Isocarpine as A New Peperidine Alkaloid from Adenocarpus Complicatus with Anticandidal Activity
(Ingenta Connect, 2022) Alhılal, Mohammad; Alhılal, Suzan; Gomha, Sobhi
Background: Adenocarpus complicatus L. is one of Adenocarpus genus, which has about 50 species, from Fabaceae (Papilionaceae) family. This plant is found in the Mediterranean basin as a southern west part of Europe and North Afric forestes. Objective: Isolation of Isocarpine From Adenocarpus Complicatus as Anticandidal Agent. Methods: A new piperidine alkaloid Isocarpine was isolated from the aerial parts of Adenocarpus complicatus L., which is gross in Syria. The structure of the new compound was determined by UV, IR, EI-Ms, 1H-NMR, 13C-NMR, DEPT-135, DQF-COSY and HMQC. Results: The anticandidal activity of isocarpine was screened against 38 Candida strains and showed remarkable inhibitory effect compared with fluconazole as an antifungal reference drug. Conclusion: Isocarpine is antifungal agent.
Novel thiadiazole-thiazole hybrids: synthesis, molecular docking, and cytotoxicity evaluation against liver cancer cell lines
(Taylor & Francis Online, 2022) Alhılal, Mohammad; Alhılal, Suzan; Alhilal, Mohammad; Al-Humaidi, Jehan Y.; Alhilal, Suzan; Ahmed, Hoda A.; Gomha, Sobhi M.
One of the worst diseases, cancer claims millions of lives each year throughout the world, necessitating the creation of novel treatments. In this study, we designed a novel series of 1,3,4-thiadiazoles through the reaction of 2-(4-methyl-2-(2-(1-phenylethylidene)hydrazineyl)thiazole-5-carbonyl)-N-phenylhydrazine-1-carbothioamide (3) with the proper hydrazonoyl halides. Using the MTT assay, the newly synthesized thiadiazoles' growth-inhibitory potential against the liver cancer cell line HepG2-1 was assessed. In comparison to the standard drug doxorubicin (IC50 = 0.72 ± 0.52 µM), the results showed that two compounds, 16b and 21 (IC50 = 0.69 ± 0.41 and 1.82 ± 0.94 µM, respectively) had promising anticancer activity. The structural activity relationship (SAR) was investigated. In addition, molecular docking analysis onto quinone oxidoreductase2 (NQO2) receptor (PDB: 4ZVM) was investigated against the potent compounds to examine the reliability of the in vitro results. The newly prepared thiadiazole-thiazole hybrids are therefore regarded as potent anticancer drugs.
Osajin from Maclura pomifera alleviates sepsis-induced liver injury in rats: biochemical, histopathological and immunohistochemical estimation
(Taylor & Francis Online, 2023) Alhılal, Mohammad; Huseyin Serkan Erol, Serkan Yildirim, Ahmet Cakir, Murat Koc, Demet Celebi, Mesut Bunyami Halici
This paper aimed to examine the impact of flavonoid osajin (OSJ) on liver damage induced by sepsis. A total of 30 male rats were divided into 5 groups (Sham, sepsis, OSJ 150, OSJ 300 and reference). During sepsis, elevated lipid peroxidation (LPO) level and catalase activity (CAT) and decreased glutathione (GSH) level and superoxide dismutase (SOD) activity were observed in hepatic tissues of sepsis group in comparison with Sham group. A strong interleukin-33 and caspase-3 expressions were detected in hepatic tissues of sepsis group. On the contrary, OSJ administration to OSJ 300 group showed a significant decrease (P < 0.001) in LPO level (176±2.926) and significant increase (P < 0.001) in GSH level (10.586±0.083) and SOD activity (29.152±0.094) in comparison with sepsis group (185.777±1.735, 8.246±0.124, 24.307±0.379 respectively). In addition, the consumption of OSJ reduced expressions of interleukin-33 and caspase-3 and improved histopathological integrity. In conclusions, OSJ has hepatoprotective effect against sepsis-induced liver injury.
Synthesis and biological evaluation of new aza-acyclic nucleosides and their hydrogen complexes from indole
(SpringerLink, 2022) Alhılal, Suzan; Alhılal, Mohammad; Gomha, Sobhi M.; Ouf, Salama A.
Three novel aza-acyclic nucleosides and two hydrogen complexes were isolated by flash chromatography after being produced in a reaction between indole and dibenzosulfonyl diethylamine (which had previously been prepared) in the presence of sodium and absolute ethanol as a basic catalyst. Structures of new compounds and complexes were determined by 1D-NMR: 1H NMR, 13C NMR, DEPT-135, 2D-NMR: COSY, HMQC, HSQC, HMBC, IR, and MS spectroscopy. The synthesized compounds were evaluated against a wide range of microorganisms, including Gram-positive and Gram-negative bacteria as well as fungal strains. These compounds showed good biological activity.
Synthesis of Novel Acyclic Nucleoside Analogue Starting From 6-Aminouracil as Potent Antimicrobial Agent
(Polycyclic Aromatic Compounds, 2021) Alhılal, Mohammad; Alhılal, Suzan; Alhilal, Suzan; Gomha, Sobhi M.; Ouf, Salama A.
6-Aminouracil and 2-bromoethyl amine were prepared, as starting materials to be introduced as an alkylating reagent with sodium carbonate as a catalyst. Acyclic nucleoside was prepared for the first time, the expected structure of the final new compound 3 was determined based on IR, NMR, and mass spectroscopy, with safe and mild reaction conditions. The synthesized acyclic nucleoside has a potent and efficient antimicrobial activity compared to reference drugs particularly as an antibacterial agent, and can be used as an alternative to the commonly used antibiotics after performing the necessary biological research for its validation.
