Medicinal plants are used in the treatment of different ailments. They cannot be distinguished from other plants by morphological characteristics except their pharmacological effects and contain therapeutic agents. Non-medicinal plants are morphologically similar to medicinal plants except some of the members produce active compounds that function either as poisons, pesticides, hallucinogens or teratogens. Poisonous plants produce poison, and pesticide plants are useful in pestmanagement. Poisons and pesticides cause injury, illness, or death to a person if he tastes, smells, and gets it on skin or in eye by their local or systematic action or both. However, the boundary line between medicinal and non-medicinal poisonous, pesticide, hallucinogen plants, etc., is not sharply demarcated, e.g., Azadirachta indica, Malus sp., Prunus spp., Manihot esculenta, Abrus precatorius, Brugmansia sp., Cicuta douglasii, Colchicum autumnale, Datura spp., Digitalis purpurea, Nepenthes attenboroughii, Nerium oleander, Ricinus communis, Strophanthus gratus, Strychnos nux-vomica contain different bioactive compounds including azadirachtin, nimbin, amygdalin, linamarin, and lotaustralin (cyanogenic glycoside), abrin, ricin (ribosome-inactivating protein), aconitine (alkaloid), scopolamine, hyoscyamine, atropine (tropane alkaloids), solanine (glycoalkaloid), nerioside, oleandroside, ouabain (cardiac glycoside); saponins, strychnine (extremely bitter deadly alkaloid), etc. which may be used either as drug principles or poisons or toxins depending on dose and intention of use. Plant-derived pesticides like pyrethrin, rotenone, nicotine, strychnine, and scilliroside from Chrysanthemum cinerariifolium, Pachyrhizus erosus, Nicotina tabacum, S. nux-vomica, Drimia maritime, respectively, are widely used. Hallucinogens are psychoactive agents of natural origin and cause distortions in perceptions of reality (hallucinations) by disrupting the interaction of nerve cells and the neurotransmitter serotonin. Hallucinogens are mostly alkaloids, and mescaline, psilocin, psilocybin, ibogaine, LSD, etc. are some of the examples of common hallucinogen drugs. Topically active hallucinogens include solanaceous belladonna, henbane, mandrake, datura. Pollen from hundreds of weed, grass, and tree plant species, e.g., ragweed, maple, oak, Acacia, Bermuda grass, castor bean, red clover can trigger allergic reactions (allerginosis) in many people every year. Teratogens affect the development of an embryo, pregnancy or may cause a birth defect in the child. Diverse group of compounds, e.g., vitamin D, quinine, anagyrine, and other alkaloids aspirin, marijuana, cannabinols, etc., have shown teratogenicity compounds are synthesized by different plant of the genera including Lupinus, Veratrum, Conium, Astragalus, Nicotiana, Trachymene, Datura, Prunus, Sorghum, Senecio. Some of these plants also cause congenital defects. Natural color and dyes are obtained from plants, animals, or minerals without chemical processing. Roots, berries, bark, leaves, and wood of plants, as well as fungi and lichens, are the major natural sources. Many of the natural dyes like turmeric, annatto, and saffron are food additives and some have pharmacological effects and possible health benefits. The pharmacological effects of medicinal plants are mainly due to their secondary metabolites (e.g., alkaloids, terpenoids, phenolics, glycosides, antibiotics.) produced in the secondary metabolic pathways, which are often species specific, i.e., found in only a small set of species in a narrow phylogenetic group while the primary metabolic pathways and primary metabolites (e.g., carbohydrates, proteins, lipids, nucleic acids, and others) are ubiquitous in plant species. Innumerable numbers of medicinal herbs or their active therapeutic secondary metabolites are used in both traditional and modern systems of medicines. The secondary metabolites may be grouped as nitrogenous (e.g., alkaloids, non-protein amino acids, amines, cyanogenic glycosides, glucosinolates.) and non-nitrogenous (e.g., terpenoids, steroids, saponins, phenolics, flavonoids, polyacetylenes, polyketides, phenylpropanoids.) metabolites. Therapeutically important alkaloids include morphine and codeine from the opium poppy, cocaine from the coca plant, atropine from the deadly nightshade Belladonna, vincristine and vinblastine from the periwinkle, quinine from the bark of the cinchona, caffeine from coffee, tea, and cola plants, nicotine is present in tobacco. Monoterpenes are exemplified by the aromatic oils (e.g., menthol) contained in the leaves of some members of mint family, and pyrethroids are present in the flowers of Chrysanthemum; diterpenes paclitaxel (taxol) is found in bark of the Pacific yew tree; triterpenoids (plant steroids) phytoecdysones are a group of plant sterols are obtained from Tinospora, Asparagus; tetraterpenoids include important pigments (e.g., beta-carotene, lycopene) and are available in colored p…

