Antihepatotoxic activity of debelalactone, a new oxirano-furanocoumarin from Phyllanthus debilis.

27 Jul 2009-Journal of Asian Natural Products Research (Taylor & Francis)-Vol. 11, Iss: 8, pp 687-692
TL;DR: Debelalactone exhibited a significant antihepatotoxic activity by reducing the elevated levels of serum enzymes such as serum glutamate oxaloacetate transaminase (SGOT) and alkaline phosphatase (ALP) and increasing the total protein levels against CCl4-induced toxicity in Wistar rats.

TL;DR: In the current rush to use antibodies with tissue sections, much work of poor quality is being carried out, and this volume should be a considerable help to those in difficulty.
Abstract: biologists, and biologists, with a strong contribution from Oxford. The first chapter is a comprehensive review (by Brandtzaeg) of tissue preparation methods and particularly fixation; and each of the subsequent chapters is devoted to one technique. Those covered include double-label immunofluorescence (Pryzwansky); the unlabelled antibody peroxidase-antiperoxidase (PAP) method (Burns); the protein A-gold technique (Roth); double immunoenzymatic labelling (Mason and Woolston); and the use of proteolytic enzymes (Finley and Petrusz). Each chapter has a wide range of relevant references, and methods suitable for light and electron microscopy are discussed. Although much of the text consists of methodological detail, it is still very readable. In the current rush to use antibodies with tissue sections, much work of poor quality is being carried out, and this volume should be a considerable help to those in difficulty. Even the experienced investigator will learn a great deal from it. It is a wellproduced book, with good illustrations, which fills a gap in the literature. It is highly recommended.

TL;DR: The ethnopharmacological, phytochemical, and pharmacological studies of Phyllanthus over the past few decades are discussed, including the researches of their remarkable antiviral, antioxidant, antidiabetic, and anticancer activities.
Abstract: The plants of the genus Phyllanthus (Euphorbiaceae) have been used as traditional medicinal materials for a long time in China, India, Brazil, and the Southeast Asian countries. They can be used for the treatment of digestive disease, jaundice, and renal calculus. This review discusses the ethnopharmacological, phytochemical, and pharmacological studies of Phyllanthus over the past few decades. More than 510 compounds have been isolated, the majority of which are lignins, triterpenoids, flavonoids, and tannins. The researches of their remarkable antiviral, antioxidant, antidiabetic, and anticancer activities have become hot topics. More pharmacological screenings and phytochemical investigations are required to support the traditional uses and develop leading compounds.

TL;DR: This review is an attempt to present an overview of the existing studies on pharmacognostics, phytochemistry, species identification, and genetic diversity of Phyllanthus herbs to highlight areas where further research is needed and draw attention towards extending similar studies in underutilized but potentially important herbs.
Abstract: The genus Phyllanthus consists of more than 1000 species, of which many are used as traditional medicines. The plant extracts have been used since ancient times, for treating hypertension, diabetes, hepatic, urinary, and sexual disorders, and other common ailments. Modern day scientific investigations have now confirmed pharmacognostic properties of Phyllanthus herbs. The phytochemicals attributing these medicinal properties have been identified in many of the Phyllanthus herbs. The morphologically similar herbs of Phyllanthus grow together and admixture of species during collection for manufacture of herbal medicines is quite common. Hence, along with pharmacognostic and phytochemical studies, appropriate protocols for correct identification of species are also important. As the use of these herbs as green medicines is becoming more popular, it is imperative to assess its genetic diversity and phylogenetic relatedness for future conservation strategies. This review is an attempt to present an overview of the existing studies on pharmacognostics, phytochemistry, species identification, and genetic diversity of Phyllanthus herbs and consequently (i) highlight areas where further research is needed and (ii) draw attention towards extending similar studies in underutilized but potentially important herbs such as P. maderaspatensis, P. kozhikodianus, P. rheedii, P. scabrifolius, and P. rotundifolius.

TL;DR: The study of antihepatotoxic activity and molecular prediction of compounds isolated from Phyllanthus debelis shows that compound V debelolactone has good drug likeness score with no violations & good bioactivity score as compared to silibinin which is potent hepatoprotective drug.
Abstract: Objective Present communication deals with the study of antihepatotoxic activity and molecular prediction of compounds isolated from Phyllanthus debelis in order to search lead compound. Methods Five compounds from the whole plant of P. debelis were subjected to molecular properties prediction and drug-likeness by Lipinski rule of five & Molinspiration software. Results All the compounds were found in compliance with Lipinski ‘Rule of Five’ except the Milog P valve of compound No. I-IV were found above five means these compounds have less permeability across the cell membrane. The Milog P valve of Compound No V & standard compound silibinin VI were found below five, suggest that the molecules have good permeability across the cell membrane. In respect of TPSA, all the compounds were within the limit i.e. 160 A. The bioactivity score was also calculated for GPCR ligand, ion channel modulator, kinase inhibitor, nuclear receptor ligand. All the compound showed activity through enzyme inhibition. Conclusions Our study shows that compound V debelolactone has good drug likeness score with no violations & good bioactivity score as compared to silibinin which is potent hepatoprotective drug. So compound V debelolactone can be a lead compound with hepatoprotective activity from Phyllanthus debelis .

