Tri, Nguyen Minh,Thanh, Nguyen Dinh,Ha, Luong Ngoc,Anh, Dang Thi Tuyet,Toan, Vu Ngoc,Giang, Nguyen Thi Kim

, p. 4793 - 4801 (2021/05/31)

Substituted N-propargyl isatins were synthesized by SN2 reaction of corresponding substituted isatins with propargyl bromide in the presence of anhydrous K2CO3 as base. We reported about study on systematically synthesis of these compounds using heating procedures under different reaction conditions, including microwave-assisted heating conditions at power of 100?W (Procedure A), conventional heating conditions in water bath at 50?°C in acetonitrile (Procedure B), and conventional heating conditions in water bath at 50?°C in DMF (procedure C). The best procedure A was deduced based on the investigations on the reaction conditions. Almost all substituted N-propargyl isatins were new, except compounds with R of H, 5-Me, 5-Cl and 5-Br substituents. The structures of the obtained compounds were confirmed by the modern spectroscopic methods.

The inadequate clinical efficacy of the present anti-Alzheimer's disease (AD) drugs and their low impact on the progression of Alzheimer's disease in patients have revised the research focus from single targets to multitarget-directed ligands. A novel series of substituted triazinoindole derivatives were obtained by introducing various substituents on the indole ring for the development of multitarget-directed ligands as anti-AD agents. The experimental data indicated that some of these compounds exhibited significant anti-AD properties. Among them, 8-(piperidin-1-yl)-N-(6-(pyrrolidin-1-yl)hexyl)-5H-[1,2,4]triazino[5,6-b]indol-3-amine (60), the most potent cholinesterase inhibitor (AChE, IC50 value of 0.32 μM; BuChE, IC50 value of 0.21 μM), was also found to possess significant self-mediated Aβ1-42 aggregation inhibitory activity (54% at 25 μM concentration). Additionally, compound 60 showed strong antioxidant activity. In the PAMPA assay, compound 60 exhibited blood-brain barrier penetrating ability. An acute toxicity study in rats demonstrated no sign of toxicity at doses up to 2000 mg/kg. Furthermore, compound 60 significantly restored the cognitive deficits in the scopolamine-induced mice model and Aβ1-42-induced rat model. In the in silico ADMET prediction studies, the compound satisfied all the parameters of CNS acting drugs. These results highlighted the potential of compound 60 to be a promising multitarget-directed ligand for the development of potential anti-AD drugs.

Chen, Huan,Hou, Baolong,Liu, Jianli,Liu, Li,Ma, Xiumei,Wang, Cuiling,Wang, Jilin,Wang, Rui,Wang, Yinyin,Zheng, Xudong

, (2019/11/13)

The natural alkaloid, tryptanthrin (indolo[2,1-b]quinazoline-6,12-dione), and its analogues are found to exhibit potent antitumor and anti-MRSA activities. An efficient and convenient method has been developed for the synthesis of tryptanthrin D-ring derivatives through the reaction of substituted tryptanthrins and secondary amines in moderate to good yields. Some of the new compounds exhibited antitumor activities against the human tumor cell lines A549, HCT116 and MDA-MB-231, with mean IC50 values at low micromolar levels. In addition, some of the compounds showed excellent anti-MRSA activities and were more effective than vancomycin, with MIC values of 0.31–1.25 μg/mL for Mu50,RN4220, and Newman strains.

Microtubule affinity-regulating kinase 4 (MARK4) is a potential drug target as the same is found to be over expressed in several types of cancers. In search of effective MARK4 inhibitors, we have synthesized and characterized Isatin-triazole hydrazones (9a-i) and evaluated their inhibitory potential. Of all the compounds, 9g showed better binding affinity and enzyme inhibition potential in sub micromolar range. Human serum albumin (HSA) binding assay suggested an easy transportation of 9g in blood stream due to its binding affinity. In vitro anticancer studies performed on MCF-7, MDA-MB-435s and HepG2 cells using 9g showed inhibition of cell proliferation and cell migration. Further, 9g induces apoptosis in these cancerous cells, with IC50 values of 6.22, 9.94 and 8.14 μM, respectively. Putatively, 9g seems to cause oxidative stress resulting in apoptosis. Functional assay of 9g with a panel of 26 kinases showed MARK4 specific profile. In conclusion, 9g seems to possess an effective inhibitory potential towards MARK4 adding an additional repertoire to anticancer therapeutics.

A number of 5-arylisatin derivatives were synthesized in 5–6 steps from readily available starting materials. Their structures were confirmed by 1H NMR and 13C NMR as well as LC/MS. The cytotoxicity of these novel isatins against human leukemia K562 cells were evaluated by MTT assay in vitro. SAR studies indicated that the N-substituted benzyl and C-5 substituted phenyl groups greatly enhance their cytotoxic activity, whereas an intact carbonyl functionality on C-3 present in the parent ring is required to maintain such a potency. Particularly, N-(p-methoxybenzyl)-5-(p-methoxyphenyl)isatin (compound 2m) showed the highest antitumor activity against K562 cell lines (IC50 = 0.03 μM). Moreover, treatment with compound 2m significantly inhibited liver cancer HepG2 cells proliferation and migration, which could also reduce the human umbilical vein endothelial cells (HUVEC) tube formation. In conclusion, compound 2m exhibited very good cancer cells proliferation inhibition by angiogenesis responses in vitro, and 2m might be a promising angiogenesis inhibitor for cancer treatment.

