摘要:
Purified Clausenamide of the formula ##STR1## is obtained by extraction of leaves of Clausena lansium followed by purification, Reduction products, ethers, etc. can be produced. The compounds are effective in treating hypoxia and amnesia.
摘要:
A pharmacologically active .epsilon.-valerolactam has been isolated from the leaves of Clausena lansium. This compound and its derivatives have the formula ##STR1## where R is hydrogen or a C.sub.1 -C.sub.18 -acyl group. It has been found that these compounds are useful in the treatment of hypoxia and as antiamonestics.
摘要:
Compounds of the general formula ##STR1## wherein R.sub.1 represents hydrogen, an acyl group having 1 to 18 carbon atoms or both R.sub.1 together the group ##STR2## R.sub.2 represents hydrogen or a methyl group, have been isolated in small amounts from the leaves of Clausena lansium. The new compounds are to be used for the production of compositions for the use of the treatment of acute and chronical viral hepatitis, liver intoxication, hypoxia or amnesia.
摘要:
A pharmacologically active phenyl-substituted bicyclic lactam has been isolated from the leaves of Clausena lansium. This compound and its derivatives have the formula ##STR1## Where R is hydrogen of a C.sub.1 -C.sub.18 -acyl group. It has been found that these compounds are useful in the treatment of hypoxia and as antiamnestics.
摘要:
A process for the preparation of compound of the formula ##STR1## in which R.sup.1 --represents ##STR2## and R.sup.2 --represents hydrogen, fluorine, chlorine or bromine. Comprising cyclizing compounds of the formula ##STR3## and, in a further step, either a) reducing stereo-specifically to give compounds of the formula in which R.sup.1 represents ##STR4## or b), to give compounds of the formula in which R.sup.1 represents ##STR5## or by c) forming compounds of the formula ##STR6## followed by stereoselective reduction to give compounds in which R.sup.1 represents ##STR7##
摘要:
N-substituted amide derivative represented by the formula ##STR1## wherein A is --CH(OH)-- or --C(.dbd.O)--, R.sup.1 is a hydrogen atom or anlkyl group having 1 to 3 carbon atoms, and R.sup.2 is an alkyl group having 1 to 6 carbon atoms, are disclosed. These compounds are useful for prevention and therapy for liver diseases.
摘要:
Processes for the preparation of compounds of the formula ##STR1## in which R and R.sup.1 are identical or different and represent hydrogen or halogen, in the racemic form or in the form of its pure enantiomers by cyclicizing compounds of the formula ##STR2## with 2,6-lutidine or by cyclicizing compounds of the formula ##STR3## with diethyl azodicarboxylate. Compounds where R is halogen are new and are useful as cerebral therapeutics, nootropics or in the reduction of increased glutamine pyruvate transaminase in serum.

摘要:
An energy adjusting method for controlling output energy of a fuel cell group, wherein at least one of the fuel cell group and a secondary battery group drives a load is disclosed. The voltage of the fuel cell group is boosted by a boost regulation module to generate a first adjustment voltage. The boost regulation module boosts the voltage of the fuel cell group according to a first control signal. The first adjustment voltage is dropped by a drop regulation module to generate a second adjustment voltage to the load. The drop regulation module drops the first adjustment voltage according to a second control signal. At least one of the fuel cell group, the boost regulation module, the drop regulation module and the load is detected to generate a detection result. The first and the second control signals are generated according to the detection result.
摘要:
A method for adjusting a displayed frame, an electronic device, and a computer readable medium thereof are provided. In the present method, a connection line between both eyes of a user is obtained. Then, a relation between the connection line and a screen of the electronic device is calculated. Finally, a frame currently displayed on the screen is rotated according to the relation, and the rotated frame is displayed on the screen. Thereby, the frame is automatically adjusted to an angle most suitable for the user without any action performed by the user on the electronic device.
