Exploring the Potential of Saffron as a Therapeutic Agent in Depression Treatment: A Comparative Review.

Depression is a significant mental health challenge globally. While traditional antidepressants are effective, they often have unwanted side effects. Saffron, a natural spice derived from Crocus sativus L., has emerged as a potential alternative therapy for depression. Researchers have found that its components such as crocin, crocetin, and safranal have been found to mitigate depressive symptoms through neurotransmitter regulation, anti-inflammatory effects, and neuroprotection. Clinical trials suggest that the effectiveness of saffron in treating mild to moderate depression is comparable to that of standard medications, and animal studies support these results, showing behavioral improvements with saffron treatment. Saffron is particularly appealing due to its safety and lower incidence of side effects, making it suitable for those sensitive to conventional drugs. Additionally, its antioxidant properties may offer further health benefits. However, challenges such as determining the appropriate dosage, prohibitive cost, and the limited availability of quality saffron need to be addressed. Most research on saffron's efficacy is short-term; thus, long-term studies are essential to understand its full therapeutic potential and ongoing antidepressant effects. While saffron is safe in terms of its culinary value, higher therapeutic doses require careful monitoring for drug interactions and side effects. In summary, saffron represents a promising direction in depression treatment, with benefits potentially matching those of standard treatments and a better safety profile. However, further research is necessary to establish clear guidelines for its use, optimize dosing, and assess long-term outcomes. Saffron offers a natural treatment path for depression, but its use must be controlled and supported by scientific evidence.

Strategies to increase the secondary metabolite production, obtained from medicinal plants has been the topic of research in recent years. The symbiotic interaction between arbuscular mycorrhizal fungi and plants allows host-fungus pairings to enhance secondary metabolite synthesis. Therefore, the current study investigated the effect of inoculating two distinct AMF species discretely as well as in conjunction on the flower-derived secondary metabolites in Gomphrena globosa. The findings showed that the plants inoculated with combined treatment exhibited higher total phenolic (50.11 mg GAE/g DW), flavonoids (29.67 mg QE/g DW), saponins (122.55 mg DE/g DW), tannins (165.71 TAE/g DW) and terpenoid (8.24 mg LE/g DW) content in the methanolic extract. HPTLC examination showed the existence of kaempferol and benzoic acid with the highest amount (0.90% and 5.83% respectively) observed in the same treatment. FTIR analysis revealed functional group peaks with increased peak intensity in the combination treatment. Higher antioxidant activities such as DPPH (IC50: 401.39 µg/mL), ABTS (IC50: 71.18 µg/mL) and FRAP (8774.73 µM Fe (II) equivalent) were observed in the methanolic extract of combined treatment. To our knowledge, this is the first study on the impact of AMF inoculation on bioactive compounds and antioxidant activities in G. globosa flowers.

Deciphering the multi-scale mechanism of herbal phytoconstituents in targeting breast cancer: a computational pharmacological perspective.

Breast Cancer (BC) is the most common cause of cancer-associated deaths in females worldwide. Despite advancements in BC treatment driven by extensive characterization of its molecular hallmarks, challenges such as drug resistance, tumor relapse, and metastasis persist. Therefore, there is an urgent need for alternative treatment approaches with multi-modal efficacy to overcome these hurdles. In this context, natural bioactives are increasingly recognized for their pivotal role as anti-cancer compounds. This study focuses on predicting molecular targets for key herbal phytoconstituents-gallic acid, piperine, quercetin, resveratrol, and beta-sitosterol-present in the polyherbal formulation, Krishnadi Churna. Using an in-silico network pharmacology model, key genes were identified and docked against these marker compounds and controls. Mammary carcinoma emerged as the most significant phenotype of the putative targets. Analysis of an online database revealed that out of 135 predicted targets, 134 were mutated in breast cancer patients. Notably, ESR1, CYP19A1, and EGFR were identified as key genes which are known to regulate the BC progression. Docking studies demonstrated that the herbal phytoconstituents had similar or better docking scores than positive controls for these key genes, with convincing protein-ligand interactions confirmed by molecular dynamics simulations, MM/GBSA and free energy landscape (FEL) analysis. Overall, this study highlights the predictive potential of herbal phytoconstituents in targeting BC genes, suggesting their promise as a basis for developing new therapeutic formulations for BC.

Optimization of microwave parameters to enhance phytochemicals, antioxidants and metabolite profile of de-oiled rice bran.

