PHARMACEUTICAL BIOLOGY 2022; 60:282-293. [PMID: 35138992 PMCID: PMC8843133 DOI: 10.1080/13880209.2021.2008455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 10/13/2021] [Accepted: 11/15/2021] [Indexed: 06/14/2023]
Abstract
CONTEXT Cordia dichotoma Forst. (Boraginaceae) has potent pharmacological impact. Meanwhile, its effect on fertility is unclear. OBJECTIVE This study investigates the effect of Cordia fresh fruits hydroethanolic extract on fertility. MATERIALS AND METHODS 120 Wistar albino male rats were divided into four groups (n = 30). The first group was negative control, and the second, third, and fourth groups received 125, 250, and 500 mg extract/kg bodyweight for 56 days. After 56 days, Cordia force-feeding stopped, and all groups were kept under laboratory conditions for another month to study the recovering effect. RESULTS After day 56, extract at 500 mg/kg significantly reduced sperm total count, motility%, and alive%, to 47.60 ± 2.27 × 106 sperm/mL, 43.33% ± 1.49, and 63.67% ± 1.19, respectively, abnormalities% increased considerably (26.67% ± 0.54), compared to the negative control. Also, significant depletion on follicle-stimulating hormone (2.66 ± 0.21 mIU/L), luteinizing hormone (1.07 ± 0.06 mIU/L), and testosterone (2.69 ± 0.13 nmol/L) level was recorded, compared to the negative control. Cordia negative effect showed on histopathological studies of testes, prostate, and seminal vesicles. Fortunately, these adverse effects of Cordia recovered remarkably after stopping administration for one month. CONCLUSIONS Cordia antifertility effect may be due to its hypocholesterolemic effect, where cholesterol, the steroid cycle precursor, was significantly reduced. This study can be incorporated in clinical research after being repeated on another small experimental animal, their offspring, and one large experimental animal, then going to a clinical study that we plan to do in the future.

Abstract
AbstractBackgroundAcknowledging population control to be an essential step for global health promotes wide research study in the area of male contraception. Although there are a great number of synthetic contraceptives available in the market, they have plenty of adverse effects. Different potential strategies for male contraception were investigated over a long period time consisting of hormonal, chemical, and immunological interventions, although these methods showed good antifertility results with low failure rates relative to condoms.Main textThis review is based upon the concept of herbal contraceptives which are an effective method for controlling the fertility of animals and humans. This review has highlighted herbal medicinal plants and plant extracts which have been reported to possess significant antifertility action in males. The review considers those plants which are used traditionally for their spermicidal and antispermatogenic activities and imbalance essential hormones for fertility purposes and plants with reported animal studies as well as some with human studies for antifertility effect along with their doses, chemical constituents, and mechanism of action of the antifertility effect of the plants. This review also explains the phases of sperm formation, hormone production, and the mechanism of male contraceptives.ConclusionAs far as the relevance of the current review is discussed, it might be quite useful in generating monographs on plants and recommendations on their use. A lot of the plant species listed here might appear promising as effective alternative oral fertility-regulating agents in males. Therefore, significant research into the chemical and biological properties of such less-explored plants is still needed to determine their contraceptive efficacy and also to possibly define their toxic effects so that these ingredients can be utilized with confidence to regulate male fertility. The new inventions in this field are necessary to concentrate on modern, more potent drugs with less harmful content and that are self-administrable, less costly, and entirely reversible.

Abstract
BACKGROUND This study was designed to evaluate the antifertility efficacy of eugenol (EUG) and Ocimum sanctum (OS) leaf extract in female albino rats. METHODS The healthy female albino rats were administered with EUG (99% pure) at a dose of 0.4 ml/day/rat and OS Linn. (Tulsi) leaf extract at a dose of 500 mg/kg body weight/day/rat orally for 15 days. One-way ANOVA analysis with Dunnetts multiple comparison test is used for analyzing data. RESULTS The total duration of estrous cycle was prolonged with EUG and no significant changes with OS leaf extract administration were observed. EUG elevated serum estradiol and progesterone levels but OS leaf extract elevates only progesterone levels. Elevated ovarian proteins were observed in both administrations. CONCLUSION This study concludes that the administration of EUG and OS leaf extract significantly enhanced the serum estradiol and progesterone levels leading to reduced frequency of ovulation and results in the impairment of fertility.

