The metabolism of pineal indoles is closely related to alterations in the light and dark phases of a daily cycle. Recent research showed important interspecies differences in the pineal biochemistry, and a strong impact of monochromatic light on many physiological processes in birds. Therefore, the aims of study were to characterize the metabolism of melatonin-synthesis indoles in the pineal organ of the domestic turkey, and to determine the changes occurring in this metabolism under the influence of different wavelengths and intensities of light. For this purpose, 3-week-old turkeys were kept under 16 lx white light, or under blue, green, and red light with intensities of 16, 32, and 64 lx during the photophase, and after 7 d were sacrificed at 4 h intervals. The activities of melatonin-synthesizing enzymes and the contents of indoles were measured in the same pineal organ. The results revealed that the activities of tryptophan hydroxylase and arylalkylamine N-acetyltransferase, and the levels of all tryptophan derivatives had significant daily changes in birds kept under each light condition used. The profile of pineal indole metabolism in 4-week-old turkeys was characterized by high-amplitude rhythms in the activity of arylalkylamine N-acetyltransferase and the contents of N-acetylserotonin and melatonin, equal relative amounts of serotonin and 5-hydroxyindoleacetic acid, and higher content of melatonin than N-acetylserotonin. The monochromatic light significantly modified the pineal indole metabolism, and its effects were dependent on the color and intensity of light. Pronounced changes occurred in the level of serotonin synthesis and the daily rhythm course of melatonin synthesis.

Leptadenia reticulata (Retz.) Wight and Arn is an important medicinal plant of Asclepiadaceae family. In the present study regeneration was attempted using leaf and nodal explants in Murashige and Skoog’s (MS) medium fortified with sucrose (3%) and different cytokinins like 6-benzyladenine (BA), kinetin (Kn) and adenine sulphate (AdSO(4)) in 5-20 mu M concentration range and auxins like indole-3-acetic acid (IAA), 1-naphthaleneacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D) in 0.1-1.0 mu M concentration range. Through leaf explants total 21.70 +/- 2.06 somatic embryos were recorded in 100% cultures in BA (15 mu M) with AdSO(4) (15 mu M). Further these embryos were transferred to static medium augmented with gibberellic acid (GA(3), 1 mu M) facilitated development of plantlets within 8 weeks. Inoculating nodal explants in BA (10 mu M) with AdSO(4) (10 mu M) formed total 5.10 +/- 0.33 shoots (100% response). Callus and shoot cultures derived through leaf and nodal explants respectively were further qualitatively and quantitatively analyzed for their biosynthetic potential. High-performance thin layer chromatography (HPTLC) fingerprints of the samples confirmed that the in vitro shoots showed almost similar banding patterns in comparison with in vivo shoots in terms of number of peaks and band on TLC plate, whereas in callus samples the banding pattern was differed. Further quantification of p-coumaric acid revealed that in in vivo and in vitro shoots it was in LOD (10 mu g) range but out of LOQ (100 mu g). Whereas it was quantified 78.08 +/- 2.20 mg g(-1) of dry weight (DW) in 6 weeks old callus cultures obtained from BA (20 mu M) + NAA (0.5 mu M) fortified medium, which indicate that it can become a chemical marker for L. reticulata. This protocol can be utilized for true-to-type plant regeneration as well as conservation of this threatened medicinal plant. Chemical fingerprint can be utilized for authentication of L. reticulata and callus cultures as an alternative source to wild plants for production of p-coumaric acid. Key message SEs were efficiently developed in L. reticulata. In vitro cultures were able to synthesize metabolites but callus is prominent source for p-coumaric acid. Hence it can be alternative to wild plants.

Metal-Free Blue-Light-Mediated Cyclopropanation of Indoles by Aryl(diazo)acetates

Blue-light-mediated cyclopropanation of indoles with aryl(diazo)acetates has been developed. The salient features of this strategy are that it is metal-free, operationally simple and atom-efficient, and that it uses an environmentally friendly energy source. In this protocol, blue light was employed as the sole energy source for the transformation. A variety of cyclopropane-fused indoline compounds was obtained in moderate to excellent yields and high diastereoselectivities under mild conditions.

Synthesis, characterization and electrochemical properties of some biologically important indole-based-sulfonamide derivatives

A new series of indole-based-sulfonamide derivatives (A1-A8) was synthesized by treating 5-fluoro-1H-indole-3-carbohydrazide with different aryl-sulfonyl chloride in the presence of pyridine. All synthesized derivatives (A1-A8) were characterized by different analytical methods. The electrochemical behavior of these compounds (A1-A8) was investigated in detail using cyclic voltammetry (CV) and square wave voltammetry (SWV) at the pencil graphite electrode (PGE). In the present study, the redox behavior of all derivatives varies due to the nature of substitutions in the indole sulfonamide moiety. Various fundamental electrochemical parameters, including the standard heterogeneous rate constants (k(s)), and the electroactive surface coverage (Gamma) were calculated from the obtained CVs. The obtained results shed light on the understanding of structure-activity relationships of this class of compounds.
