What is triptolide used for?
Triptolide is a principal bioactive ingredient of the Tripterygium wilfordii Hook F, which has been used in traditional Chinese medicine for treating autoimmune and inflammatory diseases for centuries ( Brinker et al., 2007 ). In addition to its immunosuppressive, antifertility, antineoplastic and antiinflammatory properties, triptolide has attracted extensive research interest in its antitumor effects. Previous studies have shown that triptolide is highly effective against a variety of cancer types, including melanoma, breast cancer, bladder cancer, and gastric cancer ( Chen, 2001; Ding et al., 2014; Liu, 2011; Yang et al., 2003 ). Mei et al. (2003) showed that SLNs prepared for transdermal delivery increased triptolide penetration into the skin and its antiinflammatory activity. This strategy improves the drug’s bioavailability at the site of action, reduces the required dose, and reduces dose-dependent side effects like irritation and stinging ( Nair et al., 2010 ).
How does polymorphism affect SLNs?
Polymorphism is an important physical stability process that affects stability in solid dosage forms because various polymorphs have different thermodynamic properties such as melting points, X-ray diffraction, and solubility [111]. The main polymorphs in glycerides are the α, β′, and β forms; the α form can quickly transform to a form with better chain packing such as the β′ form. The transition of triglycerides of liquid melt from α to β via the β′ was the pathway to the optimum packing form of the molecules. During storage at elevated temperatures, this unstable form gradually transforms toward the most stable form while losing the initial spherical surface structure [116]. Polymorphism influenced the nanoparticle content, and the presence of oil allowed for higher drug loads [49,50]. Jenning showed that the in vitro results on skin showed that when water evaporates, it leads to solid modification changes of SLN dispersion causing drugs to be expelled from the lipids resulting in an increase in penetration of drug into the skin [117]. The problem of lipid modification is not always solved with assignments to α, β, or β′ form. The complexity increases as a result of many subspecies and the interactions of the lipid with the emulsifiers. Westesen's group demonstrated that the decisive factor for the physical properties of SLNs is the particle size [118].
What are the lipids in SLNs?
Some phytochemicals that have been encapsulated within SLNs using various carrier lipids with different melting points include curcuminoids in trimyristin, tristearin, and glyceryl monosterate as solid lipids and MCT as liquid lipid (Nayak et al., 2010 ), curcuminoids in glyceryl monostearate and stearic acid ( Tiyaboonchai et al., 2007 ), curcuminoids in glyceryl behenate ( Kakkar et al., 2011 ), β-carotene in canola stearin ( Malaki Nik et al., 2012 ), β-carotene in tripalmitin and MCT ( Helgason et al., 2009 ), β-carotene and α-tocopherol in stearyl ferulate or stearic acid ( Trombino et al., 2009 ), and quercetin in glyceryl monostearate ( Li et al., 2009 ). These studies suggested that the water solubility and bioavailability of core materials as well as the stability against degradation can be improved by using their inclusion in SLNs. The results also showed that the encapsulation efficiency and capacity, stability, size, and properties of SLNs can be affected by various parameters, including type and concentration of emulsifier, type of carrier lipid, the ratio of lipid to core material, temperature, and homogenization pressure ( Lee and Wong, 2014 ).
Is quercetin a phytochemical?
Quercetin, a phytochemical, has attractive properties that lend to its potential use in the treatment of neurological and cardiovascular diseases and cancer therapy and has further advanced to clinical trial evaluation; however, the poor water solubility has limited its further commercialisation ( Li et al., 2009; Braithwaite et al., 2014 ). Li et al. (2009) showed through animal studies that the bioavailability and absorption of quercetin were enhanced significantly when it was encapsulated in SLNs stabilized with Tween 80 and lecithin. The significant enhanced absorption shown in the study was suggested to be due to several factors: (1) the size of SLN being 20–500 nm allows uptake into the intestine; (2) the surface properties of SLN increase the permeability through the intestinal membrane or improve the affinity or adhesion of SLN to the GIT wall membrane; and (3) quercetin is protected from the degradation during the absorption process ( Lee and Wong, 2014 ).
Does nutmeg oil kill gram positive bacteria?
Various extracts and the essential oil of nutmeg seeds have presented strong antimicrobial activity against gram-positive and gram-negative bacteria, as well as a variety of fungi. Takikawa et al. (2002) reported antimicrobial activity of ethanolic extract of nutmeg seeds against entero-hemorrhagic E. coli O157, which was found to be highly sensitive to β-pinene. Narasimhan and Dhake (2006) reported potent antibacterial activity of chloroform extract of nutmeg seeds against both gram-positive and gram-negative bacteria. They found trimyristin and myristic acid to be the chief antibacterial principles isolated from nutmeg seeds. Cho et al. (2007) isolated three lignans (erythro-austrobailignan-6, meso-dihydroguaiaretic acid, and nectandrin-B) from the methanolic extract of nutmeg seeds, which were reported to have antifungal activity. These three lignans were found to suppress the development of rice blast and wheat leaf rust. Some important antimicrobial compounds reported in nutmeg seeds are α-pinene, β-pinene, p-cymene, carvacrol, and β-caryophyllene, ( Dorman & Deans, 2004) ( Figure 98.5 ). Many plant phenolics have been reported to possess antimicrobial activity. β-Caryophyllene has been reported to have anti-inflammatory and antifungal activities ( Sabulal et al., 2006 ). α-Pinene and β-pinene (pinene-type monoterpene hydrocarbons) have been reported to have antimicrobial activity ( Dorman & Deans, 2000 ), and are supposed to be involved in membrane disruption by the lipophilic compounds. Another important component for antimicrobial activity could be carvacrol. The mode of action of carvacrol on bacteria is similar to that of other phenolic compounds, and occurs via membrane damage, resulting in an increase in membrane permeability to protons and potassium ions, depletion of the intracellular ATP pool, and disruption of the proton-motive force. p-Cymene could also be an important component, because it is a precursor of carvacrol. It has been reported that p-cymene shows weak antibacterial activity when used alone, but works synergistically with carvacrol in expanding the membrane, which in turn causes destabilization of the membrane ( Ultee et al., 2002 ). It has been suggested that antimicrobial activity could be attributed to both major and minor components; it is possible that the antimicrobial activity of major components is regulated by some other minor components, as well as these minor components being able to interact with other components to exert antimicrobial activity ( Bounatirou et al., 2007 ).
