Title: Process for producing factor for promoting letting out growth hormone of human pancreatic origine
Inventor: RIVIER JEAN E
IPC: A23K1/16
Filed: 1983-10-03
Abstract: Two surprisingly active fragments of human pancreatic GRF have been synthesized, along with an analog which exhibits good biological activity. The synthetic peptides are extremely potent in stimulating the release of pituitary GH in humans and nonhuman animals and have the general formula:
 H-Tyr-Ala-Asp-Ala-Ile-Phe-Thr-Asn-Ser-Tyr-Arg-Lys-Val-Leu-R15-Gln-Leu-Ser-Ala-Ar g-Lys-Leu-Leu-Gln-Asp-lle-Met-Ser-Arg-Gln-Gly-Glu-Ser-Asn-Gln-Glu-Arg-Gly-R40-Y wherein R15 is Gly or D-Ala, R40 is Ala or des-R40 and Y signifies the carboxyl moiety of the amino acid residue at the C-terminal and is the radical -COOR1, -CR1O, -CONHNHR1, -CON(R1)(R2) or -CH2OR1, with R1 and R2 being lower alkyl or hydrogen. The two fragments include the 29 or 32 N-terminal residues and are each amidated at the C-terminus. These peptides, as well as nontoxic salts thereof, may be administered therapeutically to animals, including humans.

Abstract: Substituted phenylsulphonamides having the formula: <CHEM>  where the variables are as defined in Claim 1;   are selective beta-3 adrenergic receptor agonists with very little beta-1 and beta-2 adrenergic receptor activity and as such the compounds are capable of increasing lipolysis and energy expenditure in cells. The compounds thus have very potent activity in the treatment of Type II diabetes and obesity. The compounds can also be used to reduce triglyceride levels and cholesterol levels or raise high density lipoprotein levels or to reduce gut motility. In addition, the compounds can be used to reduce neurogenic inflammation or as antidepressant agents. The compounds are prepared by coupling an aminoalkylphenylsulphonamide with an appropriately substituted alkyl epoxide. Compositions and methods for the use of the compounds in the treatment of diabetes and obesity and for reduction of triglyceride levels and cholesterol levels or raising high density lipoprotein levels or for increasing gut motility are also disclosed.

Abstract: The control arrangement for setting different operating modes in road tankers 1 for liquids, suspensions, etc. serves for connecting an air pump, via a multi-way valve 13, optionally to the suction or pressure side of a line 3 opening out in the tank and, by way of the respectively other side, to a line which opens out in the open. Provided along the line 3a, 3, which opens out in the tank, is a safety valve 10 which, as it responds, connects the line 3 to the ambient air. In addition to the safety valve responding independently to the tank being overfilled or to a positive pressure in the line, provision is made for a self-activating positive-pressure sensor 34 of the safety valve 10 to be connected, via a separate line 11 and a reversing valve 22 controlled by a remote actuator 21, optionally either to the line 3 opening into the tank or to an exterior compressed-air source, preferably the braking line 23 of the vehicle, and thus, if necessary, for the safety valve 10 to be actuated voluntarily via the remote actuator 21. <IMAGE>
