Based on the hybridization of the privileged fragments in DABO and DAPY‐typed HIV‐1 NNRTIs, a novel series of 4‐aminopiperidinyl‐linked 3,5‐disubstituted‐1,2,6‐thiadiazine‐1,1‐dione derivatives were designed, synthesized, and evaluated for their in vitro anti‐HIV activities in MT‐4 cells. Most of the target compounds showed weak inhibitory activity against WT HIV‐1. In order to confirm the mode of action of the target compounds, representative compounds Ba8 and Bb8 were selected to perform the HIV‐1 RT inhibitory assay. In this assay, Ba8 and Bb8 displayed good activity with IC50 values of 3.15 and 1.52 μm , respectively. Additionally, preliminary structure–activity relationships (SARs) analysis and molecular docking studies of newly synthesized compounds are also discussed. 相似文献

A novel series of 1‐(thiophen‐2‐yl)‐9H‐pyrido [3,4‐b]indole derivatives were synthesized using DL‐tryptophan as starting material. All the compounds were characterized by spectral analysis such as 1H NMR, Mass, IR, elemental analysis and evaluated for inhibitory potency against HIV‐1 replication. Among the reported analogues, compound 7g exhibited significant anti‐HIV activity with EC50 0.53 μm and selectivity index 483; compounds 7e , 7i , and 7o displayed moderate activity with EC50 3.8, 3.8, and 2.8 μm and selectivity index >105, >105, and 3.85, respectively. Interestingly, compound 7g inhibited p24 antigen expression in acute HIV‐1IIIB infected cell line C8166 with EC50 1.1 μm . In this study, we also reported the Lipinski rule of 5 parameters, predicted toxicity profile, drug‐likeness, and drug score of the synthesized analogues. 相似文献

A series of novel S‐DABO derivatives with the substituted 1,2,3‐triazole moiety on the C‐2 side chain were synthesized using the simple and efficient CuAAC reaction, and biologically evaluated as inhibitors of HIV‐1. Among them, the most active HIV‐1 inhibitor was compound 4‐((4‐((4‐(2,6‐dichlorobenzyl)‐5‐methyl‐6‐oxo‐1,6‐dihydropyrimidin‐2‐ylthio)methyl)‐1H‐1,2,3‐triazol‐1‐yl)methyl)benzenesulfonamide ( B5b7) , which exhibited similar HIV‐1 inhibitory potency (EC50 = 3.22 μm ) compared with 3TC (EC50 = 2.24 μm ). None of these compounds demonstrated inhibition against HIV‐2 replication. The preliminary structure–activity relationship (SAR) of these new derivatives was discussed briefly. 相似文献

4‐amino‐6‐alkyloxy‐2‐alkylthiopyrimidine derivatives as novel non‐nucleoside agonists for the adenosine A1 receptor 下载免费PDF全文

Three 4‐amino‐6‐alkyloxy‐2‐alkylthiopyrimidine derivatives ( 4 – 6 ) were investigated as potential non‐nucleoside agonists at human adenosine receptors (ARs). When tested in competition binding experiments, these compounds exhibited low micromolar affinity (Ki values comprised between 1.2 and 1.9 μm ) for the A1 AR and no appreciable affinity for the A2A and A3 ARs. Evaluation of their efficacy profiles by measurement of intracellular cAMP levels revealed that 4 and 5 behave as non‐nucleoside agonists of the A1 AR with EC50 values of 0.47 and 0.87 μm , respectively. No clear concentration‐response curves could be instead obtained for 6 , probably because this compound modulates one or more additional targets, thus masking the putative effects exerted by its activation of A1 AR. The three compounds were not able to modulate A2B AR‐mediated cAMP accumulation induced by the non‐selective AR agonist NECA, thus demonstrating no affinity toward this receptor. 相似文献

A series of sulfone derivatives containing 1, 3, 4‐oxadiazole moiety were prepared and evaluated for their antibacterial activities by the turbidimeter test. Most compounds inhibited growth of Ralstonia solanacearum (R. solanacearum) from tomato and tobacco bacterial wilt with high potency, among which compounds 5a and 5b exhibited the most potent inhibition against R. solanacearum from tomato and tobacco bacterial wilts with EC50 values of 19.77 and 8.29 μg/mL, respectively. Our results also demonstrated that 5a, 5b , and a number of other compounds were more potent than commercial bactericides Kocide 3000 and Thiodiazole Copper, which inhibited R. solanacearum from tomato bacterial wilt with EC50 values of 93.59 and 99.80 μg/mL and tobacco bacterial wilt with EC50 values of 45.91 and 216.70 μg/mL, respectively. The structure–activity relationship (SAR) of compounds was studied using three‐dimensional quantitative structure–activity relationship (3D‐QSAR) models created by comparative molecular field analysis (CoMFA) and comparative molecular similarity index analysis (CoMSIA) based on compound bioactivities against tomato and tobacco bacterial wilts. The 3D‐QSAR models effectively predicted the correlation between inhibitory activity and steric–electrostatic properties of compounds. 相似文献

