Several natural products have been of help to humans, and its effect is noticeable in the medicinal world. Soursop with botanical name Annona muricata L. possesses antidiarrhea, anticold fever, antirheumatism, and antineuralgia properties. In this work, five selected molecular compounds were studied against type 3 of 3α-hydroxysteroid dehydrogenase (3α-HSD). Its anticancer activity was investigated using the quantum chemical method via Spartan 14 software, molecular docking via Discovery studio 2017, AutoDock Tool 1.5.6, AutoDock Vina 1.1.2, and PyMol 1.7.4.4 and the molecular dynamic simulation method via AMBER14 molecular dynamics package. Many descriptors (EHOMO, ELUMO, dipole moment, energy bandgap, area, volume, polarizability, polar surface area, Log P, hydrogen bond donor, and hydrogen bond acceptor) which describe the anticancer activity of the studied compounds were obtained. Also, the docking study revealed the inhibiting ability of the studied compound, and it was observed that compound C possesses a greater ability to inhibit than other studied compounds as well as the standard (5FU).

Background: There is an increasing need for botanicals to be used as an alternative and complementary medicine in the management of male infertility. Male infertility has been a major health/social challenge to people all over the world. This study, therefore, investigated the ameliorative potential of hydroethanolic leaf extract of Parquetina nigrescens (HELEPN) against d-galactose-induced testicular injury. Methods: Thirty male Wistar rats were randomly allotted into six groups (n = 5). Group I (Normal control), Group II (300 mg/kg b.w. d-galactose), Group III and IV (250 and 500 mg/kg b.w. HELEPN, respectively), Group V and VI (both received 300 mg/kg b.w. of d-galactose with 250 and 500 mg/kg b.w of HELEPN, respectively). d-galactose administration started two weeks prior to HELEPN treatment which lasted for six weeks. All assays were carried out using established protocols. Results: Administration of HELEPN at 250mg/kg and 500mg/kg concomitantly with d-galactose improved paired and relative testicular weights, levels of gonadotropins (LH and FSH) and testosterone, and poor sperm quality. HELEPN treatment reduced the levels of oxidative stress biomarkers (MDA, 8-OHDG, and AGEs) and inflammatory response (TNF-alpha and NO) to normal, as well as restoring the reduced activities of antioxidant enzymes (glutathione peroxidase, superoxide dismutase, and catalase). In addition, HELEPN treatment mitigated testicular DNA fragmentation and down-regulated caspase 3-activities. HELEPN at 500 mg/kg was observed to have the greatest ameliorative effect. Conclusion: HELEPN protects against d-galactose-induced testicular injury through antioxidative, anti-inflammatory, and antiapoptotic mechanisms.

Cardiovascular disorder is one of the causes of death globally. Quite a number of medicinal plants have been demonstrated to possess and exhibit beneficial effects on cardiovascular system throuhg their antioxidant properties. The study investigated the in vivo antioxidant properties of aqueous C. albidium pulp extract on isoproterenol-induced cardiotoxicity in albino rats. Cardiotoxicity was induced in rats by subcutaneous injection of ISO (85 mg/kg bwt) into adult albino rats and treated with the extract (100 and 200 mg/kg bwt). The levels of nitrite, lipid peroxidation, reduced glutathione total protein and activities of glutathione peroxidase, catalase and superoxide dismutase were evaluated using standard methods. The concentration of total protein was also determined. Administration of ISO (85 mg/kg body weight) caused significant (p < 0.05) reduction in the antioxidant status of animals. The enzymatic and non-enzymatic antioxidants perturbed by the administration of ISO were restored in the C. albidium treated rats. The study concludes that the aqueous extract of C. albidum pulp protected against Isoproterenol-induced cardiotoxicity in adult male Albino rats.

Aim: The study investigated the anti-hyperglycemic and anti-hyperlipidemic potentials of methanol extracts of Piper guineense and Aframomum melegueta leaves with a view to utilizing the plants in the treatment and management of cardiovascular disorders. Methodology: Twenty-eight healthy albino rats were randomly divided into seven equal groups: Group I received normal saline (2 ml/kg bwt); Group II received a single dose of alloxan(150 mg/kg bwt) intraperitoneally; Group III received  alloxan (150 mg/kg bwt) + glibenclamide (5 mg/kg bwt);Group IV received alloxan (150 mg/kg bwt) +PG (200 mg/kg bwt); Group V received alloxan (150 mg/kg bwt) + PG (400 mg/kg bwt); Group VI received alloxan (150 mg/kg bwt) + AM 200 (mg/kg bwt); Group VII received alloxan (150 mg/kg bwt) + AM (400 mg/kg bwt). The blood glucose level was determined before and after treatment with the extracts. The lipid: (total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL) were estimated using the Randox diagnostic kits. Results: The results revealed that alloxan was able to induce hyperglycemia at 150 mg/kg bwt and post-treatment with P. guineense and A. melegueta at 200 mg/kg and 400 mg/ kg bwt were able to significantly lower the blood glucose level which was quite apparent in AM treated groups. Also, the extracts at 200 mg/kg and 400 mg/kg were able to bring a significant (p < 0.05) reduction in TC, TG and LDL concentrations when compared to the alloxan treated group with the highest reduction in AM treated groups. Conclusion: These results revealed that the methanol extract of P. guineense and A. melegueta elicited anti-hyperglycemic and anti-hyperlipidemic potentials of the extracts with the highest effect observed in A. melegueta treated rats.
