Urinary tract infections (UTIs) in the United States result in more than 7 million hospital visits per year. Uropathogenic E. coli (UPEC) is responsible for more than 80% of UTIs. Although antibiotics are the drug of choice to control UTIs, their repeated use has resulted in the emergence of antibiotic resistant UPEC. Thus, there is a need for effective alternate strategies to control UPEC infections. This study investigated the efficacy of trans-cinnamaldehye (TC), a food-grade molecule present in cinnamon, in reducing UPEC colonization and pathogenesis in the lower UTI...

Using ultrasonic technology, trans-cinnamaldehyde as a natural antibacterial compound was used to prepare nano size emulsions to increase its bioavailability and therefore bactericidal action. Nanoemulsions containing trans-cinnamaldehyde as an active agent and 1,8 cineol as co additive oil (Ostwald ripening inhibitor) were formulated using probe sonicator. Three different determining factors, namely time of sonication, surfactant to oil ratio and type of emulsifier (Tween 80 and Tween 20) were investigated to enhance the stability profile...

The regiospecific synthesis of 1H-indene-2-carbaldehyde derivatives was achieved through transition-metal-free, reductive cyclisation of ortho-formyl trans-cinnamaldehydes with Hantzsch ester in the presence of an aminocatalyst. In particular, cycloolefin isomerisation of the resulting products could be inhibited efficiently by the introduction of a sterically demanding stereo-defined aminocatalyst.

Parasitic gastrointestinal nematodes (GIN) of livestock are increasingly developing resistance to synthetic nematocidal drugs. Moreover, the use of nematocides can induce ecotoxicity by affecting free-living nematodes. Condensed tannins (CT) are a structurally diverse group of bioactive plant compounds possessing anthelmintic activity against GIN. We investigated the relationship between the chemical structure of contrasting, purified CT and nematocidal effects using Caenorhabditis elegans. We also explored whether the nematocidal activity of CT could synergize with trans-cinnamaldehyde (CIN)...

Inhalation of scent compounds with phenylpropanoidal structures, such as trans-cinnamaldehyde, is expected to increase the appetite. The scent of curry powder is well known for its appetite-enhancing effect on humans. In this work, we show that the appetite of mice after inhalation of curry powder essential oil or benzylacetone showed a similar increase. The components of curry oil, trans-cinnamaldehyde, trans-anethole, and eugenol, each showed appetite-enhancing effects; therefore, these three scent compounds may be the active compounds in curry powder oil...

Juvenile Hormone III is of great concern due to negative effects on major developmental and reproductive maturation in insect pests. Thus, the elucidation of enzymes involved JH III biosynthetic pathway has become increasing important in recent years. One of the enzymes in the JH III biosynthetic pathway that remains to be isolated and characterized is farnesal dehydrogenase, an enzyme responsible to catalyze the oxidation of farnesal into farnesoic acid. A novel NAD+-farnesal dehydrogenase of Polygonum minus was purified (315-fold) to apparent homogeneity in five chromatographic steps...

Ischemia stroke is the major cause of mortality and permanent neurological disability with little definitive therapeutic options. This cerebral ischemic injury leads to the oxidative stress and eventually cell death. We hypothesized that treatment of this condition with the trans-cinnamaldehyde(TC) could protect cells from ischemic and reperfusion injury. Oxygen and glucose deprivation/reperfusion (OGD/R) was used as an in vitro model of hypoxic ischemic injury in present study. MTT was used to evaluate the protective effects of TC...

Perla Ramesh, Tadikamalla P Rao
A protecting-group-free total synthesis of (+)-goniodiol (1), (6S,7S,8S)-goniodiol (2), (-)-parvistone D (4), and (+)-parvistone E (6) was efficiently achieved in five steps from commercially available trans-cinnamaldehyde with high overall yields (72-75%). The synthesis strategy was inspired from the proposed biosynthesis pathway of styryllactones. Key transformations of the strategy include a one-pot conversion of goniothalamin oxide to goniodiol or 9-deoxygoniopypyrone in aqueous media, stereoselective epoxidation, ring-closing metathesis, and stereoselective Maruoka allylation...

The chitosan-based coating with antimicrobial agent has been developed recently to control the decay of fruits. However, its fresh keeping and antimicrobial mechanism is still not very clear. The preservation mechanism of chitosan coating with cinnamon oil for fruits storage is investigated in this paper. Results in the atomic force microscopy sensor images show that many micropores exist in the chitosan coating film. The roughness of coating film is affected by the concentration of chitosan. The antifungal activity of cinnamon oil should be mainly due to its main consistent trans-cinnamaldehyde, which is proportional to the trans-cinnamaldehyde concentration and improves with increasing the attachment time of oil...

UNLABELLED: The transient receptor potential cation channel subfamily M 8 (TRPM8) agonist L-menthol has been used traditionally for its topical counterirritant properties. Although the use of topical L-menthol for pain is casuistically established, evidence regarding its efficacy is negligible. This study aimed to characterize the effect of L-menthol as a counterirritant on cutaneous pain and hyperalgesia provoked by topical application of the transient receptor potential cation channel, subfamily A, member 1 (TRPA1) agonist trans-cinnamaldehyde (CA)...

Benzylacetone has appetite-enhancing and locomotor-reducing effects. The effective doses for these two outcomes overlap, and the weight gain of mice exposed to benzylacetone is caused by both appetite-enhancement and a reduction in locomotor activity. The appetite-enhancing effects of trans-cinnamaldehyde and benzylacetone have been reported previously. In this study, these appetite-enhancing effects were seen in mice after short-term, high-dose exposure.

A frequent empirical observation is that cold-induced counter-irritation may attenuate itch. The aim of this randomized, single-blinded, exploratory study was to evaluate the counter-irritation effects of cold-stimulation and topical application of transient receptor potential TRPA1/M8-agonists (trans-cinnamaldehyde/L-menthol, respectively), on histamine-induced itch, wheal and neurogenic inflammation in 13 healthy volunteers. Histamine 1% was applied to the volar forearms using skin prick-testing lancets. Recorded outcome-parameters were itch intensity, wheal reactions and neurogenic inflammation (measured by laser-speckle perfusion-imaging)...

Trans-cinnamaldehyde (TCA), an essential oil in cinnamon powder, may have beneficial effects as a treatment for stroke which is the second leading cause of death worldwide. Post-ischemic inflammation induces neuronal cell damage after stroke, and activation of microglia, in particular, has been thought as the main contributor of proinflammatory and neurotoxic factors. The purpose of this study was to investigate the neuroprotective effects of TCA in an animal model of ischemia/reperfusion (I/R)-induced brain injury and the neuroprotective mechanism was verified in LPS-induced inflammation of BV-2 microglial cells...
