ABSTRACT. We are reporting a novel series of thiosemicarbazone derivatives derived from isatin (1-6), structural determination, and investigation of the inhibitory properties against proliferative, carbonic anhydrase, and cholinesterase enzymes. The anti-proliferative effects of the compounds were measured by XTT assay against MCF-7 and MDA-MB-231 cancerous cell lines. Compound 3 showed significant cytotoxic effects on both MCF-7 and MDA-MB-231 cell lines, with IC50 values of 8.19 μM and 23.41 μM, respectively. In addition, the compounds (1-6) inhibited the hCA I and II, their Ki values 2.01 ± 0.35 – 21.55 ± 2.56 and 1.24 ± 0.33 – 25.03 ± 5.48 µM, respectively. AChE was also successfully inhibited by these compounds (1-6), with Ki values ranging from 40.37 ± 8.23 to 125.43 ± 24.93 µM. The best Ki values for 3, 6, and 4 for α-glycosidase were 564.35 ± 72.06, 594.38 ± 52.04, and 683.437 ± 66.58 µM, respectively. Binding affinities were determined to be -6.697 kcal/mol, -8.251 kcal/mol, -9.932 kcal/mol, and -4.946 kcal/mol for hCA I, hCA II, AChE, and α-glucosidase enzymes, respectively. These findings reveal that the formed compounds containing isatin moieties were crucial in the enzyme inhibition.

“…In Figure 7B at t = 0 h, the coloration that appears as blue corresponds to low absorbance values. However, it is important to consider the potential impact of DMSO interference, which arises from the absorption of DMSO within the spectral range of 289-303 nm [75]. At t = 3 h in Figure 8B, detection of GF was not possible at 280 nm.…”

The development of effective drug delivery systems remains a focus of extensive research to enhance therapeutic outcomes. Among these, in situ forming gels (ISG) have emerged as a promising avenue for controlled drug release. This research focuses on the mathematical modeling of levofloxacin HCl (Lv) release from zein-based ISG using the cup method, aiming to mimic the environment of a periodontal pocket. The drug release behavior of the ISGs was investigated through experimental observations and numerical simulations employing forward and central difference formula. Notably, the experimental data for drug release from the 20% w/w zein-based ISG formulations closely aligned with the simulations obtained from numerical mechanistic modeling. In summary, 20% w/w zein-based ISG formulations demonstrated nearly complete drug release with the maximum drug concentration at the edge of the matrix phase values consistently around 100–105%, while 25% w/w zein-based ISG formulations exhibited somewhat lower drug release extents, with values ranging from 70–90%. Additionally, the rate of drug transport from the polymer matrix to the external phase influenced initial release rates, resulting in a slower release. The utilization of glycerol formal as a solvent extended drug release further than dimethyl sulfoxide, thanks to denser matrices formed by high-loading polymers that acted as robust barriers to solvent removal and drug diffusion. Furthermore, UV-vis imaging was utilized to visualize the matrix formation process and solvent diffusion within the ISGs. The imaging results offered valuable insights into the matrix formation kinetics, controlled drug release mechanisms, and the influence of solvent properties on drug diffusion. The combination of mathematical modeling and experimental visualization provides a comprehensive understanding of drug release from zein-based ISGs and offers a foundation for tailored drug delivery strategies.

Eleven new thiosemicarbazone derivatives (1‐11) were designed from nine different biologically and pharmacologically important isothiocyanate derivatives containing functional groups such as fluorine, chlorine, methoxy, methyl, and nitro at various positions of the phenyl ring, in addition to the benzyl unit in the molecular skeletal structure. First, their substituted‐thiosemicarbazide derivatives were synthesized from the treatment of isothiocyanate with hydrazine to synthesize the designed compounds. Through a one‐step easy synthesis and an eco‐friendly process, the designed compounds were synthesized with yields of up to 95% from the treatment of the thiosemicarbazides with aldehyde derivatives having methoxy and hydroxyl groups. The structures of the synthesized molecules were elucidated with elemental analysis and FT–IR, 1H NMR, and 13C NMR spectroscopic methods. The electronic and spectroscopic properties of the compounds were determined by the DFT calculations performed at the B3LYP/6‐311++G(2d,2p) level of theory, and the experimental findings were supported. They exhibited a highly potent inhibition effect on acetylcholinesterase (AChE) and carbonic anhydrases (hCAs) (KI values are in the range of 23.54±4.34 to 185.90±26.16 nM, 103.90±23.49 to 325.90 ±77.99 nM, and 86.15±18.58 to 287.70±43.09 nM for AChE, hCA I, and hCA II, respectively). Furthermore, molecular docking simulations were performed to explain each enzyme‐ligand complex's interaction.
