Metallo-Drugs as promising antibacterial agents and their modes of action

Abstract: Antibiotic resistance has been a growing worldwide public health issue. The World Health Organization (WHO) has stated that the search for new antibiotics is slow, while antibiotic resistance is growing. WHO has also declared that antibiotic resistance is one of the top 10 global public health threats facing humanity in the 21st century. Therefore, this review discusses the potential of metal-based drugs as antibacterial agents from the period of the early 2000s to date. The review...

Synthesis of mixed ligand ruthenium (II/III) complexes and their antibacterial evaluation on drug-resistant bacterial organisms

Abstract: The potential antimicrobial properties of a tridentate polypyridyl ligand 4-butoxy-N,N-bis(pyridin-2-ylmethyl)aniline (BUT) 1 and its corresponding mixed ligand ruthenium complexes were investigated on drug-resistant and non-drug-resistant bacterial species. The ligand and its complexes were synthesized and successfully characterized by 1H NMR, UV/Vis, and FTIR spectra; ESI-MS; and magnetic susceptibility. Electronic spectra and magnetic susceptibility of these Ru(II)/(III) complex...

Antibacterial and antioxidant potential of Albizia anthelmintica as a medicinal plant on pathogenic veterinary isolates

Abstract: Albizia anthelmintica is a medicinal plant belonging to the Fabaceae family. It is widely used by smallholder farmers and pastoralists to treat internal parasites in their livestock.This study aimed to determine the antibacterial and antioxidant potential of A. anthelmintica on pathogenic veterinary isolates. 100% hexane (He100), 100% chloroform (Ch100), 100% ethanol (E100), and 70% ethanol (E70) extracts of the roots and barks of A. anthelmintica were tested against four bacterial...

Myrothamnus flabellifolius attenuates streptozotocin-high energy diet-induced type 2 diabetes in male sprague dawley rats

Abstract: Several medicinal plants have anti-diabetic properties and can be considered as an alternative therapy because of their actions which are like those of conventional antidiabetic drugs. In this study, we investigated Myrothamnus flabellifolius (MF) ethanol: water (70:30) extract for its possible anti-diabetic potential in streptozotocin-high energy diet (STZ-HED) induced type 2 diabetes mellitus (T2DM) rats and its possible mechanisms of action. Diabetic rats were divided into MF-50...

A Randomized Trial to Monitor the Efficacy and Effectiveness by QT-NASBA of Artemether-lumefantrine versus Dihydroartemisinin-piperaquine for Treatment and Transmission Control of Uncomplicat

Abstract: Background: Many countries have implemented artemisinin-based combination therapy (ACT) for the first-line treatment of malaria. Although many studies have been performed on efficacy and tolerability of the combination arthemeter-lumefantrine (AL) or dihydroartemisinin-piperaquine (DP), less is known of the effect of these drugs on gametocyte development, which is an important issue in malaria control. Methods and results: In this two-arm randomized controlled trial, 146 children ...

Efficacy of Single-Dose Primaquine With Artemisinin Combination Therapy on Plasmodium falciparum Gametocytes and Transmission: An Individual Patient Meta-Analysis

Abstract: Background. Since the World Health Organization recommended single low-dose (0.25 mg/kg) primaquine (PQ) in combination with artemisinin-based combination therapies (ACTs) in areas of low transmission or artemisinin-resistant Plasmodium falciparum, several single-site studies have been conducted to assess efficacy. Methods. An individual patient meta-analysis to assess gametocytocidal and transmission-blocking efficacy of PQ in combination with different ACTs was conducted. Random ...

The effects of crude propolis, its volatiles andethanolic extracts on the ecto-parasitic mite,Varroa destructorand health of the Africansavannah honey bee,Apis mellifera scutellata

Abstract: Propolis is a hive product composed of biologically active plant resins, and has been shown toenhance individual honey bee (Apis melliferaL.) health. Propolis has also been demonstratedto mitigate, in part, the negative effects caused by the ecto-parasitic miteVarroa destructorand its associated viruses on the health of managed European honey bee colonies.However, its effect on the health status of African honey bees remains largely unknown.Here, we found that the African savannah ...

Synthesis and Anti-Inflammatory Properties of Aminomethyl Derivatives of 2 Naphthol

ABSTRACT The usefulness of non-steroidal anti-inflammatory agents in the management of rheumatoid diseases cannot be over-emphasized. As this disease is characterized by chronic inflammation, it is usual to test compounds for anti-inflammatory activity in animals and then hope that the active ones should be clinically useful as anti-rheumatic drugs, From the literature, non-steroidal anti-inflammatory agents have covered a wide range of chemical structures aryl acetic, aryl-propionic, arylbu...

Anti Inflammatory Activity of the Fatty Seed Extract of Vitellaria Paradoxa (Sapotaceae)

ABSTRACT  Fatty seed extracts of Vitellaria paradoxa (Sapotaceae), an indigenous plant of West Africa is a popular remedy for arthritis and swellings. This study investigated the knowledge, prevalence and pattern of use of the fatty extract also known as shea butter in clinically diagnosed arthritic patients as well as its effects on acute (topical and systemic) and chronic inflammation in rodents. The knowledge, prevalence and pattern of use were determined using pretested questionnaire in ...

Protective Role of Aqueous Leaf Extract of Vernonia Amygdalina Del. (Asteraceae) and Ocimum Gratissimum Linn (Lamiaceae) in Cyclophosphamide Induced Urotoxicity and Myelosuppression

ABSTRACT  Cyclophosphamide (CP) is one of the most potent and widely used alkylating anticancer agents. Urotoxicity and myelosuppression is known as the most prevailing dose-limiting toxicity associated with CP. In the present study, the protective potential of Vernonia amygdalina and Ocimum gratissimum aqueous leaf extracts in CP-induced urotoxicity and myelosupression were evaluated using biochemical and histopathological approaches. Sodium -2-macarptoethane sulfonate (MESNA) was used as a...

Evaluation of the Subacute and Delayed Toxicity of Artemether-Lumefantrine Combination in Rats

ABSTRACT  Despite the reported rapid increase in demand for artemisinin and its derivatives, there is little independent collaboration of the toxicity patterns of artemether-lumefantrine combination besides those documented by the manufacturer in its application for approval. It is however, pertinent to conduct an independent evaluation of the subacute and delayed toxicity of artemether-lumefantrine combination (ALC). In this study, rats in groups I-VI were administered varying concentration...

Evaluation of the Immunomodulatory Activities of the Aqueous Extract and the BetaD-Glucan-Rich Polysaccharide Fraction of Pleurotustuberregium(Pleurotaceae)

ABSTRACT Mushroom cuisines are global delicacies and have been used for decades, not only as food, but mostly for the health benefits which are claimed or scientifically proven. The present study explored the immunomodulatory activities of the hot aqueous extract of a local oyster mushroom, Pleurotustuberregium (Fr.) Singer (Pleurotaceae) (PT) and its β–D-Glucan-Rich Polysaccharide fraction (BGP).The effects of the aqueous extract (PT) and the β–D-Glucan-Rich Polysaccharide fraction (B...
