[PMID: 37225028 DOI: 10.1016/j.jep.2023.116654] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 05/16/2023] [Accepted: 05/16/2023] [Indexed: 05/26/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The leave paste of the plant, Eupatorium glandulosum H. B & K, has been traditionally used to treat cuts and wounds by the tribal community of the Nilgiris district of Tamilnadu, India. AIM OF THE STUDY The present study was carried out to investigate the wound healing potential of this plant extract and the compound, 1-Tetracosanol, isolated from the ethyl acetate fraction. MATERIALS AND METHODS An in vitro study was designed to compare the viability, migration and apoptosis of the fresh methanolic extract fractions and 1-Tetracosanol using mouse fibroblast NIH3T3 cell lines and human keratinocytes HaCaT cell lines, respectively. 1-Tetracosanol was evaluated for its viability, migration, qPCR analysis, in silico, in vitro and in vivo. RESULTS 1-Tetracosanol at the concentration of 800, 1600, 3200 μM has significant wound closure of 99% at 24 h. The compound when screened in silico against various wound healing markers, TNF-α, IL-12, IL-18, GM-CSF and MMP-9, revealed high binding energy of -5, 4.9 and -6.4 kcal/mol for TNF-α, IL-18 and MMP-9, respectively. Gene expression and the release of cytokines increased at an early stage of the wound repair. 1-Tetracosanol, at 2% gel showed 97.35 ± 2.06% wound closure at 21st day. CONCLUSION 1-Tetracosanol is a good lead for drug development targeted towards wound healing activity and work in this direction is in progress.

Abstract
Seven undescribed compounds, including four acridones, two coumarins, and a phenylpropanoid, together with 13 known acridone analogues were isolated from the ethanolic extract of the stems and leaves of Glycosmis ovoidea Pierre. Their structures were elucidated on the basis of comprehensive analysis of 1D and 2D NMR and HRESIMS spectroscopic data, and the absolute configurations were assigned by comparison of the experimental and calculated ECD data. Five compounds showed moderate inhibitory effects on nitric oxide production stimulated by lipopolysaccharide in BV-2 microglial cells with IC50 values in the range of 18.30-30.84 μM, and three compounds showed potent inhibition on 5-lipoxygenase (5-LOX) with IC50 values in the range of 2.08-10.26 μM. The possible binding sites of the active compounds with 5-LOX were further performed by molecular docking.

Abstract
Abstract
Murrayafoline A (MuA) is a natural compound with diverse biological activities, including cytotoxicity against cancer cells, but suffers from poor water solubility and low specificity. In order to improve the potential of MuA as a candidate for cancer treatment, MuA-loaded liposomes were prepared with the liposomal membrane consisting of dioleoylphosphatidylcholine and cholesterol. Dynamic light scattering measurements showed that the MuA-loaded liposomes had a z-average particle size of 104.3 ± 6.4 nm (mean ± SD; n = 3) and a polydispersity index of 0.15 ± 0.02 (mean ± SD; n = 3). The encapsulation efficiency was 55.3 ± 2.3% (mean ± SD; n = 3). The in vitro cytotoxicity of encapsulated MuA was attenuated at IC50 = 21.97 µg/mL compared to 6.24 µg/mL for free MuA, against HepG2. In contrast, MuA-loaded liposomes were significantly more effective at inhibiting cell growth in HepG2 cancer spheroids, which indicated that they were able to reach the interior layers of the microtumor. Taken together, these results showed that the encapsulation of MuA in liposomes is a good research direction to improve this natural compound’s potential as a candidate for cancer treatment.

