George R. Pettit
George Robert Pettit II (June 8, 1929 – September 21, 2021) was a Regents’ Professor in Chemistry in the School of Molecular Sciences (SMS) at Arizona State University. He was an internationally renowned and respected researcher in the field of natural anticancer compounds throughout his career of over six decades. Pettit has been honored by the International Cancer Advocacy Network, the American Society of Pharmacognosy, and Washington State University, his alma mater. A special edition of the Journal of Natural Products is dedicated to Pettit, and the French journal ''Médicine Sciences'' paid tribute to him. Pettit’s achievements earned him the designation of Outstanding Investigator by the United States National Institutes of Health National Cancer Institute (NCI). Pettit and his impact on the field of anti-cancer compounds are the subject of the book, “Waging War on Cancer.” Early life and education George Robert “Bob” Pettit was born on June 8, 1929, the ...

Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital let ...

Steroid
A steroid is a biologically active organic compound with four rings arranged in a specific molecular configuration. Steroids have two principal biological functions: as important components of cell membranes that alter membrane fluidity; and as signaling molecules. Hundreds of steroids are found in plants, animals and fungi. All steroids are manufactured in cells from the sterols lanosterol (opisthokonts) or cycloartenol (plants). Lanosterol and cycloartenol are derived from the cyclization of the triterpene squalene. The steroid core structure is typically composed of seventeen carbon atoms, bonded in four " fused" rings: three six-member cyclohexane rings (rings A, B and C in the first illustration) and one five-member cyclopentane ring (the D ring). Steroids vary by the functional groups attached to this four-ring core and by the oxidation state of the rings. Sterols are forms of steroids with a hydroxy group at position three and a skeleton derived from cholestane. ''A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Combretastatin
Combretastatin is a dihydrostilbenoid found in '' Combretum caffrum''. As a class Combretastatins are a class of natural phenols. A variety of different natural combretastatin molecules are present in the bark of '' Combretum caffrum'', commonly known as South African Bush Willow. Despite having a similar name, combretastatins are unrelated to statins, a family of cholesterol lowering drugs. Natural combretastatins Molecules that fall into the combretastatin family generally share 3 common structural features: a trimethoxy "A"-ring, a "B"-ring containing substituents often at C3' and C4', and ftenan ethene bridge between the two rings which provides necessary structural rigidity. Molecules with such an ethene bridge are also stilbenoids, molecules with a non-ethene bridge are dihydrostilbenoids. Molecules with C3' amino and hydroxyl substituents are very active, and molecules with C4' hydroxyl or methoxy substituents are also cytotoxic. Of the natural products presently kn ...

Bryostatin
Bryostatins are a group of macrolide lactones from the marine organism ''Bugula neritina'' that were first collected and provided to JL Hartwell’s anticancer drug discovery group at the National Cancer Institute (NCI) by Jack Rudloe. Bryostatins are potent modulators of protein kinase C. They have been studied in clinical trials as anti-cancer agents, as anti-AIDS/HIV agents and in people with Alzheimer's disease. Biological effects Bryostatin 1 is a potent modulator of protein kinase C (PKC). It showed activity in laboratory tests in cells and model animals, so it was brought into clinical trials. As of 2014 over thirty clinical trials had been conducted, using bryostatin alone and in combination with other agents, in both solid tumors and blood tumors; it did not show a good enough risk:benefit ratio to be advanced further. It showed enough promise in animal models of Alzheimer's disease that a Phase II trial was started by 2010; the trial was sponsored by the Blanchett ...

Cancer Research Institute
The Cancer Research Institute (CRI) is a US non-profit organization funding cancer research and based in New York City. They were founded in 1953 to develop immunologically-based treatments for cancer, and despite their name are a funding body for research rather than a research institute themselves, working with other institutes and organizations. It was founded by Helen Coley Nauts and Oliver R. Grace with a $2,000 grant from Nelson Rockefeller. CRI was created in honor of Nauts' father, William Coley (1862–1936), an American orthopedic surgeon and a pioneer of cancer immunotherapy. Like Dr. Coley, the Institute focuses on immunological treatments for cancer, rather than traditional treatments, such as chemotherapy and surgery. The organization offers research grants to students, postdoctoral fellows, and investigators at medical research institutions throughout the world. It also funds clinical trials testing promising immunotherapies in a variety of cancer types and conv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central Nervous System
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts. It is a structure composed of nervous tissue positioned along the rostral (nose end) to caudal (tail end) axis of the body and may have an enlarged section at the rostral end which is a brain. Only arthropods, cephalopods and vertebrates have a true brain (precursor structures exist in onychophorans, gastropods and lancelets). The rest of this article exclusively discusses the vertebrate central nervous system, which is radically distinct from all other animals. Overview In vertebrates, the brain and spinal cord are both enclosed in the meninges. The meninges provide a barrier to chemicals dissolv ...

Norwich, New York
Norwich is a city and county seat of Chenango County, New York, United States. Surrounded on all sides by the Town of Norwich,. The name is taken from Norwich, England. Its population was 7,190 at the 2010 census. Lt. Warren Eaton Airport (OIC), serving the area, is located north of the city in the town of North Norwich. History The first log cabin was built in 1788 by Col. William Monroe, who served as a drummer boy during the Revolutionary War. The town of Norwich was formed in 1793 from the towns of Union (now in Broome County) and Bainbridge. Afterwards, Norwich, as a "mother town" of the county, lost substantial territory in the formation of new towns. In 1806, Norwich gave up territory to form the towns of Pharsalia, Plymouth and Preston. More of Norwich was lost in 1807 to form parts of the towns of New Berlin and Columbus. In 1808 and 1820, Norwich exchanged territory with the town of Preston. The central community of Norwich set itself off from the to ...