The current study explores the effects of microwave treatment at varying wattage and durations on the phytoconstituents, antioxidant status, anti-nutritional factors (ANFs), and metabolite profiles of de-oiled rice bran. The total phenolics and flavonoids showed both increases and decreases depending on specific microwave parameters, while flavonol content consistently increased across all treated groups compared to the control. The DPPH and ABTS free radical scavenging activity, total antioxidant capacity, FRAP, CUPRAC, metal chelating activity, and ascorbic acid content were enhanced in most of the microwaved samples; however, longer microwave exposure at higher wattage led to their reduction. A treatment-specific decrease in ANFs, including condensed tannins, oxalates, and phytates, was observed. HRMS-based untargeted metabolomics identified a diverse range of primary and secondary metabolites, which clustered in a group-specific manner, indicating notable group-wise metabolite variations. Analysis of discriminating metabolites revealed no significant differences in the overall levels of phenolics, flavonoids, vitamins and cofactors, sugars, amino acids, terpenoids, fatty acids, and their derivatives among the treated groups compared to the control; however, several individual metabolites within these metabolite classes differed significantly. These findings suggest that optimized microwaving of de-oiled rice bran can enhance phytochemicals and antioxidants while improving the metabolite profile.

Phytoconstituents as modulator of inflammatory pathways for COVID-19: A comprehensive review and recommendations.

SARS-CoV-2 infection causes disruptions in inflammatory pathways, which fundamentally contribute to COVID-19 pathophysiology. The present review critically evaluates the gaps in scientific literature and presents the current status regarding the inflammatory signaling pathways in COVID-19. We propose that phytoconstituents can be used to treat COVID-19 associated inflammation, several already formulated in traditional medications. For this purpose, extensive literature analysis was conducted in the PubMed database to collect relevant in vitro, in vivo, and human patient studies where inflammation pathways were shown to be upregulated in COVID-19. Parallelly, scientific literature was screened for phytoconstituents with known cellular mechanisms implicated for inflammation or COVID-19 associated inflammation. Studies with insufficient evidence on cellular pathways for autophagy and mitophagy were considered out of scope and excluded from the study. The final analysis was visualized in figures and evaluated for accuracy. Our findings demonstrate the frequent participation of NF-κB, a transcription factor, in inflammatory signaling pathways linked to COVID-19. Moreover, the MAPK signaling pathway is also implicated in producing inflammatory molecules. Furthermore, it was also analyzed that the phytoconstituents with flavonoid and phenolic backbones could inhibit either the TLR4 receptor or its consecutive signaling molecules, thereby, decreasing NF-κB activity and suppressing cytokine production. Although, allopathy has treated the early phase of COVID-19, anti-inflammatory phytoconstituents and existing ayurvedic formulations may act on the COVID-19 associated inflammatory pathways and provide an additional treatment strategy. Therefore, we recommend the usage of flavonoids and phenolic phytoconstituents for the treatment of inflammation associated with COVID-19 infection and similar viral ailments.

Pre-clinical protective potentials of Carica papaya constituents in experimentally induced anemia.

OBJECTIVE: Anemia is a pathological condition characterized by reduced oxygen bioavailability and/or changes in hematological parameters. This study investigated the anti-anemic activities of Carica papaya (CP) phytoconstituents in aluminium-chloride-induced anemic rats. METHOD: Twenty-seven rats were randomized into nine groups of three rats as follows; group 1 was the normal (non-induced) group, 2-9 were anemic rats administered 1 mL distilled water, standard drug (3 mg/kg body weight (bw) ferrous sulphate), 100, 300 and 500 mg/kg bw of crude methanolic extract of CP (CMECP) of the leaf and 100, 300 and 500 mg/kg bw of CMECP of the seed respectively in the first stage of the study. In the second stage, thirty-three rats were randomized into eleven groups of three rats as follows; group 1 was the normal group, 2-11 were anemic rats treated with 1 mL distilled water, standard drug, 75 mg/kg bw, 150 mg/kg of alkaloid fraction of CP seed, 75 mg/kg bw, 150 mg/kg bw of flavonoid fraction of CP seed, 75 mg/kg bw and 150 mg/kg of alkaloid fraction of CP leaf, 75 mg/kg bw and 150 mg/kg bw of flavonoid fraction of CP leaf respectively. RESULTS: Treatment of anemic rats with CP extracts and fractions of the seed and leaf significantly reversed the hematological parameters and body weight of anemic rats in a dose independent fashion. The CMECP leaf at 100 and 500 mg/kg gave PCV of 42.50±0.50 and 47.00±0.50, while the seed gave 49.50±0.50 and 42.50±0.50 respectively after 2 weeks of treatment. However, the alkaloid and flavonoid fraction of CP presented better anti-anemic properties probably due to constituents' synergism. CONCLUSION: This study concluded that CP possesses phytoconstituents which potentiates it as a safe anti-anemic drug candidate.