In accordance with our antiviral drug development attempt, acylhydrazone derivatives bearing amino acid side chains were synthesized for the evaluation of their antiviral activity against various types of viruses. Among these compounds, 8 S , 11 S , and 12 S showed anti‐HIV‐1 activity with a 50% inhibitory concentration (IC50) = 123.8 µM (selectivity index, SI > 3), IC50 = 12.1 µM (SI > 29), IC50 = 17.4 µM (SI > 19), respectively. Enantiomers 8 R , 11 R , and 12 R were inactive against the HIV‐1 strain IIIB. Hydrazones 8 S , 11 S , and 12 S which were active against HIV‐1 wild type showed no inhibition against a double mutant NNRTI‐resistant strain (K103N;Y181C). Molecular docking calculations of R‐ and S‐enantiomers of 8 , 11 , and 12 were performed using the hydrazone‐bound novel site of HIV‐1 RT. 相似文献

A series of 2‐(substituted benzylamino)‐4‐methylthiazole‐5‐carboxylic acid was designed and synthesized as structural analogue of febuxostat. A methylene amine spacer was incorporated between the phenyl ring and thiazole ring in contrast to febuxostat in which the phenyl ring was directly linked with the thiazole moiety. The purpose of incorporating methylene amine was to provide a heteroatom which is expected to favour hydrogen bonding within the active site residues of the enzyme xanthine oxidase. The structure of all the compounds was established by the combined use of FT‐IR, NMR and MS spectral data. All the compounds were screened in vitro for their ability to inhibit the enzyme xanthine oxidase as per the reported procedure along with DPPH free radical scavenging assay. Compounds 5j, 5k and 5l demonstrated satisfactory potent xanthine oxidase inhibitory activities with IC50 values, 3.6, 8.1 and 9.9 μm , respectively, whereas compounds 5k , 5n and 5p demonstrated moderate antioxidant activities having IC50 15.3, 17.6 and 19.6 μm , respectively, along with xanthine oxidase inhibitory activity. Compound 5k showed moderate xanthine oxidase inhibitory activity as compared with febuxostat along with antioxidant activity. All the compounds were also studied for their binding affinity in active site of enzyme (PDB ID‐1N5X). 相似文献

In this study, novel acridone‐1,2,4‐oxadiazole‐1,2,3‐triazole hybrids were designed, synthesized, and evaluated for their acetylcholinesterase and butyrylcholinesterase inhibitory activity. Among various synthesized compounds, 10‐((1‐((3‐(4‐methoxyphenyl)‐1,2,4‐oxadiazol‐5‐yl)methyl)‐1H‐1,2,3‐triazol‐4‐yl)methyl)acridin‐9(10H)‐one 10b showed the most potent anti‐acetylcholinesterase activity (IC50 = 11.55 μm ) being as potent as rivastigmine. Also docking outcomes were in good agreement with in vitro results confirming the dual binding inhibitory activity of compound 10b . 相似文献

A series of 2‐amino‐aryl‐7‐aryl‐benzoxazole derivatives have been designed, synthesized, and evaluated as anticancer agents. Fourteen of the compounds exhibited cytotoxic effects toward human A549 lung cancer cells. We found 12l was the most potent with an EC50 of 0.4 μm , equivalent to the anticancer drug doxorubicin, but had low selectivity following cross screening in monkey kidney Vero cells. Eight of the most potent or most selective compounds were further profiled in additional cell lines (MCF7, NCI‐H187, and KB) to better understand their cytotoxic activity. Only compound 12l had a measurable EC50 in a single cell line (3.3 μm in the KB cell line). Taken together, this data suggest the series as a whole display specific cytotoxicity toward A549 cells. Cheminformatics searches pointed to JAK2 as a possible target. A subset of compounds assayed at this target showed IC50s ranging from 10 to 0.08 μm ; however, no clear correlation between JAK2 potency and A549 cytotoxicity was observed. 相似文献

A series of (E,Z)‐1‐(dihydrobenzofuran‐5‐yl)‐3‐phenyl‐2‐(1,2,4‐triazol‐1‐yl)‐2‐propen‐1‐ones ( C1 – C35 ) were designed and synthesized, and the structures of compounds (Z)‐ C27 and (Z)‐ C29 were confirmed by single‐crystal X‐ray diffraction. The antitumor activities of these novel compounds against cervical cancer (HeLa), lung cancer (A549), and breast cancer (MCF‐7) cell lines were evaluated in vitro. Majority of the title compounds exhibited strong antitumor activities and were much more promising than the positive control Taxol, which were also accompanied by lower cytotoxicity to normal cells. In particular, compounds (E,Z)‐ C24 exhibited the most consistent potent activities against three neoplastic cells with IC50 values ranging from 3.2 to 7.1 μm . Further researches demonstrated that compounds (E,Z)‐ C24 could induce cell apoptosis and arrest cell cycle at the G2/M and S phases. Meanwhile, the structure–activity relationship between the configurations and cytotoxicity of the compounds was also investigated. 相似文献
