Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Many ethnopharmacological properties (anti-tumor, etc.) have been credited to Plectranthus esculentus tuber but the scientific basis has not been established. AIM OF THE STUDY To evaluate the effect of methanol extract of P. esculentus tuber (MEPET) (phase 1) and its fractions (phase 2) on benign prostatic hyperplasia (BPH) in rats. MATERIALS AND METHODS The study was conducted in two phases. Phase 1, thirty-five male albino rats (6 weeks old) were divided into seven groups of five rats each: normal control (NC) received olive oil (subcutaneously) and water (orally); disease control (DC) received testosterone propionate (TP) (3 mg/kg) and water; test groups (1,2,3 and 4) received TP + MEPET at 100, 200, 400, 600 mg/kg respectively; positive control, received TP + finasteride (5 mg/70 kg). After 28 days, their relative prostate weights (RPW) and prostate specific antigen (PSA) were determined. Phase 2, thirty rats were divided into 6 groups of 5 rats each: NC received olive oil (subcutaneously daily) and dimethyl sulfoxide (DMSO) (orally); DC received TP (3 mg/kg), and DMSO; test group 1 received TP and aqueous fraction of MEPET (400 mg/kg); test group 2 received TP and methanol fraction of MEPET (400 mg/kg); test group 3 received TP, and ethyl acetate fraction of MEPET (400 mg/kg); positive control received TP and finasteride (5 mg/70 kg). After 28 days, their erythrocyte sedimentation rates, RPW, prostate levels of PSA, DHT, inflammatory, apoptotic markers and prostate histology were determined. RESULTS Ethyl acetate fraction of MEPET modulated most of the parameters of BPH in the rats in a manner akin to finasteride as corroborated by prostate histology. CONCLUSIONS EFPET could be useful in the treatment of BPH.

Abstract
Steroid 5 alpha-reductase 2 (5αR-2) is a membrane-embedded protein that together with other isoforms plays a key role in the metabolism of steroids. This enzyme catalyzes the reduction of testosterone to the more potent ligand, dihydrotestosterone (DHT) in the prostate. Androgens, testosterone, and DHT play important roles in prostate growth, development, and function. At the same time, both testosterone and DHT have been implicated in the pathogenesis of benign prostate hyperplasia (BPH). Inhibition of the DHT formation, therefore, provides a therapeutic strategy that offers the possibility of preventing, delaying, or treating BPH. Currently, two steroidal drugs that inhibit 5αR-2, dutasteride and finasteride, have been approved for clinical use. These two come at a high cost and also portray undesirable sexual side effects which necessitate the need to find new chemotherapeutic alternatives for the disease. Based on the aforementioned, finasteride and dutasteride were subjected to scaffold hopping, fragment-based de novo design, molecular docking, and molecular dynamics simulations employing databases like ChEMBL, DrugBank, PubChem, ChemSpider, and Zinc15 in the identification of potential hits targeting 5αR-2. Altogether, ten novel compounds targeting 5αR-2 were identified with binding energies lower or comparable to finasteride and dutasteride, the main inhibitors for this target. Molecular docking and molecular dynamics simulations studies identify amino acid residues Glu57, Phe219, Phe223, and Leu224 to be critical for ligand binding and complex stability. The physicochemical and pharmacological profiling suggests the potential of the hit compounds to be drug-like and orally active. Similarly, the quality parameter assessments revealed the hits possess LELP greater than 3 implying their promise as lead-like molecules. The compounds A5, A9, and A10 were, respectively, predicted to treat prostate disorders with Pa (0.188, 0.361, and 0.270) and Pi (0.176, 0.050, and 0.093), while A8 and A9 were found to be associated with BPH treatment with Pa (0.09 and 0.127) and Pi (0.077 and 0.033), respectively. Structural similarity searches via DrugBank identified the drugs faropenem, acemetacin, estradiol valerate, and yohimbine to be useful for BPH treatment suggesting the de novo designed ligands as potential chemotherapeutic agents for treating this disease.

Investigation of the physicochemical properties of freeze-dried fruit pulp of Telfairia occidentalis and its potential use as suspending agent. Heliyon 2022; 8:e09997.

Abstract
Plant-based (natural) excipients can reduce the over reliance on synthetic ones. They have advantages such as low toxicity, biodegradability and low-cost relative to the synthetic ones. Telfairia occidentalis is a creeping plant that is cultivated for food in some African countries. The leaves, stem and root of the plant have been investigated as potential sources of medicine. This study aimed at evaluating the fruit pulp as a potential suspending agent. The ripe fruits of the plant were harvested and authenticated at the Department of Herbal Medicine, KNUST. The fruit pulp was extracted, freeze-dried and evaluated for its anti-microbial, phytochemical, physicochemical and anti-oxidant properties. Different concentrations of the dried pulp were used as a suspending agent in calamine lotion formulations, using bentonite as reference. The extract contained alkaloids, tannins, saponins, coumarins, glycosides, terpenoids magnesium and potassium. No antimicrobial and antioxidant activities were detected. The extract at all tested concentrations produced some level of suspendability. The test suspensions have good flow rates, high sedimentation volumes, high degree of flocculation, and relative ease of re-dispersion. However, these parameters were significantly (P < 0.05) lower (except flow rate) compared to those of bentonite as a suspending agent.

Res Rep Urol 2022; 14:225-239. [PMID: 35651598 PMCID: PMC9150786 DOI: 10.2147/rru.s365598] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 05/07/2022] [Indexed: 12/17/2022] Open
Abstract
Introduction Benign prostatic hyperplasia (BPH) is a major chronic disease affecting men, and the therapeutic agents currently used to manage it have significant side effects. As a result, an alternative medicine with improved therapeutic properties with no side effects is desperately needed. The current investigation aims to study whether the Caesalpinia bonduc seed extracts (ethanolic-A, hydroalcoholic-B, and aqueous-C) have inhibitory potential on testosterone propionate (TP)-induced BPH in Wistar rats. Methods Wistar rats (male) were randomly allocated to one of five groups: control, BPH (TP-3 mg/kg, subcutaneously daily), low dose (TP + C. bonduc seed extracts – 200 mg/kg body weight), high dose (TP + C. bonduc seed extracts – 400 mg/kg body weight), and standard drug (TP + finasteride – 10 mg/kg body weight). At the end of drug treatment, the rats were sacrificed and their serum and prostates were taken for biochemical and histological studies. Results C. bonduc seed extracts treatment significantly decreased prostate weight and prostatic index in rats with TP-induced BPH. The seed extracts exhibited a potent inhibitory effect on dihydrotestosterone (DHT) in serum and prostate. In addition, the PSA level in the serum showed a noteworthy decrease in comparison with the BPH group. Histopathological examination also indicated that extracts improved the tissue morphology of the prostate significantly. Out of three extracts tested, ethanolic and hydroalcoholic extract recorded significant effect. Finally, liquid chromatography quadrupole time-of-flight mass spectrometry (LC/MS-QTOF) analysis showed that the major compounds present in the extracts were tocopherols, fucosterol, linoleic acid, β-amyrin, β-sitosterol, campesterol, cassane furanoditerpene, norcassane furanoditerpene and other diterpenes. Conclusion Thus, C. bonduc seed extracts could be a potential source for the formulation of new drug for managing BPH. To the best of our knowledge, this is the first scientific animal investigation into the use of C. bonduc seed extract for the management of BPH.
