Abstract
The Enterobacteriaceae family is recognized as a primary group of Gram-negative pathogens responsible for foodborne illnesses and is frequently associated with antibiotic resistance. The present study explores the natural-based compound trans-cinnamaldehyde (TC) against drug-resistant Enterobacteriaceae and its synergism with gentamicin (GEN) to address this issue. The research employs three strains of Escherichia coli, Klebsiella pneumoniae, and Enterobacter cloacae, previously isolated from shrimp. The antibacterial activity was evaluated by the disk diffusion method, microdilution test, kinetics of growth, and time-kill curve. In addition, the synergistic effect between TC/GEN was investigated by checkerboard assay. All strains showed sensitivity to TC with an inhibition zone diameter > 35 mm. The TC showed inhibitory and bactericidal action in the most tested bacteria around 625 μg/mL. Sub-inhibitory amounts (1/2 and 1/4 MIC) of TC interfered with the growth kinetics by lag phase extension and decreased the log phase. Time-kill curves show a reduction of viable cells after the first hour of TC treatment at bactericidal concentrations. The synergistic effect between TC/GEN was observed for E. coli and E. cloacae strains with FICi ranging from 0.15 to 0.50. These findings, therefore, suggest TC as a promising alternative in the fight against drug-resistant Enterobacteriaceae that can cause foodborne illnesses.

Abstract
Cancer is a global health challenge with high morbidity and mortality rates. However, conventional cancer treatment methods often have severe side effects and limited success rates. In the last decade, extensive research has been conducted to develop safe, and efficient alternative treatments that do not have the limitations of existing anticancer medicines. Plant-derived compounds have shown promise in cancer treatment for their anti-carcinogenic and anti-proliferative properties. Rosmarinic acid (RA) and carnosic acid (CA) are potent polyphenolic compounds found in rosemary (Rosmarinus officinalis) extract. They have been extensively studied for their biological properties, which include anti-diabetic, anti-inflammatory, antioxidant, and anticancer activities. In addition, RA and CA have demonstrated effective anti-proliferative properties against various cancers, making them promising targets for extensive research to develop candidate or leading compounds for cancer treatment. This review discusses and summarizes the anti-tumor effect of RA and CA against various cancers and highlights the involved biochemical and mechanistic pathways.

Abstract
BACKGROUND Transient receptor potential ankyrin-1 (TRPA1) channels expressed in the central terminal of dorsal root ganglion neurons in the spinal substantia gelatinosa (SG) play a role in modulating nociceptive transmission. Although plant-derived compounds exhibiting antinociception (such as eugenol, carvacrol and thymol) activate TRPA1 channels to enhance spontaneous excitatory transmission while hyperpolarizing membranes in SG neurons without TRPA1 activation, specific chemical moieties involved in synaptic modulation are unknown. METHODS We examined the effects of other plant-derived compounds (guaiacol, vanillin, vanillic acid and p-cymene) on holding current and spontaneous excitatory transmission at -70 mV by applying the whole-cell patch-clamp technique to SG neurons in adult rat spinal cord slices. RESULTS None of the compounds affected the frequency or amplitude of spontaneous excitatory postsynaptic current. Guaiacol and vanillic acid had no effect on holding currents, while vanillin and p-cymene produced an inward and outward current, respectively, in some neurons tested. Synaptic modulation was also observed within the same neuron as the activities of eugenol, carvacrol, thymol, and the chemically-related plant-derived compound zingerone occurred. CONCLUSION A substituted group in eugenol and zingerone, but not in guaiacol, vanillin or vanillic acid, as well as an OH bound to the benzene ring of carvacrol and thymol, but not p-cymene, play a role in producing outward current and TRPA1 activation. Thus, the binding of such chemical moeties to the benzene ring of plant-derived compounds appears necessary to modulate nociceptive transmission in the SG. This information provides insight for the development of new analgesics based on plant-derived compounds.

Anti-cancer activity of asiatic acid against human cholangiocarcinoma cells through inhibition of proliferation and induction of apoptosis. Cell Mol Biol (Noisy-le-grand) 2018; 64:28-33.

Abstract
Plant-derived anti-cancer agents have been of considerable interest due to their promising effectiveness with low side effects. Asiatic acid, the main constituent of the medicinal plant Centella asiatica (L.) Urban, has a wide range of biological properties such as antioxidant, anti-inflammatory and anti-cancer activities. Cholangiocarcinoma (CCA), which is a malignant tumor of bile duct epithelium, is one of the leading cancers in Southeast Asia, notably the northeast of Thailand where the liver fluke, Opisthorchis viverrini predominates. Many in vitro and in vivo studies have provided evidence supporting that oxidative stress induced by chronic inflammation is involved in CCA genesis with aggressive clinical outcomes. This study was performed to evaluate the cytotoxic effects of asiatic acid on two human CCA cell lines (KKU-156 and KKU-213). Cell viability was determined by a sulforhodamine B (SRB) assay. Morphological changes of the cells were observed by microscopy. Cell apoptosis was detected by flow cytometry using annexin V and propidium iodide (PI) staining. Messenger RNA (mRNA) expression levels of BAX, BCL2 and Survivin/BIRC5 were analyzed by real-time polymerase chain reaction (PCR). It was found that asiatic acid efficiently suppressed CCA cellular viability via induction of apoptosis. In addition, the occurrence of asiatic acid-induced apoptosis was confirmed by microscopic observation of apoptotic vesicles, down-regulation of anti-apoptotic genes (BCL2 and Survivin/BIRC5) and increased early and late apoptotic cells. Our results showed the chemotherapeutic activities of asiatic acid, suggesting the anti-cancer properties of this compound should be clinically assessed and its supplementation may lead to an improvement of survival of CCA patients.
