Abstract: The solid-phase syntheses of [Ala.sup.2 ]-, [D-Leu.sup.2 ]-, [D-Lys.sup.2 ], [Leu.sup.5 ]- and [D-Ala.sup.2, D-Leu.sup.5 ] .beta.-endorphins are described. The synthetic peptides were purified by chromatography on carboxymethylcellulose and partition chromatography on Sephadex G-50. They were characterized by partition chromatography on agarose, thin-layer chromatography, paper electrophoresis, and amino acid analyses of acid and enzymic hydrolysates. Bioassay of the synthetic analogs for analgesic activity by the tail-flick-method showed the D-Leu.sup.2 analog to be 48% as potent as .beta..sub.h -endorphin while the Ala.sup.2, D-Lys.sup.2, Leu.sup.5, and [D-Ala.sup.2, D-Leu.sup.5 ] analogs were 8 to 17% as active.

Abstract: Propionic acid esters of the general formula ##STR1## wherein R.sub.1 is hydrogen, alkyl of from 1 to 6 carbon atoms or phenyl, R.sub.2 is alkyl of from 1 to 6 carbon atoms, alkenyl of from 2 to 6 carbon atoms, alkynyl of from 2 to 6 carbon atoms or phenyl, or R.sub.1 and R.sub.2 together with the carbon atom to which they are attached form a cycloalkane ring containing 4 to 10 carbon atoms which can be mono-, di- or trisubstituted with alkyl of from 1 to 3 carbon atoms, R.sub.3 represents a halogen, trifluoromethyl or nitro, and R.sub.4 and R.sub.5 each represent a hydrogen or halogen atom, processes for their manufacture, herbicidal compositions containing these compounds as the active ingredient and methods of use of the herbicidal compositions are disclosed.

Abstract: Novel hapten compositions consisting of 4-[4-[2-(aminopropyl)]phenyl]butanoic acid and its N-methyl derivative are useful in preparing immunogens which can be respectively employed in the elicitation of antibodies selective to amphetamine and methamphetamine. These antibodies can be used as reagents in immunoassays for these two compounds.

Abstract: The present disclosure is directed to a process for the preparation of cholesterol derivatives from corresponding 21-hydroxymethyl steroidal compounds.

Abstract: A tubular sample or reagent container for analytical devices, such as automated centrifugal analyzers, in which typically a multiplicity of such containers are arranged in a carrier plate or other means which forms part of the analyzers, with each container having a peripheral edge for bearing on the carrier plate. An abutment is provided on the containers disposed below the peripheral edge and at the periphery of the containers, which abutment is deformable in the centripetal direction.

Abstract: The present disclosure is directed to a process and intermediates for the synthesis of Vitamin D.sub.3 metabolites such as 1,25-dihydroxycholecalciferol, 25-hydroxycholecalciferol and 24R,25-dihydroxycholecalciferol from 17-keto steroids via intermediates having the natural steroid configuration at the 20-position. These novel intermediates are prepared from 17-keto steroids by reaction with ethyltriphenylphosphonium halides followed by reaction with formaldehyde to form comounds having the natural steroid configuration at the 20-position and which are suitable substrates for the preparation of the aforementioned Vitamin D.sub.3 metabolites.

Abstract: A multi-step synthesis of chenodeoxycholic acid from 3-keto-bisnorcholenol, a compound readily obtained from the abundant plant sterol .beta.-sitosterol, is described. A key step in the synthesis is the stereoselective microbial introduction of the 7-alpha hydroxy group into 3-keto-bisnorcholenol.

Abstract: A method for the removal of CO from flue gas which comprises contacting a spent noble metal reforming catalyst with flue gas from a cat cracker regenerator at 1000.degree.-1350.degree. F. to effectively oxidize CO to CO.sub.2. The spent catalyst while no longer efficient in a reforming process is found to be effective in reducing the CO level to a concentration range of 5000 parts per million and less.
