Compounds with triple bonds to each side of a double bond. Many of these are CYTOTOXINS and are researched for use as CYTOTOXIC ANTIBIOTICS.
Glycosylated compounds in which there is an amino substituent on the glycoside. Some of them are clinically important ANTIBIOTICS.
Chemical substances, produced by microorganisms, inhibiting or preventing the proliferation of neoplasms.
Changing an open-chain hydrocarbon to a closed ring. (McGraw-Hill Dictionary of Scientific and Technical Terms, 5th ed)
"Chemical Engineering is a branch of engineering that deals with the design, construction, and operation of plants and machinery for large-scale chemical processing of raw materials into finished or partially finished products and for the disposal or recycling of byproducts."

I'm sorry for any confusion, but "San Francisco" is a city in the state of California, United States, and does not have a medical definition. If you have any medical questions or terms you would like defined, I'd be happy to help!
The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.
Publications printed and distributed daily, weekly, or at some other regular and usually short interval, containing news, articles of opinion (as editorials and letters), features, advertising, and announcements of current interest. (Webster's 3d ed)
Large collections of small molecules (molecular weight about 600 or less), of similar or diverse nature which are used for high-throughput screening analysis of the gene function, protein interaction, cellular processing, biochemical pathways, or other chemical interactions.
Process that is gone through in order for a drug to receive approval by a government regulatory agency. This includes any required pre-clinical or clinical testing, review, submission, and evaluation of the applications and test results, and post-marketing surveillance of the drug.
