Abstract:
The title compds. (I; R1=H, lower alkanoyl; R2=C1-20 straight or side chain alkyl; X=nitrogen or C-methyl), useful as analgesics, were prepd. by reaction of liquid ammonia and isopropenyl derivs. (IV) obtained from dehydration of diacetyl deriv. with thionyl chloride. Diacetyl deriv. was prepared by reaction of anhydrous acetic acid and alcohol(III) obtained from benzopyranone(II) and methyl magnesium bromide in tetrahydrofuran.
Abstract:
The present invention features nucleic acids for recombinant protein expression in mammalian cell culture. The episomal vectors of the invention promote high protein production in mammalian cells expressing the SV40 T Ag or Epstein-Barr virus nuclear antigen (e.g., COS7 or HEK293-6E cells). The methods and systems are useful, for example, in pharmaceutical drug development and cloning, especially for the production of antibodies.
Abstract:
Title compds. useful as analogesics and antidepressants, were prepd. by dehydration of the corresponding 1,2,3,4-tetrahydro derivs. 5H-[1 benzopyrano [3,4-d pyridine (I; R1 = lower alkyl, R2 = alkyl, cycloalkyl, R3 = hydroxy, acyloxy, lower alkoxy, lower alkenyloxy, lower alkoxy, lower alkenyloxy, lower alkynyloxy) was prepd. by refluxing the 1,2,3,4-tetrahydro-5H [1 benzopyrano [3,4-d pyridine with pd/c in xylene for 25hr.
Abstract:
PROBLEM TO BE SOLVED: To provide a system for automation of an analyzer for laboratory which uses a container and a liquid container used in the system, and a radio recognition (RFID) tag and a radio recognition (RFID) reader to identify contents thereof.SOLUTION: Radio recognition tags 18 adaptive to guidelines of ISO14443 or ISO15693 or ISO18000 are arranged on an object such as a reagent container, a sample container 14, a microplate, etc. Those tags can be read and written through a movable antenna of an RFID reader or a fixed antenna of the RFID reader. The reading from the RFID tags and the writing to the RFID tags are controlled by software.
Abstract:
PROBLEM TO BE SOLVED: To provide novel solid dispersion pharmaceutical formulations which demonstrate an inhibition of crystallization.SOLUTION: A solid pharmaceutical composition contains: a molecular dispersion of ritonavir (ABT-538); a hydrophilic, amorphous polymer selected from the group consisting of polyvinylpyrrolidone (PVP) and hydroxypropylmethylcellulose (HPMC); and matrix comprising a water soluble carrier which is selected from the group consisting of polyethylene glycol (PEG), pentaerythritol, pentaerythritol tetraacetate, polyoxyethylene stearate, and poly-ε-caprolacton. The matrix includes an amorphous region where the ritonavir resides.
Abstract:
PROBLEM TO BE SOLVED: To provide a pharmaceutical composition improved in dissolution profiles of drugs therein.SOLUTION: The pharmaceutical compositions comprising an ionizable drug or a salt thereof, a crystallization inhibitor and a pH modifier, and measurably improved in dissolution rate of the ionizable drug are provided.
