Abstract
A metal-free photosensitized 1,2-imino-sulfamoylation of olefins by employing a tailor-made sulfamoyl carbamate as the difunctionalization reagent has been established. This protocol exhibits versatility across a broad substrate scope, including aryl and aliphatic alkenes, leading to the synthesis of diverse β-imino sulfonamides in moderate to good yields. This method is characterized by its metal-free reaction system, mild reaction conditions, excellent regioselectivity, and high atom economy, serving as a promising platform for the preparation of β-amino sulfonamide-containing molecules, particularly in the context of drug discovery.

Abstract
1,2,3-Triazolylidene MIC M-complexes (M = Au, Pd, Pt) having 2-azetidinones and penicillin G substituents at the triazole ring were prepared by CuAAC on 2-azetidinones having a terminal alkyne tethered at N1, followed by alkylation of the 1,2,3-triazole ring and transmetallation [Au(I), Pd(II) and Pt(II)]. The Au-MIC complexes efficiently catalyze the regioselective cycloisomerization of enynes, while the Pt-MIC complexes were efficient catalysts in hydrosilylation reactions.

Abstract
A new diphenylamine derivative, scediphenylamine A (1), together with six phthalimide derivatives (2-7) and ten other known compounds (8-17) were obtained from the marine-derived fungus Scedosporium apiospermum F41-1 fed with synthetically prepared anthranilic acid and phthalimide. The structure and absolute configuration of the new compound were determined by HRMS, NMR, and X-ray crystallography. Evaluation of their lipid-lowering effect in 3T3-L1 adipocytes showed that scediphenylamine A (1), N-phthaloyl-tryptophan-methyl ester (4), 5-(1,3-dioxoisoindolin-2-yl) pentanamide (5), perlolyrine (10) and flazine (11) significantly reduced triglyceride level in 3T3-L1 cells by inhibiting adipogenic differentiation and synthesis with the EC50 values of 4.39, 2.79, 3.76, 0.09, and 4.52 μM, respectively. Among them, perlolyrine (10) showed the most potent activity, making it a candidate for further development as a potential agent to treat hyperlipidemia.

Abstract
PURPOSE The development of resistance to available anticancer drugs is increasingly becoming a major challenge and new chemical entities could be unveiled to compensate this therapeutic failure. The current study demonstrated the synthesis of 2-aminothiazole [S3(a-d) and S5(a-d)] and 2-aminopyridine [S4(a-d) and S6(a-d)] derivatives that can target multiple cellular networks implicated in cancer development. METHODS Biological assays were performed to investigate the antioxidant and anticancer potential of synthesized compounds. Redox imbalance and oxidative stress are hallmarks of cancer, therefore, synthesized compounds were preliminarily screened for their antioxidant activity using DPPH assay, and further five derivatives S3b, S3c, S4c, S5b, and S6c, with significant antioxidant potential, were selected for investigation of in vitro anticancer potential. The cytotoxic activities were evaluated against the parent (A2780) and cisplatin-resistant (A2780CISR) ovarian cancer cell lines. Further, Molecular docking studies of active compounds were performed to determine binding affinities. RESULTS Results revealed that S3c, S5b, and S6c displayed promising inhibition in cisplatin-resistant cell lines in comparison to parent cells in terms of both resistance factor (RF) and IC50 values. Moreover, S3c proved to be most active compound in both parent and resistant cell lines with IC50 values 15.57 µM and 11.52 µM respectively. Our docking studies demonstrated that compounds S3c, S5b, and S6c exhibited significant binding affinity with multiple protein targets of the signaling cascade. CONCLUSION Anticancer activities of compounds S3c, S5b, and S6c in cisplatin-resistant cell lines suggested that these ligands may contribute as lead compounds for the development of new anticancer drugs.

Abstract
Background: These days epilepsy is a common neurological disorder, which can affect on quality of life by unpredictable seizure. Thalidomide is one of the drugs to control the epilepsy but side effects such as teratogenicity, made it difficult to use. Methods: Six new analogues of N-aryl-4-(1,3-dioxoisoindolin-2-yl)benzamides were synthesized and tested for anti-seizure activity. To evaluate the anti-seizure activity of these new derivatives, 40 mice in 8 groups were received 10 mg/Kg of each new derivatives 30 min before the injection of pentylenetetrazole (PTZ, 70 mg/kg) to induced seizures. Latency time to first symptom of seizure was measured and compared to vehicle and standard groups. Docking methodology was applied to study on mode of interaction between GABAA receptor and synthetized compounds. Results: Structures of the all synthesized compounds were confirmed by NMR and mass spectroscopy. The latency time and mortality rate were individually measured for an hour after injection of pentylenetetrazole. Docking study revealed that synthesized compounds and thalidomide interact in similar conformation with GABAA receptor. Conclusion: The experimental and docking results were found in good correlation and demonstrated that the most active compound (5a), with 3,4-dimethylphenyl residue increased the duration of seizure inhibition threshold in comparison with thalidomide.