Abstract
Elevated serum interleukins (IL-6, IL-1β) over baseline concentration help in blastocyst adhesion to the uterine endometrium in the early phase of pregnancy. A nano PLA (Piperolactam A)-HPBCD (2-hydroxy-propyl-β-cyclodextrin) inclusion complex was developed as an interleukin down-regulator that exhibited 100% anti-implantation activity in rodents at a dose as low as 2.5-5.0 mg/kg. On metabolomics study, among major glyco-lipo-protein metabolites, only serum low-density lipoprotein (LDL) or very low-density lipoprotein (VLDL) levels revealed alteration by the formulation. Administration of PLA-HPBCD did not cause changes in serum estrogen and progesterone levels. However, IL-6 and IL-1β failed to increase post PLA-HPBCD administration; hence, it is assumed to be the mode of the drug's abortifacient action. In addition, absence of signs of either acute or chronic toxicity suggests the formulation was considerably non-toxic. Therefore, the nano-PLA conjugate promises as a non-steroidal contraceptive lead apart from ormeloxifene, the only non-steroidal anti-fertility agent currently available globally.

Abstract
BACKGROUND Recently, we reported high in vitro antibacterial efficacy of Althaea officinalis, Ziziphus jujuba, Cordia latifolia and Thymus vulgaris out of a total 21 plants against wide range of bacteria including MRSA. This study was therefore, designed to confirm efficacy of these four herbs against MRSA in an animal model. METHODS A pilot study was conducted to establish the dose of S. aureus (KY698020) required to induce clinical infection. Afterword, in main trial, efficacy of aforementioned plant extracts on the course of sore throat was checked by evaluating general health, gross lesion score, bacterial load and hematology in mice. RESULTS Pilot study revealed that 40 μl dose of 107 CFU/ml could induce infection which persist upto 08 days post infection. Mice treated with T. vulgaris and Z. jujuba showed reduction in gross lesion score of both heart and lungs. Treatment with only some plants could significantly decrease bacterial load of throat (T. vulgaris) heart, blood and joint (C. latifolia, and T. vulagris). Hematological indicators confirmed in vivo control of MRSA infection in all treatment groups except A. officinalis. CONCLUSION This is first report confirming in vivo anti-MRSA potential of C. latifolia and T. vulgaris and highlight the need to explore bioactive constituents of these plants. Moreover, previously reported in vitro antibacterial efficiency of A. officinalis could not be validated in current study.

Abstract
Abstract
Objectives
Introduction of multiple molecules in a single inclusion complex, albeit cheaper, lacks conclusive attempts in earlier drug delivery reports. This manuscript emphasizes simultaneous incorporation of two anticancer drugs, gefitinib (G) and simvastatin (S), in a single molecule of β-cyclodextrin for the first time to achieve effective drug delivery.
Methods
The inclusion complex (GSBCD) was prepared by cosolvent evaporation technique using β-cyclodextrin (BCD) as carrier. Characterization of GSBDC was performed by Fourier transform infrared spectroscopy, COSY, differential scanning calorimetry, X-ray diffraction and dynamic light scattering analyses, which were ascribed to the complex formation inside BCD cavity, micronization of drugs and conversion to amorphous state.
Key findings
The complex revealed entrapment of G and S in 3 ± 0.48: 2 ± 0.19 molar ratio and showed more than 3.5 and 10 fold increase in drug release in in vitro and in vivo, respectively. Docking and COSY studies revealed molecular alignment into BCD central cavity that been achieved via hydrogen bonding between certain groups of the ligands (G and S) and the polar heads of BCD. Partial incorporation of the molecular backbone inside inclusion complex suggests superficial contact with the solvent indicating slow steady release kinetics.
Conclusions
This approach of forming inclusion complex with multiple molecules within a single cavity can be a landmark for further studies in drug delivery.

Abstract
OBJECTIVES Cordia (family Boraginaceae) is a genus of deciduous flowering trees or shrubs comprising more than 300 species distributed widely in the tropical regions. The aim of this review was to provide exhaustive scientific information on traditional uses, phytochemistry and pharmacological activities of the 36 important species with medicinal value from the genus Cordia, to divulge prospects for further research on its therapeutic potential. KEY FINDINGS Leaves, fruit, bark and seed of a majority of the species were found to possess abundant ethnomedicinal value, but leaves were found to be used most frequently to treat many ailments such as respiratory disorders, stomach pain, wound, inflammation, myalgia, cough, dysentery and diarrhoea. The phytochemical investigation of 36 species resulted in isolation of 293 chemical constituents from various chemical classes. The crude extracts, fractions, essential oils and pure compounds isolated from various Cordia species were reported to have a varied range of pharmacological activities. SUMMARY Many of the traditional uses of the genus Cordia were supported by the results obtained from pharmacological studies performed using various extracts or pure compounds. More attention should be given to the biological evaluation using pure phytochemicals and to identify the mechanism of actions and exploring this genus for new drug discovery.

