Recombinase polymerase amplification (RPA) is a single tube, isothermal alternative to the polymerase chain reaction (PCR). [1] By adding a reverse transcriptase enzyme to an RPA reaction, it can detect RNA as well as DNA, without the need for a separate step to produce cDNA.
This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes).This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).
Phencyclidine or phenylcyclohexyl piperidine (PCP), also known in its use as a street drug as angel dust among other names, is a dissociative anesthetic mainly used recreationally for its significant mind-altering effects. [1] [4] PCP may cause hallucinations, distorted perceptions of sounds, and violent behavior.
PCP itself is composed of three six-membered rings, which can each be substituted by a variety of groups. These are traditionally numbered in the older research as first the cyclohexyl ring, then the phenyl , and finally the piperidine ring, with the different rings represented by prime notation (') next to the number.
Methylenedioxyphencyclidine (3',4'-MD-PCP, MDPCP) is a recreational designer drug with dissociative effects. It is an arylcyclohexylamine derivative, with similar effects to related drugs such as 3-MeO-PCP and 4-MeO-PCP .
PCP's initial design was done at SGI in Melbourne, Australia, by Ken McDonell and Mark Goodwin, starting in October 1993. The pair were joined by Seppo Keronen and Jonathan Knispel, early in 1994. These four produced the initial version of Performance Co-Pilot 1.0, which was released in April 1995 as add-on software for SGI's IRIX operating system.
Rolicyclidine (PCPy) is a dissociative anesthetic that is similar in effects to phencyclidine, but is slightly less potent and has fewer stimulant effects. [2] It instead produces a sedative effect described as being somewhat similar to a barbiturate, but with additional PCP-like dissociative, anaesthetic and hallucinogenic effects. [3]
Procyclidine synthesis: [3] U.S. patent 2,826,590 Procyclidine, 1-cyclohexyl-1-phenyl-3-pyrrolidinopropan-1-ol, is synthesized in exactly the same manner as was seen for trihexyphenidyl, except this time the linear synthesis begins with the preparation of 3-(1-pyrrolidino)propiophenone.
