Abstract: New thiosemicarbazones were synthesized in excellent yield reaction of indole derivatives with thiosemicarbazides. These thiosemicarbazones were reacted with ethyl bromoacetate to produce original heterocyclic-substituted indole derivatives possessing a 4-oxo-thiazolidine group. Analytical IR and NMR spectra and elemental analysis were performed to reveal their structures. The antimicrobial activity of all synthesized compounds was evaluated for antibacterial activity in vitro against Gram-positive and Gram-negative bacteria. Antibacterial screening data showed that two compounds demonstrated activity against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. These preliminary results indicate that some of these newly synthesized compounds show a promising antibacterial potency. Graphic abstract: [Figure not available: see fulltext.].

Using matrine (1) as the lead compound, a series of new 14-(N-substituted-2-pyrrolemethylene) matrine and 14-(N-substituted-indolemethylene) matrine derivatives was designed and synthesized for their potential application as anticancer agents. The structure of these compounds was characterized by 1H NMR, 13C NMR and ESI-MS spectral analyses. The target compounds were evaluated for their in vitro cytotoxicity against three human cancer cell lines (SMMC-7721, A549 and CNE2). The results revealed that compound A6 and B21 displayed the most significant anticancer activity against three cancer cell lines with IC50 values in range of 3.42–8.05 μM, which showed better activity than the parent compound (Matrine) and positive control Cisplatin. Furthermore, the Annexin V-FITC/PI dual staining assay revealed that compound A6 and B21 could significantly induce the apoptosis of SMMC-7721 and CNE2 cells in a dose-dependent manner. The cell cycle analysis also revealed that compound A6 could cause cell cycle arrest of SMMC-7721 and CNE2 cells at G2/M phase.

Clinical studies have revealed that diabetic retinopathy is a multifactorial disorder. Moreover, studies also suggest that ALR2 and PARP-1 co-occur in retinal cells, making them appropriate targets for the treatment of diabetic retinopathy. To find the dual inhibitors of ALR2 and PARP-1, the structure based design was carried out in parallel for both the target proteins. A series of novel thiazolidine-2,4-dione (TZD) derivatives were therefore rationally designed, synthesized and their in vitro inhibitory activities against ALR2 and PARP-1 were evaluated. The experimental results showed that compounds 5b and 5f, with 2-chloro and 4-fluoro substitutions, showed biochemical activities in micromolar and submicromolar range (IC50 1.34–5.03?μM) against both the targeted enzymes. The structure-activity relationship elucidated for these novel inhibitors against both the enzymes provide new insight into the binding mode of the inhibitors to the active sites of enzymes. The positive results of the biochemical assay suggest that these compounds may be further optimized and utilized for the treatment of diabetic retinopathy.

Poly (ADP-ribose) polymerase (PARP-1) is a well-established nuclear protein with prominent role in signaling and DNA repair. Various clinical candidates have been identified with the role in PARP-1 inhibition. Based on the pharmacophoric features identified from previous studies and molecular docking interactions, thiazolidine-2,4-dione derivatives have been evaluated for their PARP inhibitory activity. From an in vitro assay, 5-((1-(4-isopropylbenzyl)-1H-indol-3-yl)methylene)thiazolidine-2,4-dione (16) was identified as a potent inhibitor having low micromolar inhibitory activity (IC50=0.74±0.25μM). Thus, a structure-based design approach utilized in the present study helped to identify thiazolidine-2,4-dione as a novel scaffold against PARP-1 for potential development of potent anticancer therapeutics.

A new series of pyrano chalcone derivatives containing indole moiety (3-42, 49a-49r) were synthesized and evaluated for their antiproliferative activities. Among all the compounds, compound 49b with a propionyloxy group at the 4-position of the left phenyl ring and N-methyl-5-indoly on the right ring displayed the most potent cytotoxic activity against all tested cancer cell lines including multidrug resistant phenotype, which inhibits cancer cell growth with IC50 values ranging from 0.22 to 1.80 μM. Furthermore, 49b significantly induced cell cycle arrest in G2/M phase and inhibited the polymerization of tubulin. Molecular docking analysis demonstrated the interaction of 49b at the colchicine binding site of tubulin. In experiments in vivo, 49b exerted potent anticancer activity in HepG2 human liver carcinoma in BALB/c nude mice. These results indicated these compounds are promising inhibitors of tubulin polymerization for the potential treatment of cancer.

A series of 2-hydrazinyl-4-morpholinothieno[3,2-d]pyrimidine derivatives were synthesized and evaluated for their cytotoxic activities against five cancer cell lines. Most of them exhibited moderate to significant cytotoxic activities and high-selectivity against one or more cell lines, and nearly all of them had higher potency than positive controls against MDA-MB-231 cell line. The most promising compound 15f showed strong cytotoxic activities against H460, HT-29 and MDA-MB-231 cell lines, which were 1.7- to 66.5-folds more active than 2-(1H-Indazol-4-yl)-6-((4-(methylsulfonyl)-1-piperazinyl)methyl)-4-(4- morpholinyl)thieno[3,2-d]pyrimidine(GDC-0941). To investigate the SARs of thieno[3,2-d]pyrimidine derivatives in more details, CoMFA (q2 = 0.436, r2 = 0.937) and CoMSIA (q2 = 0.706, r2 = 0.947) models on H460 cell line were established. The generated 3D-QSAR models can be used for further rational design of novel thienopyrimidines as highly potent and selective cytotoxic agents.

A series of 6-hydrazinyl-2,4-bismorpholino pyrimidine and 1,3,5-triazine derivatives (5a-5l and 8a-8o) were synthesized and their chemical structures as well as the relative stereochemistry were confirmed. All the synthesized compounds were evaluated for antiproliferative activity against three cancer cell lines (H460, HT-29, and MDA-MB-231). Several potent compounds were further evaluated against two other cell lines (U87MG, H1975). Most of the prepared compounds, particularly compounds 5c and 5j with IC50 values (0.07 and 0.05 μM, respectively) in the nM range, exhibited moderate to excellent antiproliferative activity and high selectivity against the H460 cancer cell line as compared with compound 1. The most promising compound 5j, possessing a cyano group at the 3-position of the benzene ring, showed strong antiproliferative activity against H460, HT-29, and MDA-MB-231 cell lines with IC50 values of 0.05, 6.31, and 6.50 μM, which were 4.6- to 190.4-fold more active than compound 1 (9.52, 29.24, and 36.21 μM), respectively.