[PMID: 34314905 DOI: 10.1016/j.phytochem.2021.112865] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 06/28/2021] [Accepted: 06/30/2021] [Indexed: 06/13/2023]
Abstract
The present article is a systematic and constructive review of the traditional medicinal uses, chemistry, pharmacology, toxicology, and formulation aspects of Glycosmis species. The genus Glycosmis comprise 51 accepted species broadly distributed in Australia, China, India, and South-East Asia. Traditionally, Glycosmis species are used in folk medicines to treat cancer, anaemia, rheumatism, fever, cough, liver-related problems, skin ailments, intestinal worm infections, wounds, and facial inflammation. This review aims to provide readers with the latest information highlighting chemical constituents isolated from the Glycosmis species, plant parts utilized for their isolation and their pharmacological activities. So far, 307 chemical constituents have been isolated and characterized from different species of the genus Glycosmis; among these constituents, alkaloids, flavonoids, terpenoids, phenolics, and sulphur-containing amides are the major bioactive compounds. Modern pharmacological studies have shown that the crude extracts and compounds isolated from this genus exhibit a broad spectrum of biological activities like anticancer, antimicrobial, anti-inflammatory, antipyretic, antidiabetic, antioxidant, larvicidal, insecticidal, hepatoprotective, wound healing, antiviral, antidiarrheal, and anxiolytic. The carbazole and acridone alkaloids from this genus have shown potential anticancer activity in various in vitro and in vivo studies. Rare scaffolds like dimeric carbazoles, dimeric acridone alkaloids, flavanocoumarins and sulphur-containing amides from this genus need further exploration for their potential bioactivity. This article also briefs about the toxicological screening and discusses various polyherbal and nano formulation aspects of Glycosmis species. Most of the pharmacological studies reported from this genus were carried out in vitro. An in-depth in vivo and toxicology evaluation of the crude extracts and isolated specialized compounds is required to explore the full therapeutic potential of this genus.

Abstract
In diabetes mellitus, the wound healing process is impaired and delayed. Plants are actively investigated for safe, effective, and well-tolerated treatment options for wound. The plant Buddleja polystachya has a traditional claim for the treatment of wound. Fresh leaves are crushed and given for topical application. The objective of this study was to evaluate the wound healing activity of hydro-alcoholic extract and solvent fractions of leaves of B. polystachya fresen (Buddlejaceae) in normal and diabetic mice. METHOD B. polystachya leaves were extracted using 80% methanol and further fractionated using chloroform, ethyl acetate, and water. The wound healing activity was tested using excision, incision, and diabetic wound models. Area of wound contraction, time of epithelialization, and wound breaking strength were determined. RESULT Treatment with 5% w/w (P < 0 0.05) and 10% w/w (P < 0.001) crude extract of B. polystachya significantly lowered wound area as compared to simple ointment. Treatment of excision wound with 5% w/w and 10% w/w of chloroform, ethyl acetate, and aqueous fractions of B. polystachya significantly lowered wound area and epithelization period (P < 0.05). The 10% w/w extract of B. polystachya showed a significant area of diabetic wound contraction compared to 5% w/w extract and simple ointment. The 10% w/w and 5% w/w extracts of B. polystachya significantly increased wound breaking strength compared to untreated and simple ointment groups (P < 0.05). CONCLUSION The crude and the solvent fractions of B. Polystachya leaves possess wound healing activities as evidenced by an increase in tensile strength and wound contraction rate and decrease in the epithelialization period. This finding supports the traditional claims of B. polystachya for the healing of wounds.