Inspired by the biogenetic synthesis of benzofuro-indoline-containing natural products, we designed an oxidative coupling between phenol and N-acetyl indoles. This straightforward and direct radical process, mediated by 2,3-dichloro-5,6-dicyano-1,4-benzoquinone and FeCl 3 allowed the regioselective synthesis of benzofuro[3,2-b]indolines, whose structure is found in the natural product phalarine.

Melanins are the ubiquitous pigments distributed in nature. They are one of the main pigments responsible for colors in living cells. Birds are among the most diverse animals regarding melanin-based coloration, especially in the plumage, although they also pigment bare parts of the integument. This review is devoted to the main characteristics of bird melanins, including updated views of the formation and nature of melanin granules, whose interest has been raised in the last years for inferring the color of extinct birds and non-avian theropod dinosaurs using resistant fossil feathers. The molecular structure of the two main types of melanin, eumelanin and pheomelanin, and the environmental and genetic factors that regulate avian melanogenesis are also presented, establishing the main relationship between them. Finally, the special functions of melanin in bird feathers are also discussed, emphasizing the aspects more closely related to these animals, such as honest signaling, and the factors that may drive the evolution of pheomelanin and pheomelanin-based color traits, an issue for which birds have been pioneer study models.

In search for potent and selective beta3-adrenergic receptor (beta3-AR) agonists as potential drugs for the treatment of type II diabetes and obesity, a novel series of 1-(3-chlorophenyl)-2-aminoethanol derivatives were prepared and evaluated for their biological activity at human beta1-, beta2-, and beta3-ARs and rat beta3-AR expressed in Chinese hamster ovary (CHO) cells. Replacement of the right-hand side (RHS, benzene ring) in the ‘first generation’ beta3-AR agonists BRL 37344 and CL 316243 with a 1H-indole ring gave compound 31 with unique pharmacological properties among beta3-AR agonists. Initial in vitro assays showed that 31 possesses modest rat and human beta3-ARs agonistic activity. Introduction of various substituent into the indole nucleus of 31 afforded a number of compounds with good beta3-ARs agonistic activity. In particular, 90 having a carboxylic acid functionality at the 7-position of the indole nucleus showed the most potent human beta3-AR agonistic activity. Finally, optical resolution of 90 led to the identification of the most promising compound, [3-[(2R)-[[(2R)-(3-chlorophenyl)-2-hydroxyethyl]amino]propyl]-1H- indol-7-yloxy]acetic acid (96, AJ-9677). This compound exhibited potent human beta3-AR agonistic activity (EC50 = 0.062 nM, IA = 116%) with 210- and 103-fold selectivity over human beta2-AR and beta1-AR, respectively. Compound 96 also exhibited potent rat beta3-AR agonistic activity (EC50 = 0.016 nM, IA = 110%). Moreover, repeated oral administration of 96 inhibited body weight gain and significantly decreased glucose, insulin, free fatty acid, and triglyceride concentrations in plasma in KK-Ay/Ta mice. On the basis of this pharmacological profile, 96 entered clinical development as a drug for the treatment of type II diabetes and obesity.

Biofilms formed by bacteria on plant roots play an important role in maintaining an optimal rhizosphere environment that supports plant growth and fitness. Bacillus subtilis is a potent plant growth promoter, forming biofilms that play a key role in protecting the host from fungal and bacterial infections. In this work, we demonstrate that the development of B. subtilis biofilms is antagonized by specific indole derivatives that accumulate during symbiotic interactions with plant hosts. Indole derivatives are more potent signals when the plant polysaccharide xylan serves as a carbon source, a mechanism to sustain beneficial biofilms at a biomass that can be supported by the plant. Moreover, B. subtilis biofilms formed by mutants resistant to indole derivatives become deleterious to the plants due to their capacity to consume and recycle plant polysaccharides. These results demonstrate how a dynamic metabolite-based dialogue can promote homeostasis between plant hosts and their beneficial biofilm communities.
