OBJECTIVES: Despite its broad spectrum, conventional amphotericin B (AB) is associated with serious adverse events. Lipid-based formulations may offer safer options. We aimed to synthesize the evidence of efficacy and safety of AB formulations. METHODS: We performed a systematic review and network meta-analysis (NMA) to compare all available formulations: conventional AB; lipid complex or ABLC; colloidal dispersion or ABCD; liposomal or LAB; AB in Intralipid. Randomized controlled trials were searched in four databases...

OBJECTIVES: Bacterial pneumonia is a common cause of death worldwide. Tea tree oil (TTO) is a potent antimicrobial natural product, which is formulated in dry powder inhalers (DPIs) for the treatment of fungal and bacterial pneumonia. METHODS: Tea tree oil-β-cyclodextrin inclusion complexes (TTO-β-CD) were prepared and characterized. Aerodynamic properties of TTO-β-CD powders were measured. The rat models of fungal (Candida albicans) and bacterial (Acinetobacter baumannii) pneumonia were prepared...

OBJECTIVES: Mitotane is the reference drug for the adrenocortical carcinoma treatment; its pharmacological activity seems to depend on drug transformation in two active metabolites: o,p'-DDE (dichlorodiphenylethene) and o,p'-DDA (dichlorodiphenylacetate). Mitotane and metabolites are lipophilic agents; thus, they tend to accumulate into adipose tissues (white and brown), which change their prevalence seasonally. Aim of the work was to evaluate mitotane and metabolites plasma levels variation over the year, in adrenocortical cancer patients treated with Lysodren(®) for at least 6 months...

OBJECTIVE: This study was aimed to investigate the potential of formulated valproic acid-encapsulated nanoemulsion (VANE) to improve the brain bioavailability of valproic acid (VPA). METHODS: Valproic acid-encapsulated nanoemulsions were formulated and physically characterised (osmolarity, viscosity, drug content, drug encapsulation efficiency). Further investigations were also conducted to estimate the drug release, cytotoxic profile, in-vitro blood-brain barrier (BBB) permeability, pharmacokinetic parameter and the concentration of VPA and VANE in blood and brain...

OBJECTIVES: This study aimed to prepare a furosemide-loaded sustained release cellulose nanofibre (CNF)-based nanofoams with buoyancy. METHODS: Dry foams consisting of CNF and the model drug furosemide at concentrations of 21% and 50% (w/w) have been prepared by simply foaming a CNF-drug suspension followed by drying. The resulting foams were characterized towards their morphology, solid state properties and dissolution kinetics. KEY FINDINGS: Solid state analysis of the resulting drug-loaded foams revealed that the drug was present as an amorphous sodium furosemide salt and in form of furosemide form I crystals embedded in the CNF foam cell walls...

OBJECTIVES: The large number of publications about Amaryllidaceae alkaloids reflects the abundance and variety in biological activity of these alkaloids. An in-silico approach was implemented in this work to rationalize the individual alkaloids to molecular biological activity. METHODS: A database was generated containing 313 Amaryllidaceae alkaloids which were then subjected to in-silico-validated structure-based virtual screening using extra precision (XP) approach of Glide docking program...

OBJECTIVES: This study was carried out to investigate the impact of various isolated phytochemical components present in the Wattakaka volubilis leaves for the growth and proliferation of human osteoblast like cells (MG63). KEY FINDINGS: Ethyl acetate was found to be the best solvent for potential extraction of phytocompounds. Further, the MTT assay was carried out to deduce the viability of 44 isolated phytochemicals. Ten phytochemical fractions found to increase the cell growth were subjected to statistical tool namely Plackett-Burman and Central composite design to screen the optimum phytochemical fraction and its dosage...

OBJECTIVES: To study the functional consequences of the human and rat forms of OCT2 in the presence of phenothiazines. METHODS: MDCK cells expressing human or rat OCT2 were established, and MPP+ transport was determined by uptake assays. Concentration dependency was studied for the stimulatory/inhibitory effects of phenothiazines on MPP+ transport. KEY FINDINGS: Among the 11 phenothiazines examined, the majority were found to have comparable effects on transporter function between the orthologous forms, while three phenothiazines, particularly mesoridazine, had complex impacts on transporter function...

Shanshan Liu, Paul C Ho
OBJECTIVES: Scutellarin (SCU) is a traditional Chinese medicine used for the treatment of ischaemic cerebrovascular disease, but its clinic applications have been limited due to its poor water solubility, poor bioavailability and short half-life. In comparison with the conventional oral and intravenous administration, nasal administration may help targeting the drug more directly to brain. Thus, we proposed to employ a novel SCU-loaded HP-β-CD/chitosan nanoparticles (CD/CS-SCU-NPs) to deliver SCU to brain through the nasal route...

OBJECTIVES: Transdifferentiation is defined as the conversion of one cell type to another and is an ever-expanding field with a growing number of cells found to be capable of such a process. To date, the fact remains that there are limited treatment options for fracture healing, osteoporosis and bone repair post-destruction by bone tumours. Hence, this review focuses on the transdifferentiation of myoblast to osteoblast as a means to further understand the transdifferentiation process and to investigate a potential therapeutic option if successful...

OBJECTIVE: This study was implemented to evaluate the effect of genistein and propofol on intracranial tumour model. METHODS: Male Fischer 344 rats were subjected to intracranial implantation of 9L gliosarcoma cells. Genistein (100 or 200 mg/kg b.wt) was administered orally regularly from 3rd day after implantation to 25th day. Propofol (20 mg/kg; i.p.) was administered once every 5 days till 25th day and was administered 2 h after genistein. KEY FINDINGS: Human gliosarcoma cells (U251) exposed to genistein (12...

OBJECTIVES: This study reports global and local monoclonal antibody (mAb)-excipient interactions and the resulting thermodynamic and stabilization effects. METHODS: Molecular dynamics simulations are applied to quantify the interactions of key excipients (sucrose, sorbitol, arginine, citrate, histidine and NaCl) used in the formulations of three mAbs. The dynamic surface properties of the mAbs and preferential interaction coefficients for the excipients based on validated potential parameters are computed, in addition to the spatial aggregation propensity...

Akash Patil, Soumyajit Majumdar
OBJECTIVES: Echinocandins are the newest addition of the last decade to the antifungal armamentarium, which, owing to their unique mechanism of action, selectively target the fungal cells without affecting mammalian cells. Since the time of their introduction, they have come to occupy an important niche in the antifungal pharmacotherapy, due to their efficacy, safety, tolerability and favourable pharmacokinetic profiles. This review deals with the varying facets of echinocandins such as their chemistry, in-vitro and in-vivo evaluations, clinical utility and indications, pharmacokinetic and pharmacodynamic profiles, and pharmacoeconomic considerations...