Abstract
Leishmaniasis is an epidemic in various countries, and the parasite Leishmania donovani is developing resistance against available drugs. In the present study the antileishmanial action of piperolactam A (PL), isolated after bioactivity guided fractionation from root extracts of Piper betle was accentuated in detail. Activity potentiation was achieved via cyclodextrin complexation. Crude hydro-ethanolic extract (PB) and three fractions obtained from PB and fabricated PL-hydroxypropyl-β-cyclodextrin (HPBCD) nanoparticles were evaluated for antileishmanial activity. Tests were performed against L. donovani wild-type, sodium stibogluconate, paromomycin and field isolated (GE1) resistant strains in axenic amastigote and amastigote in macrophage models. PL-HPBCD complex was characterized and FITC loaded HPBCD nanoparticles were assessed for macrophage internalization in confocal microscopic studies. Isolated and purified PL from most potent, alkaloid rich ethyl acetate fraction of PB showed high level of antileishmanial activities in wild-type (IC50=36 μM), sodium stibogluconate resistant (IC50=103 μM), paromomycin resistant (IC50=91 μM) and field isolated resistant (IC50=72 μM) strains together with cytotoxicity (CC50=900 μM) in mouse peritoneal macrophage cells. Inclusion of PL in HPBCD nanoparticles resulted in 10-fold and 4-10-fold increase in selectivity indexes (CC50/IC50) for wild-type and drug resistant strains, respectively. Drug-carrier interactions were clearly visualized in FT-IR studies. Complete incorporation of PL in HPBCD cavity was ascertained in DSC and XRD analyses. 180nm size stable nanospheres showed macrophage internalization within 1h of incubation. Piperolactam A (PL), a representative of the inchoate skeleton of aristolactam chassis might be the source of safe and affordable antileishmanial agents for the cure of deadly Leishmania infections.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Plant based traditional medicines for birth control has been in practice in rural populations of North-East India, since time immemorial. Fresh rhizome of Drynaria quercifolia (L.) J. Smith is one of the plant parts used traditionally by different ethnic communities in Tripura, India for birth control. The present investigation is aimed to justify the scientific basis in traditional use of Drynaria quercifolia rhizome as anti-fertility agent. MATERIALS AND METHODS Ex-vivo uterotonic activity was done on uterine tissue. Acute toxicity test of the plant extract was carried out in rats of both sexes. The abortifacient and anti-implantation activities of the extract were investigated, in-vivo and estimated the level of different hormones release. RESULTS The result revealed the effectiveness of methanol (87%) and aqueous (68%) extract of the plant on uterotonic activity. The extracts showed relatively non-toxic effect in acute toxicity study. Methanolic extract has shown higher efficacy for both abortifacient (**p<0.01) and anti-implantation performance (**p<0.01) and also effected hormone release level (**p<0.01). CONCLUSION Methanolic extract of Drynaria quercifolia (L.) J. Smith rhizome has been proved to have significant anti-fertility activity.

Abstract
Broussonetia papyrifera leaves (BPL) as a traditional Chinese medicine are also used in livestock feed for stimulating reproduction, adipose tissue and muscle development; however, the mechanism of their action is still unknown. Through estrogen biosynthesis-guided fractionation in human ovarian granulosa-like KGN cells, five new phenolic glycosides, broussoside A–E(1–5), along with fifteen known dietary phenolic compounds, were isolated from the n-butanol extract of BPL, and their structures were elucidated on the basis of NMR spectra analysis and chemical evidence. New compounds 3, 4, 5 and the known compounds 9 and 10 were found to potently inhibit estrogen biosynthesis in KGN cells. In addition, compounds 9, 17, 18, and 20 showed strong antioxidant activity against ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) and DPPH (1, 1′-diphenyl -2-picryl-hydrazyl radical) assays. These findings suggest that BPL may improve meat quality through the regulation of estrogen biosynthesis. Furthermore, they may be useful for the discovery of potential aromatase modulators from natural products. Finally, they could be considered as a new source for natural antioxidants.
