专利号:WO-2023030277-A1 优先权日:2021-08-30 标 题:Method for fully liquid-phase synthesis of grnh nonapeptide amide analog 发明人:SUN PENGCHENG; PAN JING; WU JUNYONG; TANG YONGBO; Du Yixiong; GUO LIN 权利人:HUNAN MICRO PEPTIDE BIOMEDICAL CO LTD 摘要:Provided is a method for fully liquid-phase synthesis of a GRnH nonapeptide amide analog, which belongs to the technical field of medicine synthesis. The method comprises respectively synthesizing a 'Trp-Ser-Tyr' fragment, an 'R-Leu' fragment, a 'Pyr-His' fragment and 'Arg-Pro-Hunan T', wherein, R = D-Ala (alarelin), D-Leu (leuprorelin), D-Trp (deslorelin) and D-His (histrelin), and obtaining the GRnH nonapeptide amide analog with high yield and high purity by means of a '3 +2 +2 +2' fragment condensation method. The synthesis method is environmentally friendly, mild, and free of any highly toxic and poisonable reagents. The cost is greatly reduced and the synthesis method is very suitable for large-scale production.

专利号:US-2006287520-A1 优先权日:2005-05-16 标 题 :Synthesis of salinosporamide A and analogues thereof 发明人:DANISHEFSKY SAMUEL J; ENDO ATSUSHI 权利人:DANISHEFSKY SAMUEL J; ENDO ATSUSHI 摘要:A novel synthesis of salinosporamide A is provided. Salinospoamide A as well as structurally related natural products, omuralide and lactacystin, have been shown to be proteasome inhibitors. Therefore, these compounds as well as analogues of these natural products may be useful in the treatment of proliferative diseases such as cancer, autoimmune diseases, diabetic retinopathy, etc. The invention provides for the synthesis of salinosporamide A as well as analogs thereof using a convenient point for derivatization of the bicyclic core. Pharmaceutical compositions and method of using the inventive compounds are also provided.
专利号:US-12162849-B2 优先权日:2018-12-21 标题 :Synthesis of 3-methyl-1,2,4-thiadiazole-5-carbohydrazide or of the methyl-d3 deuterated form thereof 发明人:HOVEYDA HAMID; DUTHEUIL GUILLAUME 权利人:OGEDA SA 摘要:The present invention relates to a method of synthesis of compound (I), wherein R1 represents methyl or methyl-d3, thus corresponding to 3-methyl-1,2,4-thiadiazole-5-carbohydrazide or to the methyl-d3 deuterated form thereof. These compounds are useful as key intermediates in the synthesis of pharmaceutical compounds, especially fezolinetant and deuterated fezolinetant.
专利号:US-7910623-B2 优先权日:2005-07-22 标 题 :Synthesis of scabronines and analogues thereof 发明人:DANISHEFSKY SAMUEL J; WATERS STEPHEN P 权利人:SLOAN KETTERING INST CANCER 摘要:A novel synthesis of scabronines, which are related to a broader class of angularly fused tricyclic diterpenoids known as cyathanes, is provided. Scabronine G, its methyl ester derivative, and other analogs have been shown to have neurotrophic activity. Therefore, these compounds are particularly useful in treating neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, Huntington's diseases, etc. The invention provides for the synthesis of scabronines as well as analogs thereof. Pharmaceutical compositions and method of using the inventive compounds are also provided.
