| 1 | Model-Based Integrated Methods for Quantitative Estimation of Soil Salinity from Hyperspectral Remote Sensing Data:A Case Study of Selected South African Soils显示文摘Soil salinization is a land degradation process that leads to reduced agricultural yields. This study investigated the method that can best predict electrical conductivity (EC) in dry soils using individual bands, a normalized difference salinity index (NDSI), partial least squares regression (PLSR), and bagging PLSR. Soil spectral reflectance of dried, ground, and sieved soil samples containing varying amounts of EC was measured using an ASD FieldSpec spectrometer in a darkroom. Predictive models were computed using a training dataset. An independent validation dataset was used to validate the models. The results showed that good predictions could be made based on bagging PLSR using first derivative reflectance (validation R2 = 0.85), PLSR using untransformed reflectance (validation R2 = 0.70), NDSI (validation R2 = 0.65), and the untransformed individual band at 2257 nm (validation R2 = 0.60) predictive models. These suggested the potential of mapping soil salinity using airborne and/or satellite hyperspectral data during dry seasons. | Z. E. MASHIMBYE M. A. CHO J. P. NELL W. P. DE CLERCQ A. VAN NIEKERK D.

| 4 | Approved HIV reverse transcriptase inhibitors in the past decade显示文摘HIV reverse transcriptase(RT)inhibitors are the important components of highly active antiretroviral therapies(HAARTs)for anti-HIV treatment and pre-exposure prophylaxis in clinical practice.Many RT inhibitors and their combination regimens have been approved in the past ten years,but a review on their drug discovery,pharmacology,and clinical efficacy is lacking.Here,we provide a comprehensive review of RT inhibitors(tenofovir alafenamide,rilpivirine,doravirine,dapivirine,azvudine and elsulfavirine)approved in the past decade,regarding their drug discovery,pharmacology,and clinical efficacy in randomized controlled trials.Novel RT inhibitors such as islatravir,MK-8504,MK-8507,MK8583,IQP-0528,and MIV-150 will be also highlighted.Future development may focus on the new generation of novel antiretroviral inhibitors with higher bioavailability,longer elimination half-life,more favorable side-effect profiles,fewer drug–drug interactions,and higher activities against circulating drug-resistant strains. | Guangdi Li Yali Wang Erik De Clercq | 2022 | Acta Pharmaceutica Sinica B2022,12,4: | 5 |
| 5 | Interactive Study between Two Types of 1-[2-(Hydroxyethoxy)methyl] -6-naphthylmethylthymines and HIV-1 Reverse Transcriptase显示文摘Two different types of 1-[2-(hydroxyethoxy)methyl]-6-naphthylmethylthymines have been designed, synthesized and evaluated for their anti-HIV-1 activities in different cells lines. The binding free energy (DG) including steric and electrostatic between the two different ligands and reverse transcriptase Non-Nucleoside Binding Pocket (NNBP) have been docked and calculated to evaluate their accommodation circumstance on a SGI work station. The DG and anti-HIV-1 activity has been correlated in order to guide further drug design, which showed that the steric binding effect dominated in the whole binding action between the compounds and reverse transcriptase (RT). The results showed that more negative DG led to higher activity of compounds. | 孟歌 陈芬儿 De Clercq Erik 戴惠芳 | 2003 | 过程工程学报2003,3,1: | 4 |

| 7 | S-DAPYs类似物的分子设计、合成及抑制HIV-1的活性研究显示文摘我们以已上市的etravirine和正在临床研究的VRX-480773两个逆转录酶抑制剂为模板,通过杂交这两个化合物的药效团,获得含酰胺片段的S—DAPYs类似物,该类似物对野生型HIV-1病毒株具有中等强度抑制活性.而Maurizio所发现的另一类无酰胺片段的S.DAPYs类似物却表现出优异的抑制活性.为了考察酰胺片段对S-DAPYs类似物抑制HIV-1活性的影响,本文合成了一系列无酰胺片段的S—DAPYs类似物.生物活性结果表明,3个化合物(6g、6m和6s)对野生型HIV-1具有中等强度抑制活性(EC50在6.5~15.4μmol/L范围内),弱于相应的具有酰胺片段的类似物.此外,分子模拟还揭示了酰胺片段可与K103形成至关重要的氢键作用,这为新型非核苷类逆转录酶抑制剂的设计奠定了理论基础. | 万正勇 陈芬儿 Erik De Clercq Dirk Daelemans Christophe Pannecouque | 2015 | 中国科学:化学2015,45,9: | 2 |

| 19 | Development of fluorine-substituted NH_(2)-biphenyl-diarylpyrimidines as highly potent non-nucleoside reverse transcriptase inhibitors:Boosting the safety and metabolic stability显示文摘Our recent studies for nonnucleoside reverse transcriptase inhibitors identified a highly potent compound JK-4b against WT HIV-1(EC_(50)=1.0 nmol/L),but the poor metabolic stability in human liver microsomes(t_(1/2)=14.6 min)and insufficient selectivity(SI=2059)with high cytotoxicity(CC_(50)=2.08μmol/L)remained major issues associated with JK-4b.The present efforts were devoted to the introduction of fluorine into the biphenyl ring of JK-4b,leading to the discovery of a novel series of fluorine-substituted NH_(2)-biphenyl-diarylpyrimidines with noticeable inhibitory activity toward WT HIV-1 strain(EC_(50)=1.8–349 nmol/L).The best compound 5t in this collection(EC_(50)=1.8 nmol/L,CC_(50)=117μmol/L)was 32-fold in selectivity(SI=66,443)compared to JK-4b and showed remarkable potency toward clinically multiple mutant strains,such as L100I,K103N,E138K,and Y181C.The metabolic stability of 5t was also significantly improved(t_(1/2)=74.52 min),approximately 5-fold higher than JK-4b in human liver microsomes(t_(1/2)=14.6 min).Also,5t possessed good stability in both human and monkey plasma.No significant in vitro inhibition effect toward CYP enzyme and hERG was observed.The single-dose acute toxicity test did not induce mice death or obvious pathological damage.These findings pave the way for further development of 5t as a drug candidate. | Xin Jin Shuai Wang Limin Zhao Wenjuan Huang Yinxiang Zhang Christophe Pannecouque Erik De Clercq Ge Meng Huri Piao Fener Chen | 2023 | Acta Pharmaceutica Sinica B2023,13,3: | 1 |