Abstract
Background Medicinal plants play an important role in treating various diseases. Vernonia auriculifera Hiern is one of the medicinal plants used traditionally for the management of wounds. However, there were no scientific reports documented so far on the wound healing activities to substantiate the claim. Thus, the present study provides a scientific evaluation for the wound healing potential of the crude extract as well as solvent fractions of the leaves of Vernonia auriculifera Hiern. Methods Extraction was carried out by maceration using 80% methanol and part of the crude extract fractionated with chloroform, ethyl acetate, and aqueous solvents. Simple ointment bases were prepared using hard paraffin, cetostearyl alcohol, white soft paraffin and wool fat according to British Pharmacopoeia. Then, two types of ointment formulations were prepared from the extract, ie, 5% w/w and 10% w/w. Mice and rats were employed for wound healing study and dermal toxicity test, respectively. Wound healing effects were evaluated by percent of wound contraction, period of epithelialization, tensile strength, and histological analysis as parameters in excision, incision, and burn wound models. Finally, the data were expressed as mean ± SEM, and the results were analyzed using one-way ANOVA followed by post hoc Tukey-test. Results In the excision wound model, the 10% w/w crude extract ointment showed significant wound contraction (P < 0.001) from day 4 to day 18 as compared to the negative control. Both the 5% w/w (P < 0.001) and 10% w/w (P < 0.05) crude extract ointments have showed statistically significant difference in epithelialization period as compared to the negative control. Groups treated with the ethyl acetate and aqueous fractions ointments in incision wound model showed a statistically significant (P < 0.001) increase in tensile. The 10% w/w and 5% w/w ointments of the crude extract showed a significant (P < 0.001) increase in breaking strength compared to simple ointment and the untreated control groups. In burn wound model, significant reduction in epithelialization period was observed in 5% w/w (P < 0.05) and 10% w/w (P < 0.001), and the percentage of wound contraction was significantly increased in most of post wounding days by 10% w/w (P < 0.001) and 5% w/w (P < 0.05) crude extract ointments and compared to the negative control. Conclusion The crude, aqueous, and ethyl acetate fraction of Vernonia auriculifera leaves possess wound healing activities. This finding justifies the use of the leaves of this plant for wound healing as claimed in the traditional medicine literature.

Abstract
Callicarpa nudiflora has been widely used in Li nationality medicine and treated burns and scalds in China. Our objective was to preliminarily elucidate healing effect and action mechanism of Callicarpa nudiflora water extract (CNE) on the scald wounds using an experimental rat mode. The second-degree scald wounds were induced by hot water on dorsal surface of Sprague-Dawley (SD) rats, and then they were randomly divided into 5 groups as follows: control (CON), Vaseline, Silver sulfadiazine (SSD), and Vaseline supplemented with 10% and 20% CNE groups. These ointments were employed locally once daily for 21 days. The macroscopic analysis showed CNE significantly accelerated the wound healing process and lowered the wound areas on days 15, 18, and 21 especially in 20% CNE group compared to CON group. Histopathological evaluation showed the mildly hypertrophic epidermis and the intact dermis in the 20% CNE-treated group were obviously distinguished from CON group on day 21. The CNE-treated groups had no obvious effect for TNF-α and IL-10 expressions on the second day and 14th day, while TGF-β1 expression level was decreased on the 21th day and VEGF level was increased on the 7th day in the 20% CNE group. Furthermore, the expression level of Samd3 was strongly inhibited in 20% CNE group. These findings suggested that the CNE can enhance the wound healing and skin repair in deep second-degree scald rats and thus support its traditional use.

Abstract
Hypertrophic scar is a complication of wound healing and has a high recurrence rate which can lead to significant abnormity in aesthetics and functions. To date, no ideal treatment method has been established. Meanwhile, the underlying mechanism of hypertrophic scarring has not been clearly defined. Although a large amount of scientific research has been reported on the use of medicinal plants as a natural source of treatment for hypertrophic scarring, it is currently scattered across a wide range of publications. Therefore, a systematic summary and knowledge for future prospects are necessary to facilitate further medicinal plant research for their potential use as antihypertrophic scar agents. A bibliographic investigation was accomplished by focusing on medicinal plants which have been scientifically tested in vitro and/or in vivo and proved as potential agents for the treatment of hypertrophic scars. Although the chemical components and mechanisms of action of medicinal plants with antihypertrophic scarring potential have been investigated, many others remain unknown. More investigations and clinical trials are necessary to make use of these medical plants reasonably and phytotherapy is a promising therapeutic approach against hypertrophic scars.

