Abstract In this study, hymecromone with known therapeutic aspects was conjugated steroids a class of natural products that widely exhibited broad biological functions. Cholic acid, diosgenin, cholesterol, DHEA, and testosterone were selected as steroid moiety, each which has different mechanism action. This study focused on developing novel conjugates can be used multi‐targeted drugs for treating various diseases. All evaluated in vitro their antiproliferative antimicrobial activities discussed the structure‐activity relationship. The 5 6 comparable cytotoxic effects to reference against cancer cell lines (K562, MCF‐7, HeLa) while showing no toxicity healthy cells (L929).

Ephedra foeminea is traditionally used to treat breast cancer in several Arab countries. Scientific studies have reported different effects of this plant on some cell lines. The current study determined the anti-cancer potential methanolic extract against four types lines in-vitro. was prepared by maceration and phytoconstituents were identified LC-MS analysis. IC50 value MDA-MB-231, MCF-7, 4T1, MCF-10 using MTT assay. Further investigations carried out concentration (40.09 µg/ml) determine live/dead cells acridine orange/ethidium bromide staining. effect expression reactive oxygen species (ROS) evaluated flow cytometry. results analyzed one-way ANOVA followed Tukey's test. analysis revealed presence 34 30 positive negative modes respectively. most effective 4T1 a dose-dependent manner (P<0.001) with an 40.09 µg/ml showed negligible cells. It increased apoptosis 77.84% cells, as also ROS 39.57% that possesses increasing inducing result suggests foemenia reasonable due its oxidative pathways. confirm traditional belief cancer.

Novel coumarin derivatives were synthesised and tested for their cytotoxicity against human cancer cells (PC-3 MDA-MB-231). Compounds 5, 4b, 4a possessed potent cytotoxic activity PC-3 with IC50 3.56, 8.99, 10.22 µM, respectively. Compound 4c displayed more than erlotinib in the MDA-MB-231 8.5 µM. Moreover, compound 5 exhibited inhibitory on EFGR 0.1812 as well PI3Kβ that was twofold higher LY294002, suggesting this has a dual EGFR inhibiting activity. Docking aligns vitro results sheds light molecular mechanisms underlying targeting. Furthermore, decreased AKT m-TOR expression cells, showing it specifically targets these via EGFR/PI3K/Akt/m-TOR signalling pathway. Simultaneously, caused cell cycle arrest at S phase induced activation of both intrinsic extrinsic apoptotic pathways.

The objective of the study was to determine total phenolic and flavonoid contents (TPC TFC, respectively), as well solvent-partitioned fractions, leaf extract Cassia fistula. Using DPPH, TAC, FRAP tests, in vitro antioxidant properties crude its ethyl acetate fraction were investigated. Additionally, C. fistula chemical profiling accomplished using LC-ESI-MS/MS. Along with that, effectiveness (200 400 mg/kg) treating male rats ulcerative colitis (UC) induced by acetic acid assessed. According findings, had highest concentrations TPC (12.36 1.46 mg GAE/100 mg) TFC (5.12 0.64 QE/100 mg), impressive activity IC50 values DPPH (12.7 g/mL), (4.87 0.71 mM Fe+2/g), TAC (55. Fifty-five chemicals, predominantly phenolics (catechins, flavonoids, anthraquinones, chalcones, acids), detected LC/MS/MS. anti-UC effect dose-dependent. hematological parameters, liver biomarkers, oxidative stress, histopathology, immunohistochemistry revealed that prophylactic administration ameliorated all previous biomarkers. However, when administered on established colitis, it facilitated recovery inflamed mucosa showed better results than protection mode. phytoconstituents discovered here LC/MS/MS examined molecular docking studies for their binding affinities towards COX-2 caspase-3 proteins highlight anti-inflammatory antiapoptotic activities plant. Emodin compound displayed affinity proteins, while isorhamnetin have best associations essential amino acids caspase-3. Procyanidin B2 interestingly shows potent interactions important two targets. This has made possible utilize treatment UC clarified mechanism action.

Alzheimer's disease (AD) causes a great socioeconomic burden because of its increasing prevalence and the lack effective therapies. The multifactorial nature AD prompts researchers to search for new strategies discovering disease-modifying therapeutics. To this extent, multitarget approach holds potential synergic or cooperative activities arising from compounds that are properly designed address two more pathogenetic mechanisms. As privileged nature-friendly scaffold, coumarin has successfully been enrolled as heterocyclic core in design multipotent anti-Alzheimer's agents. Herein, we comprehensively summarize most recent literature (2018-2023), covering rational discovery coumarin-containing directed ligands (MTDLs) whose anti-AD profile encompassed at least different biological relevant onset progression. enhance clarity presentation, synthetic coumarin-based MTDLs categorized into four clusters based on their substitution pattern reported bioactivities: (i) mono-, (ii) di-, (iii) polysubstituted coumarins protein targets, (iv) targets with additional metal-chelating features. Before discussing multimodal coumarins, rationale addressing each target is briefly presented.

Different P450 isoforms may catalyze different types of reactions on the same substrate due to differences in their protein environments. To uncover how spatial environment within enzyme regulates reactivity, we conducted quantum mechanics/molecular mechanics (QM/MM) simulations CYP2A6-catalyzed 7-hydroxylation coumarin. The results revealed that water molecules can flexibly enter active site CYP2A6. In absence molecules, NIH shift mechanism was found be most favorable reaction pathway, leading keto intermediate further undergoes isomerization form C7-hydroxylated product. However, when are present at site, N-protonation route facilitated by waters and thus becomes preferred one. Both rationalize 1,2-H for aromatic hydroxylation reactions. This study highlights P450s employ diverse flexible mechanisms hydroxylation, offering deeper insight into P450-catalyzed