TL;DR: The main purpose of the present paper is to give the exact tables for making two-sided comparisons, and a method is given for adjusting the tabulated values to cover the situation where the variance of the control mean is smaller than thevariance of the treatment means.
Abstract: Some time ago, a multiple comparison procedure for comparing several treatments simultaneously with a control or standard treatment was introduced by the present author (Dunnett [1955]). The procedure was designed to be used either to test the significance of the differences between each of the treatments and the control with a stated value 1 - P for the joint significance level, or to set confidence limits on the true values of the treatment differences from the control with a stated value P for the joint confidence coefficient. Thus the procedure has the property of controlling the experimentwise, rather than the per-comparison, error rate associated with the comparisons, in common with the multiple comparison procedures of Tukey [unpublished] and Scheffe [1953]. In the earlier paper, tables were provided enabling up to nine treatments to be compared with a control with joint confidence coefficient either .95 or .99. Tables for both one-sided and two-sided comparisons were given but, as explained in the paper, the two-sided values were inexact for the case of more than two comparisons as a result of an approximation which had to be made in the computations. The main purpose of the present paper is to give the exact tables for making two-sided comparisons. The necessary computations were done on a General Precision LGP-30 electronic computer, by a method described in section 3 below. The tables are given here as Tables II and III; these replace Tables 2a and 2b, respectively, of the previous paper. In addition to providing the exact values, a method is given for adjusting the tabulated values to cover the situation where the variance of the control mean is smaller than the variance of the treatment means, as occurs for example when a greater number of observations is allocated to the control than to any of the test treatments. Furthermore, the number of treatments which may be simultaneously compared with a control has been extended to twenty. 482

TL;DR: The conditions under which enzymic hydrolysis is carried out are the same as in the King-Armstrong method, as modified by King (1951), the amino-antipyrine reagent (A.A.P.) being used to estimate the phenol liberated.
Abstract: Plasma phosphatase was first determined by Martland (1925) and then by Kay (1930), using glycerophosphate and estimating the inorganic phosphate liberated at 370 C. at a specified pH and in a given time. The procedure has been variously modified and simplified by Jenner and Kay (1932), Bodansky (1933), Shinowara, Jones, and Reinhart (1942). Several substrates, other than glycerophosphate, have also been used, e.g., phenyl phosphate (with determination of either the liberated phenol, King and Armstrong, 1934, or phosphate, King, Abul-Fadl, and Walker, 1951), nitro-phenyl phosphate (by the colour of the liberated nitrophenol, Ohmori, 1937; King and Delory, 1939; Bessey, Lowry, and Brock, 1946), naphthyl phosphate (by determination of naphthol by a diazo method, Seligman, Chauncey, Nachlas, Manheimer, and Ravin, 1951), phenolphthalein phosphate (by the colour of alkaline phenolphthalein, Bray and King, 1943; Huggins and Talalay, 1945). Of the.se procedures, the Bodansky (glycerophosphate) and the King-Armstrong (phenyl phosphate) are perhaps the most widely used. King and Armstrong (1934) determined free phenol, liberated from phenyl phosphate by the phosphatase, by either the Folin and Ciocalteu (1927) phosphomolybdic reagent or by the diazo reaction, and preferred the former. Both procedures required the precipitation and removal of the plasma proteins subsequent to the hydrolysis of the substrate. In 1951 Grifols Lucas proposed a procedure for determination of the free phenol, which did not require removal of the proteins. This was based on the 4-amino-antipyrine reaction of Gottlieb and Marsh (1946). In this method the conditions under which enzymic hydrolysis is carried out are the same as in the King-Armstrong method, as modified by King (1951), the amino-antipyrine reagent (A.A.P.) being used to estimate the phenol liberated. 4-Amino-antipyrine reacts with certain phenolic substances in the presence of alkaline oxidizing agents to produce quinonoid substitution products. These give a red colour proportional to the phenol present, and can be determined colorimetrically. Grifols-Lucas found that A.A.P. does not react with plasma proteins, and their removal is unnecessary when phosphatases are estimated.
