This study was carried out to evaluate the anti-nociceptive and anti-inflammatory activities of carbon tetrachloride extract (CTCE) of Azadirachta indica fruit skin and its isolated constituent azadiradione at two different dose levels (50 and 100 mg kg⁻¹ body weight). Anti-nociceptive screening by
Azadirachta indica is well known medicinal plant mentioned in ancient herbal texts. It has been extensively used in Ayurvedic, Unani and Homoeopathic medicine and has become a luminary of modern medicine. As part of our drug discovery program we isolated azadiradione from the ethanolic extract of
Human pancreatic α-amylase (HPA) inhibitors offer an effective strategy to lower postprandial hyperglycemia via control of starch breakdown. Limonoids from Azadirachta indica known for their therapeutic potential were screened for pancreatic α-amylase inhibition, a known anti-diabetic target.
Huntington's disease (HD) is an autosomal dominantly inherited neurodegenerative disorder caused by expansion of CAG repeats in the coding area of huntingtin gene. In the HD brain, mutant huntingtin protein goes through proteolysis, and its amino-terminal portion consisting of polyglutamine repeats
Aggregation of proteins with the expansion of polyglutamine tracts in the brain underlies progressive genetic neurodegenerative diseases (NDs) like Huntington's disease and spinocerebellar ataxias (SCA). An insensitive cellular proteotoxic stress response to non-native protein oligomers is common in
Terpenoids were isolated using chromatographic purification through solvent purification technique and identified as Azadirone (1), Epoxyazadiradione (2) Azadiradione (3) Gedunin (4) Nimbin (5) Salannin (6) Azadirachtin A (7) and Azadirachtin B (8) from Azadirachta indica. Out of eight compounds,
One new compound, 2H, 3H-cyclopent[b] furo [2',3':4,5] naphtho [2,4-d] heptlactone-[3,7] furan-6aceticacid, 3-(acetyloxy)-8-(3-furyl)-2a, 4a, 4b, 4c,5,5a, 6, 6a, 8, 9,9a, 10a,10b-13 hydrogen-2a,5a,6a,5-tetramethyl-3-[[(2E)-2-methyl-1-oxo-2-butenyl]oxy]-methyl ester, named azadirachta R (1), along
Mahmoodin [1], a new limonoid, has been isolated from Azadirachta indica (neem) oil, along with seven known tetranortriterpenoids, azadirone, epoxyazadiradione, nimbin, gedunin, azadiradione, deacetylnimbin, and 17-hydroxyazadiradione. A new protolimonoid, naheedin [3], has been obtained from the
The azadirachtin, salannin, nimbin, deacetylnimbin, azadiradione and epoxyazadiradione contents were determined by HPLC in the fractions prepared from the kernel of neem fruits (Azadirachta indica) collected at different ripening stages. The fully mature fruit (yellow fruits) kernels contained the
Thirty-five limonoids, including 15 of the azadiradione type (1-15), five of the gedunin type (16-20), four of the azadirachtin type (21-24), nine of the nimbin type (25-33), and two degraded limonoids (34, 35), isolated from Azadirachta indica seed extracts, were evaluated for their cytotoxic
Natural tetranortriterpenoids such as cedrelone from Toona ciliata, azadiradione from Azadirachta indica, limonin, limonol and nomilinic acid from Citrus medica, along with some cedrelone derivatives were tested for their antifungal activity against Puccinia arachidis, a groundnut rust pathogen.
The head and neck squamous cell carcinoma (HNSCC) constitute about 90% of all head and neck cancers. HNSCC falls in the top 10 cancers in men globally. Epoxyazadiradione (EPA) and Azadiradione (AZA) are the limonoids derived from the medicinal plant Azadirachta indica (popularly known as Neem).
