Indian Science Congress
Indian Science Congress Association(ISCA) is a premier scientific organisation of India with headquarters at Kolkata, West Bengal. The association started in the year 1914 in Kolkata and it meets annually in the first week of January. It has a membership of more than 30,000 scientists. The first Indian Science Congress was held in 1914 at the Asiatic Society in Calcutta. After pseudoscientific speeches at the 2019 Indian Science Congress, the congress has established a policy that requires speakers at future conferences to be vetted and scrutinizes the content of their talks. Several prominent Indian and foreign scientists, including Nobel laureates, attend and speak in the congress. Genesis The Indian Science Congress Association (ISCA) owes its origin to the foresight and initiative of two British chemists, namely, Professor J. L. Simonsen and Professor P. S. MacMahon.

Aporphine
Aporphine is an alkaloid with the chemical formula . The IUPAC (International Union of Pure and Applied Chemistry) name of aporphine is ''6-methyl-5,6,6a,7-tetrahydro-4H-dibenzo e,guinoline.'' It is the core chemical substructure of the aporphine alkaloids, a subclass of quinoline alkaloids. It can exist in either of two enantiomeric forms, (''R'')-aporphine and (''S'')-aporphine. Derivatives Many different derivatives have been isolated from plants. For example, many water-lilies (''Nymphaea'' species) produce aporphine alkaloids such as nymphaeine, nymphaline, nupharine, α- and β- nupharidine. ''In vitro'' tests of some aporphine derivatives isolated from ''Cassytha filiformis'', namely actinodaphnine, cassythine, and dicentrine, showed antiparasitic activity against ''Trypanosoma brucei''. Investigation of possible mechanisms revealed that the compounds bind to DNA and act as intercalating agents, besides inhibiting topoisomerase activity. Aporphine natural products o ...

Azasteroids
An azasteroid is a type of steroid derivative which has one of the carbon atoms in the steroid ring system replaced by a nitrogen atom. Two azasteroids, finasteride and dutasteride, are used clinically as 5α-reductase inhibitor 5α-Reductases, also known as 3-oxo-5α-steroid 4-dehydrogenases, are enzymes involved in steroid metabolism. They participate in three metabolic pathways: bile acid biosynthesis, androgen and estrogen metabolism. There are three isozymes of ...s. Some of the 6-azasteroids may prove to be useful drugs, but have yet to reach the pharmaceutical market. References Steroids {{pharmacology-stub ...

Solanum
''Solanum'' is a large and diverse genus of flowering plants, which include three food crops of high economic importance: the potato, the tomato and the eggplant (aubergine, brinjal). It is the largest genus in the nightshade family Solanaceae, comprising around 1,500 species. It also contains the so-called horse nettles (unrelated to the genus of true nettles, ''Urtica''), as well as numerous plants cultivated for their ornamental flowers and fruit. ''Solanum'' species show a wide range of growth habits, such as annuals and perennials, vines, subshrubs, shrubs, and small trees. Many formerly independent genera like '' Lycopersicon'' (the tomatoes) and ''Cyphomandra'' are now included in ''Solanum'' as subgenera or sections. Thus, the genus today contains roughly 1,500–2,000 species. Name The generic name was first used by Pliny the Elder (AD 23–79) for a plant also known as , most likely ''S. nigrum''. Its derivation is uncertain, possibly stemming from the Latin word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrrolines
Pyrrolines, also known under the name dihydropyrroles, are three different heterocyclic organic chemical compounds that differ in the position of the double bond. Pyrrolines are formally derived from the aromate pyrrole by hydrogenation. 1-Pyrroline is a cyclic imine, whereas 2-pyrroline and 3-pyrroline are cyclic amines. Substituted pyrrolines Notable examples of pyrrolines containing various substituents include: * 2-Acetyl-1-pyrroline, an aroma compound with a white bread-like smell * Thienamycin, a beta-lactam antibiotic * MTSL, a chemical used for certain NMR experiments * Pyrrolysine, an unusual proteinogenic amino acid * 1-Pyrroline-5-carboxylic acid, a biosynthetic metabolite * Porphyrin, consisting of two alternating pairs of pyrrol and pyrroline connected via methine (=CH-) bridges ''N''-substituted pyrrolines can be generated by ring-closing metathesis.Marcelle L.

British India
The provinces of India, earlier presidencies of British India and still earlier, presidency towns, were the administrative divisions of British governance on the Indian subcontinent. Collectively, they have been called British India. In one form or another, they existed between 1612 and 1947, conventionally divided into three historical periods: *Between 1612 and 1757 the East India Company set up Factory (trading post), factories (trading posts) in several locations, mostly in coastal India, with the consent of the Mughal emperors, Maratha Empire or local rulers. Its rivals were the merchant trading companies of Portugal, Denmark, the Netherlands, and France. By the mid-18th century, three ''presidency towns'': Madras, Bombay and Calcutta, had grown in size. *During the period of Company rule in India (1757–1858), the company gradually acquired sovereignty over large parts of India, now called "presidencies".
