Bamboo shoot has been used as a treatment for epilepsy in traditional Chinese medicine for generations to treat neuronal disorders such as convulsive, dizziness and headaches. Chemical compounds from Dendrocalamus asper bamboo shoots were purified and identified as major palmitic acids mixed with other minor fatty acids, palmitic acid, 4-hydroxybenzaldehyde, lauric acid, 4-hydroxybenzoic acid and cholesteneone. The response of synthetic 4-hydroxybenzoic acid was tested on Kv1. Readings of treatments with 0. The normalised current of the 4-hba concentrations were compared with potassium channel blockers TEA and 4-AP and all groups showed statistically significant results. This study also showed that time taken for each concentration to affect Kv1. Keywords: Kv1. Many Iranian, African, Indian, and Chinese plants have long been used in folk medicine for the treatment of epilepsy 1 — 5. The antiepileptic constituent may exist in the form of flavonoids 6 , saponins 7 , and triterpenoids 8. However, only a few studies have been done on the potential of plants found in Malaysia for the treatment of epilepsy: Myristica fragrance 9 , Centella asiatica 10 , 11 , Orthosiphon stamineus 12 , Peperomia pellucida 13 , and Acorus calamus Consequently, Chinese traditional medicine TCM suggests that bamboo might be used to prevent epilepsy 5. Chinese also utilise bamboo as a traditional medicine for the treatment of febrile disorders, exogenous diseases, cooling blood, and for homeostasis regulation The most nutritious part comes from its shoot. Bamboo shoots have also been reported to contain phytosterol, high potassium content which helps in maintaining normal blood pressure, low sugar sugar content, high fiber and anti-carcinogenic activity In addition, with more than species worldwide, bamboo shoots and roots are very popular in Asian cuisines such as India, Indonesia and Malaysia Giganteus and D. It constitutes of aromatic benzene ring, hydroxyl substituent and functional derivative that influences the mechanisms, biological activities and properties It is able to pass through blood vessels, blood brain barriers BBB and cerebrospinal fluid CSF due to its low molecular weight As to date, there are not many toxicity studies of this compound on human however, it has been recorded to be slightly irritating to skin and eyes and the maximum bodily intake is estimated to be 0. Other than being used in pharmaceuticals and cosmetic products, 4-hba has been reported to have antifungal, antialgal, antimutagenic, antisickling properties, extrogenic activity and used as trapping agent on hydroxyl radical generation using cerebral ischemia and reperfusion Voltage-gated potassium channels play essential role in restoring the membrane potential and signaling subsequent action potential during neuronal regulation. It is the most abundant and diverse ionic channel identified in the human body with more than 40 types encoded by more than 70 genes and classified into 12 subfamilies Kv1—Kv12 Kv1 family Shaker is mostly distributed around brain, heart, pancreas and kidney. Even though Kv1. Research showed that the contribution of the inactivation components of potassium voltage-gated channel Kv1. The channel consists of 6 transmembrane and one pore which are grouped into voltage-sensor domain S1—S4 , a pore domain or selectivity filter S5—S6 and a re-entrant P-loop region S4—S5 loop 30 , The opening and closing of the selectivity filter is vital in influencing the membrane potential and signaling of inactivation and activation of the channel In this study, we isolated compounds from D. The compounds identified were then studied to see their effects on Kv1. This manuscript reports on one of these compounds: 4-hydroxybenzoic acid identified from D. The flowchart of the experiment methodology is attached as Appendix A. A total of 44 kg of bamboo shoots from Dendrocalamus asper were harvested from Post Brooke village in Gua Musang Kelantan at longitude The chopped bamboo shoots were lyophilised and ground to yield 6 kg dried powder of bamboo shoots. One kg of dried bamboo shoot powder was extracted three times using dichloromethane. The fractions were monitored using thin layer chromatography Merck 1. The fractions containing the same spot were combined. Purification of fractions containing the spot with R f value of 0. Repeated CC on silica gel of fractions containing the spot with R f value of 0. Biocompounds isolated were identified using co-TLC comparing synthetic compounds and purified biocompounds from the extraction process. For 4-hydroxybenzoic acid, TEA, and 4-AP, dilutions were made just prior to the experiment at a ratio of A female frog was anaesthetised for approximately 15 min with 1. In the lateral paramedian area of the lower abdomen, an 8 mm incision was cut into the skin. The layer of the muscles was separated in order to enter the abdominal cavity. Approximately 5 lobes of oocytes tissues were extracted and muscle and skin layers were sutured separately. The digested oocytes were washed with up to 2 L modified OR-2 solution. The data were filtered at Hz and sampled at Hz. For Kv1. The current traces