摘要:
Certain cis-N-(2-amino-cycloalophatic)benzamides of the formula ##STR1## where m is 0, n is 2, r is alkyl, R.sub.1 and R.sub.2 are taken together with the nitrogen denote a pyrrolidine ring, X and Y are hydrogen or a halogen having an atomic number of from 9 to 35, e.g., cis-3,4-dichloro-N-methyl-n[2-(1-pyrrolidinyl)cyclohexyl]benzamide, and salts thereof, have been found to have CNS seizure blocking or preventing drug action, e.g., anti-convulsant drug properties with little or no analgesic properties.
摘要:
The present invention provides novel .omega.-(3-pyridynl) oxa-, thia-, and aza- alkanoic acids and esters thereof, which are useful as thromboxane A.sub.2 (TXA.sub.2) inhibitors and as such represent potent pharmacological agents.
摘要:
The invention concerns a novel nogamycin having a heretofore unknown configuration and novel analogs which are active against various microorganisms. The invention also includes novel methods of making substituted and unsubstituted nogamycin having an essentially pure isomeric form of a preferred configuration.
摘要:
The present invention provides novel compositions of matter and processes for their preparation. More particularly, the present invention consists of novel chemical intermediates and associated processes for the preparation of khellin and analogues thereof, which have demonstrated antiatherosclerotic activity.
摘要:
A process for converting 1,2-saturated 3-keto steroids to 1,2-dehydro steroids which are useful steroid intermediates. The process involves exposing the substrate to steroid-1-dehydrogenase activity in the presence of an added electron carrier and one or more added scavengers of a toxic oxygen species.
摘要:
Prostacyclin (PGI.sub.2) analogs having a 6a-carba feature, for example a compound of the formula ##STR1## said analogs having pharmacological activity. Processes for preparing them and the appropriate intermediates are disclosed.
摘要:
The present invention provides novel renin-inhibiting peptides of the formula X-A.sub.6 -B.sub.7 -C.sub.8 -D.sub.9 -E.sub.10 -F.sub.11 -G.sub.12 -H.sub.13 -I.sub.14 -Z, having a lactam pseudo-dipeptide at C.sub.8 -D.sub.9 positions, X and Z are terminal groups, and the remaining variables are absent or are amino acid residues. Such inhibitors are useful for the diagnosis and control of renin-dependent hypertension.
摘要:
An apparatus for internally electropolishing tubes in which a plurality of elongate tubes are horizontally supported and rotatably driven about their length axes. An outlet fitting including an end dam permits rotation of the tube outlet end therein, allows escape of gases from the upper portion of the tube, and permits overflow of electrolyte liquid thereover and fixedly supports the end of a cathode rod. The cathode rod is formed as two aligned, axially adjacent partial length sections. The positive terminal of an electric current supply connects at a plurality of points to the tube along its length and connects at its negative terminal individually to the outer ends of the two cathode sections.
摘要:
C.sub.16 -unsaturated corticoids are readily transformed to the corresponding 16.alpha.-methyl-17.alpha.-hydroxy corticoids by use of a .DELTA..sup.17 (.sup.20)-20-silyl ether.
摘要:
The present invention relates to novel methods of preparing a wide variety of spectinomycin analogs and biologically acceptable salts thereof. Further, the invention relates both to novel intermediates and novel products therein. The novel products are spectinomycin analogs which can be used for the same biological purposes as spectinomycin. The processes of the invention provide for novel intermediates that are versatile and highly reactive exocyclic enones.
