drugs showed docking score values in the range of −3.9 to −10.2 kcal/mol and −7.2 to −9.0 kcal/mol against three significant lung cancer target proteins. Furthermore, in silico screening top scored three phytocompounds campesterol, stigmast-5-en-3-ol, 7,9-di-tert-butyl-1-oxaspiro[4,5]deca-6,9-diene-2,8-dione and three anti-cancer drugs etoposide, paclitaxel, and doxorubicin utilized. Pharmacokinetic profile of three phytocompounds from Z. jujuba showed excellent absorption, distribution, metabolism, excretion, and toxicity profile than standard drugs. Furthermore, bioactivity and density functional theory analysis showed that phytocompounds from Z. jujuba possess better bioactivity scores and molecular electrostatic potentials than standard drugs. Molecular dynamics simulation results revealed that campesterol with CDK2 (PDB ID 1GII) and MDM2/P53 (4HFZ) target proteins possess better simulation trajectories and binding affinity than standard drugs. Further clinical trials of compounds (campesterol, stigmast-5-en-3-ol, 7,9-di-tert-butyl-1-oxaspiro[4,5]deca-6,9-diene-2,8-dione) are needed to check clinical pertinence toward lung cancer target proteins to commercialize these novel drug molecule in the drug industry.
酸枣属于鼠李科植物,主要生长在欧洲、亚洲南部和东部以及澳大利亚。最近对植物进行的植物化学调查提供了一些有关其生物效应的信息,如保护肝脏、免疫刺激、抗肥胖、抗炎和抗癌特性。目前的研究调查了 34 种来自竹叶青的植物化合物和三种针对三种肺癌靶蛋白的抗癌药物。药物相似性筛选结果表明,十二酸和 7,9- 二叔丁基-1-氧杂螺[4,5]癸-6,9-二烯-2,8-二酮这两种化合物对五种药物规则的违反率为零,壬二酸化合物对五种药物规则的违反率为零。分子对接研究显示,34 种植物化合物和 3 种抗癌药物针对 3 种重要的肺癌靶蛋白的对接分值范围分别为 -3.9 至 -10.2 kcal/mol 和 -7.2 至 -9.0 kcal/mol。此外,还对三种植物化合物坎贝斯特醇、柱头甾-5-烯-3-醇、7,9-二叔丁基-1-氧杂螺[4,5]癸-6,9-二烯-2,8-二酮和三种抗癌药物依托泊苷、紫杉醇和多柔比星进行了硅学筛选。三种植物化合物的药代动力学特征表明,它们的吸收、分布、代谢、排泄和毒性特征均优于标准药物。此外,生物活性和密度泛函理论分析表明,与标准药物相比,竹叶青的植物化合物具有更好的生物活性评分和分子静电位。分子动力学模拟结果表明,莰烯醇与 CDK2(PDB ID 1GII)和 MDM2/P53 (4HFZ)靶蛋白的模拟轨迹和结合亲和力均优于标准药物。我们需要对化合物(坎贝酯醇、石杉碱甲-5-烯-3-醇、7,9-二叔丁基-1-氧杂螺[4,5]癸-6,9-二烯-2,8-二酮)进行进一步的临床试验,以检验其与肺癌靶蛋白的临床相关性,从而将这些新型药物分子商业化。

Utilizing NMR (1H-NMR and 13C-NMR), FT-IR, UV-Visible, and quantum chemical approaches by using the DFT technique, experiments on 2-phenylthioanline were carried out. The B3LYP method and the 6-311++G(d,p) basis set were used to optimize the molecular structure and vibrational modes. The ideal binding parameters match up well with the experimental binding parameters. VEDA successfully finished the assignments concerning the distribution of potential energy. The GIAO method was used to calculate shifts in the 1H-NMR and 13C-NMR, and the outcomes were compared to experimental spectra. The TDDFT approach and the CPCM solvent model were used to examine electronic properties such as UV-Vis (in the gas phase, methanol, Acetone, and DCM), and the results were compared to experimental UV-Vis spectra. The HOMO/LUMO energy values provide sufficient proof of such. Molecular docking and dynamic simulations were carried out with a 2HI4 protein target and gave the best result among the three proteins.
