专利号:WO-2024013633-A1 优先权日:2022-07-11 标 题 :Process for the synthesis of vitamin k2 发明人:SHASTRI MAYANK; BAIKAR MRUNALI H; VORA PARIN K; BNS RAJU 权利人:SYNERGIA LIFE SCIENCES PVT LTD 摘要:The present disclosure relates to the synthesis of Vitamin K2 bearing varying prenyl side chains. The synthesis comprises the reaction of phenyl sulfone of tert-butyl dimethyl silyl (TBDMS) protected mono prenyl menadiol with prenyl halides bearing varying prenyl units in the presence of the phase transfer catalyst followed by reductive desulphonation to yield TBDMS ether of Vitamin K2. The TBDMS ether is then oxidized in the presence of chromium trioxide and periodic acid to yield the corresponding Vitamin K2.

The present disclosure also provides compositions including one more farnesene derivatives prepared using the disclosed methods.
专利号:US-12194020-B2 优先权日:2017-12-22 标 题:Reversing baldness through cannabinoid receptor activation 发明人:POSTREL RICHARD 权利人:POSTREL RICHARD 摘要:This invention reverses male pattern baldness by shocking dormant hair follicles out of their androgen induced hibernation phase back to the active hair-growing anagenic phase. The invention integrates two functions: 1) It blocks synthesis of compounds holding the follicles in the telogenic/hibernating phase and 2) It stimulates synthesis of compounds animating the hair-growing/anagenic phase in the follicular activity cycle. One preferred embodiment comprises an enzyme inhibitor blocking the conversion of testosterone to dihydrotestosterone (DHT), a flavonoid simultaneously increasing synthesis of prostaglandins alternative to prostaglandin D2, and a selected cannabinoid compound stimulating restore the hair follicle to its normal growth cycle. This novel trimodal therapy restores the hair follicles to their normal cycling processes and maintains these restorative properties so long as this rebalance in maintained.

The synthesis of such halonium compounds, compounds made using such halonium compounds, and synthesis of natural compounds, including decalins, using the halonium compounds is also disclosed. A representative halonium compound of the disclosure is:
专利号:US-7439027-B2 优先权日:1995-01-13 标题 :Method for modulating process mediated by farnesoid activated receptors 发明人:EVANS RONALD M; FORMAN BARRY M; WEINBERGER CARY A 权利人:SALK INST FOR BIOLOGICAL STUDI; LIGAND PHARM INC; USA 摘要:Farnesyl pyrophosphate, the metabolically active form of farnesol, is a key precursor in the synthesis of cholesterol, carotenoids, steroid hormones, bile acids and other molecules involved in cellular growth and metabolism. A nuclear receptor has been identified that is transcriptionally activated by farnesol and related molecules. This novel signaling pathway can be modulated by the use of key metabolic intermediates (or analogs and/or derivatives thereof) as transcriptional regulatory signals.