Abstract
There are several limited approaches to treat epilepsy in hospitals, for example, using medicines, surgery, electrical stimulation and dietary interventions. Despite the availability of all these new and old approaches, seizure is particularly difficult to manage. The quest for new antiepileptic molecules with more specificity and less CNS toxicity continues for medicinal chemists until a new and ideal drug arrives. This review covers new antiseizure molecules of different chemical classes, the exact mode of action of which is still unidentified. Newer agents include sulfonamides, thiadiazoles, semi- and thiosemicarbazones, pyrrolidine-2,5-diones, imidazoles, benzothiazoles and amino acid deriva tives. These new chemical entities can be useful for the design and development of forthcoming antiseizure agents.

Abstract
The stereoisomers of N-phthaloyl-protected amino acids and dipeptidomimetics were separated on macrocyclic glycopeptide and cellulose-based chiral stationary phases (CSPs) in the RP and polar-ionic modes. The effects of the organic modifier, the mobile phase composition, and the pH on the separations were investigated. Optimization of these separations was achieved through variation of the mobile-phase additive combinations. The elution sequence was determined for some of the samples. A practical application for the monitoring of the reaction conditions for N-phthaloylation of (S)-Phe was demonstrated.

Abstract
Two series of pharmacophoric hybrids of phthalimide-GABA-anilides/hydrazones were designed and synthesized and evaluated for their anticonvulsant and neurotoxic properties. The structures of the synthesized compounds were confirmed by the use of their spectral data besides elemental analysis. Initial anticonvulsant screening was performed using intraperitoneal (i.p.) maximal electroshock-induced seizure (MES), subcutaneous pentylenetetrazole (scPTZ), subcutaneous strychnine (scSTY), and intraperitoneal picrotoxin (ipPIC)-induced seizure threshold tests. All of the compounds were ineffective in the MES test. Most of the compounds were found to be effective in the scSTY and ipPIC models and very few compounds showed protection in the scPTZ model.

Abstract
A series of thiourea and guanidinium derivatives have been prepared and their ability to bind a carboxylate group has been investigated. Guanidinium 33, featuring two additional amides and a pyridine moiety, proved to be the most potent carboxylate binding site and was able to bind acetate in aqueous solvent systems (K(ass) = 480 M(-1) in 30% H(2)O-DMSO). The pyridine moiety is critical to obtaining strong binding, and comparison with the binding properties of analogous compounds in which the pyridine is replaced by a benzene ring provides a striking example of enthalpy-entropy compensation.

Abstract
A series of N-substituted-1,3-isoindolinedione derivatives (2-16) were synthesized for the purpose of defining the effect of N-substitution on the anticonvulsant activity of these derivatives. The target compounds (2-16) were obtained by condensation of phthalic anhydride with the corresponding amine derivative. The structures of the synthesized derivatives (2-16) were confirmed by means of IR, 1H-NMR, 13C-NMR, MS and elemental analyses. The anticonvulsant activity of all compounds (2-16) were evaluated by subcutaneous pentylenetetrazole seizure threshold test at doses of 0.2, 0.4 and 0.8 mmol/kg compared with sodium valproate as a positive control. Their neurotoxicity were determined by the rotorod test. Many of the present series of compounds showed good anticonvulsant activity at the tested doses, as compared to sodium valproate. Three of them (4, 6 and 11) exhibited 100% protection against convulsions, neurotoxicity and death at all tested doses. Out of the series, two compounds (12 and 13) were completely inactive with 100% mortality. 3-(p-chlorophenyl)-4-(1,3-dioxo-2,3-dihydro-1H-2-isoindolyl)butanoic acid derivative (11) has emerged as the most active compound which is 20 times more active than valproate with ED50 8.7, 169 mg/kg; TD50 413, 406 mg/kg and PI 47.5, 2.4. The results revealed the importance of the combination of baclofenic and phthalimide moieties (compound 11) as a promising anticonvulsant candidate.

Abstract
Alpidem analogues containing a GABA (1-3) or glycine (4-6) moiety were synthesized and their interaction with the GABA/benzodiazepine receptor complex at central (CBR) and peripheral (PBR) level was evaluated. In particular, their ability to modulate the specific binding of [3H]-GABA to washed membrane preparations from the rat cerebral cortex, as well as their effects on human recombinant GABA(A) receptors in Xenopus laevis oocytes, were assessed. Results from these in vitro assays showed that the most active compounds were 1 and 4. Intraperitoneal administration of compound 1 at a dose of 150 mg/kg significantly antagonized pentylenetetrazole-induced seizures in rats and the protective effects were evident for 90 min. However, compound 4 failed to interact with strychnine-sensitive Gly-binding sites. Consistent with these binding results, intraperitoneal administration of compound 4 at 150 mg/kg showed no effect against convulsions induced by strychnine, except for a prolonged time of the latency of convulsions. The results obtained suggest that compound 1 possesses interesting anticonvulsant activity and deserves further investigation as a novel lipophilic GABA derivative.