The study represents the new findings at the crossroads of chemistry and medicine, particularly between medicinal and organic chemistry and ophthalmology. In this work we describe how the chemical reactivity of indolinone scaffold may be used to create small molecule ligands with strong biological response comparable with and larger than that of endogenous hormone. The synthesis of oxindole-based melatonin and 5-methoxycarbonylamino-N-acetyltryptamine (5-MCA-NAT) analogues was proposed and their ability to influence intraocular pressure (IOP) was studied in vivo. Time-dependent study revealed the prolonged effect (more than 6?h) of the lead-compound. This effect in combination with high IOP reducing effect (41?±?6%) in low concentrations of the active compound (0.1?wt%) and with high water solubility represents a great potential of low-cost oxindole derivatives as potent antiglaucoma agents.

Natural α-methylenelactam analogues: Design, synthesis and evaluation of α-alkenyl-γ and δ-lactams as potential antifungal agents against Colletotrichum orbiculare

Delong, Wang,Lanying, Wang,Yongling, Wu,Shuang, Song,Juntao, Feng,Xing, Zhang

, p. 286 - 307 (2017/03/09)

In our continued efforts to improve the potential utility of the α-methylene-γ-lactone scaffold, 62 new and 59 known natural α-methylenelactam analogues including α-methylene-γ-lactams, α-arylidene-γ and δ-lactams, and 3-arylideneindolin-2-ones were synthesized as the bioisosteric analogues of the α-methylenelactone scaffold. The results of antifungal and cytotoxic activity indicated that among these derivatives compound (E)-1-(2, 6-dichlorobenzyl)-3-(2-fluorobenzylidene) pyrrolidin-2-one (Py51) possessed good selectivity with the highest antifungal activity against Colletotrichum orbiculare with IC50?=?10.4?μM but less cytotoxic activity with IC50?=?141.2?μM (against HepG2 cell line) and 161.2?μM (against human hepatic L02?cell line). Ultrastructural change studies performed by transmission electron microscope showed that Py51 could cause important cell morphological changes in C.?orbiculare, such as plasma membrane detached from cell wall, cell wall thickening, mitochondria disruption, a dramatic increase in vacuolation, and eventually a complete loss in the integrity of organelles. Significantly, mitochondria appeared one of the primary targets, as confirmed by their remarkably aberrant morphological changes. Analysis of structure–activity relationships revealed that incorporation of the aryl group into the α-exo-methylene and the N-benzyl substitution increased the activity. Meanwhile, the α-arylidene-γ-lactams have superiority in selectivity over the 3-arylideneindolin-2-ones. Based on the results, the N-benzyl substituted α-(2-fluorophenyl)-γ-lactam was identified as the most promising natural-based scaffold for further discovering and developing improved crop-protection agents.

Design, synthesis and biological evaluation of dual acetylcholinesterase and phosphodiesterase 5A inhibitors in treatment for Alzheimer's disease

Zhou, Li-yun,Zhu, Yao,Jiang, Yu-ren,Zhao, Xiong-jie,Guo, Dong

, p. 4180 - 4184 (2017/08/23)

With the recent research advances in molecular biology and technology, multiple credible hypotheses about the progress of Alzheimer's disease (AD) have been proposed; multi-target drugs have emerged as an innovative therapeutic approach for AD. Current clinical therapy for AD patients is mainly palliative treatment targeting acetylcholinesterase (AChE). Inhibition of phosphodiesterase 5A (PDE5A) has recently been validated as a potentially novel therapeutic approach for Alzheimer's disease (AD). In this work, series of new compounds were designed, synthesized and evaluated as dual cholinesterase and PDE5A inhibitor. Biological results revealed that some of these compounds display good biological activities against AChE with IC50 values about 44.67–169.80 nM (donepezil IC50 50.12 nM). Notably, compound 12 presented potent activities against PDE5A with IC50 values about 50 μM (sildenafil IC50 12.59 μM), and some of these compounds showed low cell toxicity to A549 cells in vitro.

Methylisoindigo and its bromo-derivatives are selective tyrosine kinase inhibitors, repressing cellular stat3 activity, and target CD133+ cancer stem cells in PDAC

Indirubin is an active component of the herbal ingredient 'Danggui Longhui wan', which was used for the treatment of inflammation and chronic myeloid leukemia in China. The recent study showed its derivative methylisoindigo (also known as meisoindigo) preferentially targeting cancer stem cells (CSCs) in interference with AMPK and LKB1, the cellular metabolic sensors. In this study, we screened the effect of meisoindigo on a panel of 300 protein kinases and found that it selectively inhibited Stat3-associated tyrosine kinases and further confirmed its activity in cell based assays. To gain a deeper insight into the structure-activity relationship we produced 7 bromo-derivatives exhausting the accessible positions on the bisindole backbone except for in the 4-position due to the space limitation. We compared their anti-proliferative effects on tumor cells. We found that 6-bromomeisoindigo showed improved toxicity in company with increased Stat3 inhibition. Moreover, we detected that 6-bromomeisoindigo induced apoptosis of 95% of CD133+ pancreatic cancer cells. Considering that CD133 is a common marker highly expressed in a range of CSCs, our results imply the potential application of 6-bromomeisoindigo for the treatment of CSCs in different types of cancers.