obtained during each perfusion were recorded. The peak amplitude of the potassium current at the beginning and the final amplitude at the terminal of Kv1. The experiment was arranged into control group 0. Each solution was applied for an equilibration period of several seconds before recording was initiated. As fast inactivation is a characteristic of Kv1. Two phenolic compounds, 4-hydroxybenzoic acid and p -hydroxybenzaldehyde, a ketosteroid, cholestenone and common fatty acids; lauric acid and palmitic acid were isolated from the dichloromethane extract of Dendrocalamus asper bamboo shoots. The co-TLC of a standard 4-hydoxybenzoic acid 4-hba with the purified 4-hydroxybenzoic acid also further supported its identification, and it is present as one of the major compounds in chloroform extract of D. Co-Thin Layer Chromatography TLC analysis of crude chloroform extract of Dendrocalamus asper bamboo shoots comparing synthetic 4-hydroxybenzoic acid 4-hba with its isolated biocompound. Single overlapped spot seen on the same R f value proved that the biocompound is 4-hba. Synthetic 4-hydroxybenzoic acid was purchased from Sigma-Aldrich St. The stock solutions were prepared in DMSO at times the targeted concentrations. It gives a final 0. Therefore, perfusion with 0. Enhancement of the Kv1. The figure shows an example of current traces of the oocyte when perfused with 0. Inset plotted graphs represent the highest current value in bar graph. The effects of five different doses of 4-hydroxybenzoic acid on Kv1. The perfused solution was turned off once the current trace returned to the equilibrated level resting potential , which usually takes about 3 min. ND96 was continued to perfuse the system and bath the oocytes for another several minutes to ensure that 4-hba has been completely washed out before the addition of blockers. Two blockers of potassium channel, In all groups, the addition of The largest values of the ratio were selected from 1—5 min after the application of the two blockers, and the highest response mostly came from the 5th min of blockers application. These responses obtained at the 5th min of blockers application were compared with the responses from the 5th min of 4-hydroxybenzoic acid groups. It showed a tendency of the faster effect of 4-hydroxybenzoic acid on the Kv1. The enhancement effect disappeared after several minutes. This could be observed from Figure 3D of the time of the maximum effects of the 4-hydroxybenzoic acid on Kv1. The classic Kv1. The Kv1. Therefore, the component of Kv1. The parameters of our Kv1. The index of the opening of Kv1. We hypothesise that the enhancement of the Kv1. According to references, the contribution of the block effect of TEA is much less than that of 4-AP 37 , It showed a dose response of the enhancement effect of Kv1. In addition, the time of maximum effect of 4-hydroxybenzoic acid has a tendency to be faster in higher dosages except for the effect of 2. The inactivation of Kv1. However, these inactivation mechanisms have been shown to be affected by many factors such as pH, extracellular K ion concentrations and oxidation. Rapid N-type inactivation is important in developing the C-type, which is hypothesised to involve the selectivity filter, conformational changes, mutations of the pore, quinidine binding 39 , intracellular pore closure 47 , and osmotic pressure According to Claydon et al. In addition, the inactivation mechanisms of Kv1. The existence of cysteine 53 and methionine 54 , 55 near the terminals could disrupt the inactivation signaling at the pore, thus enhancing the activation of the channel and causing prolonged depolarisation. This effect can be reversed with anti-oxidation. As 4-hba is a low acid phenol with a pk a of 4. All phenols are classified as anti-oxidant at varying degrees depending on their chemical structure and functional group. Though not as strong as salicylic acid, 4-hba exhibits a stronger anti-oxidation property compared to its other functional group 56 , Therefore, due to its anti-oxidative property, 4-hba can interfere with the oxidation of the cysteine and methionine residues at the channel pore and influence the development of N and C-type inactivations. Figure 3A shows that the dose response curve has a Hill slope of 0. However, the values become significant again at 1. As the endogenous Cl - channel is the most abundant 59 , 60 and is important for repolarisation, the activation of the channel will help to lower the membrane potential. Hence, it is able to produce significant values even at concentrations exceeding the IC 50 value. Although the effective window of 4-hydroxybenzoic acid on Kv1. This study demonstrated that 4-hydroxybenzoic acid identified in Dendrocalamus asper bamboo shoots could enhance the activities of Kv1. These findings provided us new leads to further identify and examine other compounds found in D. This is the first report on 4-hba identified through the extraction of D. We await the results of effects of other biocompounds from D. As a library, NLM provides access to scientific literature. Find articles by Jingli Zhang. Find articles by Fatin H Mohamad.