Abstract
OBJECTIVE To evaluate the wound healing potential of fractions from ethanol extract of Martynia annua (M. annua) Linn leaves. METHODS Ethanol extract of M. annua Linn leaves was fractionate into three different fractions (MAF-A, MAF-B and MAF-C) which were screened for wound healing potential using two models: excision and incision on rats. The thin layer chromatography (TLC) profile of all fractions were analyzed and TLC of luteolin was also done. The Povidone-Iodine Ointment was used as reference for comparision. Excision and incision wounds were created on dorsal portion of rats for study. Wound contraction, biochemical parameters (protein level and hydroxyproline level) and histopathological study were performed in excision wound model whereas incision model was used for determination of tensile strength. RESULTS The wound contraction and tensile strength of skin tissues were observed significantly greater in MAF-C fraction treated group than other two fractions (P<0.01). In excision wound method (on day 18) protein content and hydroxyproline were found significantly higher in MAF-C group than control group (P<0.01). Histopathological study also showed better angiogenesis, matured collagen fibres and fibroblast cells as compared with the control group. CONCLUSIONS In conclusion, our findings suggest that fraction MAF-C from ethanol extract of M. annua leaves is found most effective in wound healing.

Topical application of Cleome viscosa increases the expression of basic fibroblast growth factor and type III collagen in rat cutaneous wound. BIOMED RESEARCH INTERNATIONAL 2014; 2014:680879. [PMID: 24864253 PMCID: PMC4016850 DOI: 10.1155/2014/680879] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/06/2014] [Revised: 03/10/2014] [Accepted: 03/26/2014] [Indexed: 02/02/2023]
Abstract
Cleome viscosa L. (Cleomaceae) is an important traditional medicine of the Indian-Ayurvedic and Chinese-medicine system documented for rheumatic arthritis, hypertension, malaria, neurasthenia, and wound healing. The plant is also known as Asian spider flower and is distributed throughout the greater part of India. The present study explored the wound healing property of C. viscosa methanol extract (CvME) and its related mechanism using Wistar rat cutaneous excision wound model. Wound contraction rate, hydroxyproline quantification, and histopathological examination of wound granulation tissue were performed. The healing potential was comparatively assessed with a reference gentamicin sulfate hydrogel (0.01% w/w). Western blot for COL3A1, bFGF, and Smad-2, Smad-3, Smad-4, and Smad-7 was performed with 7-day postoperative granulation tissue. Results revealed that the topical application of CvME (2.5% w/w) significantly accelerated the wound contraction rate (95.14%, 24 postoperative days), increased the hydroxyproline content (3.947 mg/100 mg tissue), and improved histopathology of wound tissue as compared to control groups. Western blot analysis revealed that CvME significantly upregulated the expression of COL3A1 and bFGF and increased the Smad-mediated collagen production in granulation tissue. These findings suggest that C. viscosa promoted the wound repair process by attenuating the Smad-mediated collagen production in wound granulation tissue.

Abstract
Leaves of Croton adamantinus have been used to treat inflammation and skin wounds in the semi-arid area of the Northeast of Brazil. In order to evaluate if the essential oil (EO) was responsible for the claimed activities; antinociceptive, wound healing and antimicrobial tests were carried out. Twenty constituents were identified in C. adamantinus EO by GC-MS, ¹H-NMR and ¹³C-NMR, the major compounds being methyl-eugenol (14.81%) and 1,8-cineol (13.74%). Antinociceptive activity was evaluated by the formalin test and the abdominal contortion assay in mice. The EO (50 and 100 mg/kg) decreased the licking time of both phases of the formalin test when compared to the vehicle, but not to morphine (7.5 mg/kg). In the abdominal contortion assay, the EO (50 and 100 mg/kg) reduced the number of contortions compared to the vehicle and to indometacin (10 mg/kg). The wound healing activity was verified also using two experimental models: excisional wound and dead space. Topical treatment with the EO (1%) increased the wound contraction from the third day of treatment (compared with nitrofurazone 0.2%), while systemic treatment (50 mg/kg/day) increased granulation tissue formation and reduced the water content. C. adamantinus EO also showed antimicrobial activity against Staphylococcus aureus in disk diffusion method. These results corroborate the ethnobotanical use of this specie by Brazilian population.
