Abstract
Background: Diabetes mellitus is a serious global health concern, and this is expected to impact more than 300 million people by 2025. The current study focuses on identifying substituted indolin-2-one-based inhibitors for two indispensable drug targets, α-amylase and α-glucosidase. Methods: The structures of synthetic compounds were confirmed by spectroscopic techniques and evaluated for enzyme inhibition activities. Kinetic and in silico studies were also performed. Results: All compounds exhibited good-to-moderate inhibitory potential. Most importantly, compounds 1, 2, 6, 16 and 17 were identified as potent α-glucosidase inhibitors (IC50 = 9.15 ± 0.12-13.74 ± 0.12 μM). Conclusion: This study identified that these synthetic compounds might serve as potential lead molecules for antidiabetic agents.

Novel thiomorpholine tethered isatin hydrazones as potential inhibitors of resistant Mycobacterium tuberculosis. Bioorg Chem 2021; 115:105133.

Abstract
Novel chemotherapeutic agents against multidrug resistant-tuberculosis (MDR-TB) are urgently needed at this juncture to save the life of TB-infected patients. In this work, we have synthesized and characterized novel isatin hydrazones 4(a-o) and their thiomorpholine tethered analogues 5(a-o). All the synthesized compounds were initially screened for their anti-mycobacterial activity against the H37Rv strain of Mycobacterium tuberculosis (MTB) under level-I testing. Remarkably, five compounds 4f, 4h, 4n, 5f and 5m (IC50 = 1.9 µM to 9.8 µM) were found to be most active, with 4f (IC50 = 1.9 µM) indicating highest inhibition of H37Rv. These compounds were further evaluated at level-II testing against the five drug-resistant strains such as isoniazid-resistant strains (INH-R1 and INH-R2), rifampicin-resistant strains (RIF-R1 and RIF-R2) and fluoroquinolone-resistant strain (FQ-R1) of MTB. Interestingly, 4f and 5f emerged as the most potent compounds with IC50 of 3.6 µM and 1.9 µM against RIF-R1 MTB strain, followed by INH-R1 MTB strain with IC50 of 3.5 µM and 3.4 µM, respectively. Against FQ-R1 MTB strain, the lead compounds 4f and 5f displayed excellent inhibition at IC50 5.9 µM and 4.9 µM, respectively indicating broad-spectrum of activity. Further, molecular docking, ADME pharmacokinetic and molecular dynamics simulations of the compounds were performed against the DNA gyrase B and obtained encouraging results.

A Series of Isatin-Hydrazones with Cytotoxic Activity and CDK2 Kinase Inhibitory Activity: A Potential Type II ATP Competitive Inhibitor. Molecules 2020; 25:E4400.

Abstract
Isatin derivatives potentially act on various biological targets. In this article, a series of novel isatin-hydrazones were synthesized in excellent yields. Their cytotoxicity was tested against human breast adenocarcinoma (MCF7) and human ovary adenocarcinoma (A2780) cell lines using MTT assay. Compounds 4j (IC50 = 1.51 ± 0.09 µM) and 4k (IC50 = 3.56 ± 0.31) showed excellent activity against MCF7, whereas compound 4e showed considerable cytotoxicity against both tested cell lines, MCF7 (IC50 = 5.46 ± 0.71 µM) and A2780 (IC50 = 18.96± 2.52 µM), respectively. Structure-activity relationships (SARs) revealed that, halogen substituents at 2,6-position of the C-ring of isatin-hydrazones are the most potent derivatives. In-silico absorption, distribution, metabolism and excretion (ADME) results demonstrated recommended drug likeness properties. Compounds 4j (IC50 = 0.245 µM) and 4k (IC50 = 0.300 µM) exhibited good inhibitory activity against the cell cycle regulator CDK2 protein kinase compared to imatinib (IC50 = 0.131 µM). A molecular docking study of 4j and 4k confirmed both compounds as type II ATP competitive inhibitors that made interactions with ATP binding pocket residues, as well as lacking interactions with active state DFG motif residues.

Abstract
The synthesis and molecular characterization of new isatin-based hydrazonoindolin-2-ones 4a-o and 7a-e are reported. The in vitro anti-proliferative potential of the synthesized compounds 4a-o and 7a-e was examined against HT-29 (colon), ZR-75 (breast) and A549 (lung) human cancer cell lines. Compounds 7b, 7d and 7e were the most active congeners against the tested human cancer cell lines with average IC50 values of 4.77, 3.39 and 2.37 μM, respectively, as compared with the reference isatin-based drug, sunitinib, which exhibited an average IC50 value of 8.11 μM. Compound 7e was selected for further pharmacological evaluation in order to gain insight into its possible mechanism of action. It increased caspase 3/7 activity by 2.4- and 1.85-fold between 4 and 8 h of treatment, respectively, at 10 μM and it caused a decrease in the percentage of cells in the G1 phase of the cell cycle with a corresponding increase in the S-phase. In addition, compound 7e increased phosphorylated tyrosine (p-Tyr) levels nearly two-fold with an apparent IC50 value of 3.8 μM. The 7e-loaded PLGA microspheres were prepared using a modified emulsion-solvent diffusion method. The average encapsulation efficiency of the 7e-loaded PLGA microspheres was 85% ± 1.3. While, the in vitro release profile of the 7e-loaded microspheres was characterized by slow and continuous release of compound 7e during 21 days and the release curve was fitted to zero order kinetics. Incorporation of 7e into PLGA microspheres improved its in vitro anti-proliferative activity toward the human cancer cell line A549 after 120 h incubation period with an IC50 value less than 0.8 μM.

Abstract
The docking studies on CDK2 and GSK-3β inspired us to synthesis a series of indoline-2,3-dione hydrazones 10a-l. Treatment of indoline-2,3-dione derivatives 7a-d with hydrazine gave 3-hydrazonoindolin-2-ones 8a-d which were reacted with the appropriate aldehydes 9a-c to yield 3-substituted-(methylenehydrazono)indolin-2-ones 10a-l. Compounds 10a-l showed a significant anticancer activity against human breast cell line MCF-7. Compounds 10c, f, i exhibited the highest activity almost the same of doxorubicin (IC50 = 6.10 μM) with IC50 = 7.75, 6.75, 6.25 μM, respectively.
