Prostate cancer is the second most frequently occurring cancer diagnosed among males. Recent preclinical evidence implicates cannabinoids as powerful regulators of cell growth and differentiation. In this review, we focused on studies that demonstrated anticancer effects of cannabinoids and their possible mechanisms of action in prostate cancer. Besides the palliative effects of cannabinoids, research from the past two decades has demonstrated their promising potential as antitumor agents in a wide variety of cancers. This analysis may provide pharmacological insights into the selection of specific cannabinoids for the development of antitumor drugs for the treatment of prostate cancer.
Magnesium hydroxide (Mg(OH)2) is hailed as a cheap and
biocompatible material with antimicrobial potential; however, research
aimed at instilling additional properties and functionality to this
material is scarce. In this work, we synthesized novel, fluorescent
magnesium hydroxide nanosheets (Mg(OH)2-NS) with a morphology
that closely resembles that of graphene oxide. These multifunctional
nanosheets were employed as a potent antimicrobial agent against several
medically relevant bacterial and fungal species, particularly on solid
surfaces. Their strong fluorescence signature correlates to their
hydroxide makeup and can therefore be used to assess their degradation
and functional antimicrobial capacity. Furthermore, their pH-responsive
change in fluorescence can potentially act as a pH probe for wound
acidification, which is characteristic of healthy wound healing. These
fluorescent antimicrobial nanosheets were stably integrated into biocompatible
electrospun fibers and agarose gels to add functionality to the material.
This reinforces the suitability of the material to be used as antimicrobial
bandages and gels. The biocompatibility of the Mg(OH)2-NS
for topical medical applications was supported by its noncytotoxic
action on human keratinocyte (HaCaT) cells.
Melanoma is deadly, physically impairing, and has ongoing treatment deficiencies. Current treatment regimens include surgery, targeted kinase inhibitors, immunotherapy, and combined approaches. Each of these treatments face pitfalls, with diminutive five-year survival in patients with advanced metastatic invasion of lymph and secondary organ tissues. Polyphenolic compounds, including cannabinoids, terpenoids, and flavonoids; both natural and synthetic, have emerging evidence of nutraceutical, cosmetic and pharmacological potential, including specific anti-cancer, anti-inflammatory, and palliative utility. Cannabis sativa is a wellspring of medicinal compounds whose direct and adjunctive application may offer considerable relief for melanoma suffers worldwide. This review aims to address the diverse applications of C. sativa’s biocompounds in the scope of melanoma and suggest it as a strong candidate for ongoing pharmacological evaluation.
Crosslinking of hydroxypropyl methyl cellulose (HPMC) and acrylic acid (AAc) was carried out at various compositions to develop a high-solid matrix with variable glass transition properties. The matrix was synthesized by the copolymerisation of two monomers, AAc and N,N′-methylenebisacrylamide (MBA) and their grafting onto HMPC. Potassium persulfate (K2S2O8) was used to initiate the free radical polymerization reaction and tetramethylethylenediamine (TEMED) to accelerate radical polymerisation. Structural properties of the network were investigated with Fourier transform infrared spectroscopy (FTIR), Xray diffraction (XRD), modulated differential scanning calorimetry (MDSC), small-deformation dynamic oscillation in-shear, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The results show the formation of a cohesive macromolecular entity that is highly amorphous. There is a considerable manipulation of the rheological and calorimetric glass transition temperatures as a function of the amount of added acrylic acid, which is followed upon heating by an extensive rubbery plateau. Complementary TGA work demonstrates that the initial composition of all the HPMC-AAc networks is maintained up to 200 °C, an outcome that bodes well for applications of targeted bioactive compound delivery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
