RESUMO

Tephorosia purpurea subsp. apollinea was extracted with methanol and n-hexane to obtain sub-fractions. The chemical compounds identified with GC-MS and HPLC in T. purpurea subsp. apollinea extracts showed antioxidant and anticancer properties. The antioxidant and anticancer activities were investigated using DDPH and ABTS assays, and MTT assay, respectively. Stigmasta-5,24(28)-dien-3-ol, (3 ß,24Z)-, 9,12,15-octadecatrienoic acid methyl ester, phytol, chlorogenic acid, and quercetin were the major chemical compounds detected in T. purpurea subsp. apollinea. These compounds possessed antioxidant and anticancer properties. The methanol extract showed antioxidant properties with DDPH and ABTS radical scavenging of 84% and 94%, respectively, relative to ascorbic acid and trolox. The anticancer effects of T. purpurea subsp. apollinea against the cancer cell lines MCF7 (IC50 = 102.8 ± 0.6 µg/mL), MG63 (IC50 = 118.3 ± 2.5 µg/mL), T47D (IC50 = 114.7 ± 1.0 µg/mL), HeLa (IC50 = 196.3 ± 2.3 µg/mL), and PC3 (IC50 = 117.7 ± 1.1 µg/mL) were greater than its anticancer effects against U379 (IC50 = 248.4 ± 7.5 µg/mL). However, it had no adverse effects on the normal cells (WI38) (IC50 = 242.9 ± 1.8 µg/mL). Therefore, the major active constituents presented in T. purpurea subsp. apollinea can be isolated and studied for their potential antioxidant and anticancer effects against breast, cervical, and prostate cancers and osteosarcoma.

RESUMO

Alzheimer's disease is regarded as a common neurodegenerative disease that may lead to dementia and the loss of memory. We report here the nootropic and anti-amnesic effects of both peppermint and rosemary oils using a rat model of scopolamine-induced amnesia-like AD. Rats were administered orally with two doses (50 and 100 mg/kg) of each single oil and combined oils. The positive group used donepezil (1 mg/kg). In the therapeutic phase, rats were administered scopolamine (1 mg/kg) through the oral administration of oils. During the nootropic phase, both oils showed a significant (p < 0.05) decrease in radial arm maze latency times, working memory, and reference memory errors compared with the normal group, along with significant (p < 0.05) enhancements of long-term memory during the passive avoidance test. Therapeutic phase results revealed significant enhancements of memory processing compared with the positive groups. In the hippocampus, oils exhibited an elevation of BDNF levels in a dose-dependent manner. Immunohistochemistry findings showed increased hippocampal neurogenesis suppressed by scopolamine in the sub-granular zone, and the anti-amnesic activity of single oil was enhanced when the two oils combined. Gas chromatography-mass spectrometry (GCMS) of the two oils revealed sufficient compounds (1,8-Cineole, α-Pinene, menthol and menthone) with potential efficacy in the memory process and cognitive defects. Our work suggests that both oils could enhance the performance of working and spatial memory, and when combined, more anti-amnesic activity was produced. A potential enhancement of hippocampal growth and neural plasticity was apparent with possible therapeutic activity to boost memory in AD patients.

RESUMO

Anti-tumor compounds from natural products are being investigated as possible alternatives for cancer chemotherapeutics that have serious adverse effects and tumor resistance. Calystegia silvatica was collected from the north coast of Egypt and extracted via methanol and n-hexane sub-fraction. The biologically active compounds of Calystegia silvatica were identified from the methanol and n-hexane extracts from the leaves and stems of the plant using GC-MS and HPLC. The antitumor properties of both parts of the plant were investigated against cancer and non-cancer cell lines using the MTT assay, and the IC50 in comparison to doxorubicin was calculated. The main compounds identified in the methanol extract were cis-vaccenic acid and trans-13-octadecenoic acid in the leaves and stems, respectively, and phenyl undecane and 3,7,11,15 tetramethyl-2-hexadeca-1-ol in the n-hexane extracts of the leaves and stems, respectively. Both parts of the plant contained fatty acids that have potential antitumor properties. The methanol extract from the stems of C. silvatica showed antitumor properties against HeLa, with an IC50 of 114 ± 5 µg/mL, PC3 with an IC50 of 137 ± 18 µg/mL and MCF7 with an IC50 of 172 ± 15 µg/mL, which were greater than Caco2, which had an IC50 of 353 ± 19 µg/mL, and HepG2, which had an IC50 of 236 ± 17 µg/mL. However, the leaf extract showed weak antitumor properties against all of the studied cancer cell lines (HeLa with an IC50 of 208 ± 13 µg/mL, PC3 with an IC50 of 336 ± 57 µg/mL, MCF7 with an IC50 of 324 ± 17 µg/mL, Caco2 with an IC50 of 682 ± 55 µg/mL and HepG2 with an IC50 of 593 ± 22 µg/mL). Neither part of the plant extract showed any cytotoxicity to the normal cells (WI38). Therefore, C. silvatica stems may potentially be used for the treatment of cervical, prostate and breast cancer.

RESUMO

This study aimed to see how effective Globularia arabica and Malva slyvestries-based cream formulations were at healing scald burn wounds in rats. Depending on ointment, preparations of 1%, 5%, and 10% w/w were created. For comparison, an ointment base and a regular burn cream composed soframycine were utilized. Rats introduced a burn by solidifying equipment at 100°C on a 14-mm2 shaved dorsal region. A deep second-degree burn was created, and the percentage of wound contraction was measured over the next 15 days. The rats were euthanized on days 8 and 15, and histological slides were prepared using hematoxylin and eosin staining. Compared to the control group, there was a substantial increase in wound contraction and a significant decrease in the duration of epithelialization in the based ointment-treated groups. However, as paralleled to Globularia arabica, significant (P < .05) results were observed with 10% Globularia arabica cream, whereas Malva slyverstries indicate minimal healing. Soframycine causes a substantial increase in wound contraction (P < .05). Soframycine cream with 10% Globularia arabica therapy resulted in practically complete re-epithelialization and re-structuring of wound tissue on histological examination, whereas Malva slyversries treatment resulted in low epithelization during treatment days. The findings suggest that Globularia arabica-based cream has the wound-healing capability.
