  • Medicinal chemistry is a discipline at the intersection of chemistry, especially synthetic organic chemistry, and pharmacology and various other biological specialties, where they are involved with design, chemical synthesis and development for market of pharmaceutical agents (drugs). Compounds used in medical applications are most often organic compounds, which are often divided into the broad classes of small organic molecules and biologics, the latter of which are most often medicinal preparations of proteins. Inorganic and organometallic compounds are also useful as drugs.

  • Drug Administration be very precise. (Standardized medicinal teaspoons and tablespoons are available.) Eye drops and nose drops (A) are designed for application to the mucosal surfaces of the eye (conjunctival sac) and nasal cavity, respectively. In order to prolong contact time, nasal drops are formulated as solutions of increased viscosity. Solid dosage forms include tablets, coated tablets, and capsules (B). Tablets have a disk-like shape, produced by mechanical compression of active substance, filler (e.g., lactose, calcium sulfate), binder, and auxiliary material (excipients).

  • Introduction: 3,4-Methylenedioxyamphetamines (MDAs), which were described as a new drug class “entactogens” a by Nichols [1], are being abused to enhance mutual understanding, communicativeness and empathy together with their hallucinogenic effects [1–3]. They are known as a group of designer drugs, and include 3,4-methylenedioxyamphetamine(MDA), 3,4-methylenedioxymethamphetamine(MDMA), 3,4-methylenedioxyethylamphetamine (MDEA) and N-methyl-1-(3,4-methylenedioxyphenyl)-2-butanamine(MBDB) ( Fig. 7.1).

  • In a certain sense, the field of drug metabolism (DM) is standing still. More specifically, the basic experiment of drug metabolism (i.e., administering a new drug to an animal or human and determining the structures, amounts, and disposition of the metabolites) has changed very little over a period of decades. Remarkably, the experimental design and resulting data set from a typical absorption, distribution, metabolism, and excretion (ADME) study conducted today would be instantly recognized and understood by DM scientists from 50 years ago.

  • The abuse of amphetamines is of national concern from a public health perspective. Review of this subject is timely and important, because the problem of amphetamine-like drugs has recently been amplified by the introduction of designer drugs in the illicit market. There has been an increasing number of attempts by chemists in clandestine laboratories to synthesize structurally altered congeners that might intensify the moodaltering property of this class of compounds.

  • A key component of the quality of pharmaceutical drugs is the control of impurities. It is important to identify and quantify levels of impurities that may be present to provide safe, effective and well-controlled medicines. The measurement and identification of impurities to today’s standards presents significant challenges to the analytical chemist.

  • Discovery of a new chemical entity that exerts pharmacological effects for curing or treating diseases or relieving symptoms is only the first step in the drug developmental process. In the developmental cycle of a new drug, the delivery of a desired amount of a therapeutic agent to the target at a specific time or duration is as important as its discovery. In order to realize the optimal therapeutic outcomes, a delivery system should be designed to achieve the optimal drug concentration at a predetermined rate and at the desired location....

  • Carbohydrates are sugars and starches derived from cereals, tubers, roots, and other substances such as cellulose and lignin from plant cell walls, vessels and woody tissues. Carbohydrates do mainly provide energy for maintenance and production. A surplus of energy is stored as body fat. A part of the carbohydrates is crude fibre (CF), the remaining is nitrogen-free extract (NFE). The latter consists of sugars, starches and sugar-like substances. Sugars and starches are much easier to digest than CF.
