Ketal Steroids TRIZ Cases
- 19-Substituted Neuroactive Steroids for Consistent GABA Modulation
19-substituted neuroactive steroids improve consistency in GABA-mediated control of brain excitability for CNS disorders, sedation, and anesthesia.
- Plant-Derived BA Route to Ursodeoxycholic Acid Without Animal Raw Materials
This route replaces animal-derived feedstocks with plant-derived BA to address infection risk while enabling industrial ursodeoxycholic acid synthesis.
- GPX4 Inhibitor Compounds for Selective Senescent Cell Elimination
Limited solubility and oral bioavailability constrain existing senolytics; Formula (I) and (II) compounds inhibit GPX4 to target senescent cells.
- Ergosterol-Derived Intermediate Route to Dydrogesterone
Photochemical conversion of readily available ergosterol creates a 10α intermediate for a shorter, higher-yield dydrogesterone route.
- Cyclin-Dependent Kinase Degraders via E3 Ligase Recruitment
Conventional CDK inhibitors can leave systemic concentrations insufficient; bifunctional compounds recruit CDK8/CDK19 to E3 ligases for proteasomal degradation.
- Cholic Acid Derivative Synthesis via Cyclic Enol Ether Intermediates
Segmented synthesis using cyclic enol ether intermediates reduces process complexity and time for producing medically significant bile acid derivatives.
- Desogestrel Synthesis via Selective Oxidation and Hydrogenation
Replacing hazardous reagents with manganese dioxide oxidation and catalytic hydrogenation streamlines the Desogestrel synthetic route.
- 13, 17-Substituted Steroids for GABA Receptor Modulation
Modifying steroid structures at positions 13 and 17 reduces bacterial contamination risk while maintaining anesthetic efficacy.
- Etonogestrel Synthesis via Selective 11-Ketone Oxidation
Selective oxidation of protected steroid intermediates reduces manufacturing costs for hormonal contraceptives.
- 21-Hydroxy Steroid Synthesis Epimeric Purity Control
Oxaziridine reaction achieves high epimeric purity in 21-hydroxy steroid synthesis, resolving separation inefficiency and product waste.
- Selective CYP17A1 Inhibitors Reducing Off-Target Effects
Specific chemical structures target CYP17A1 while minimizing interaction with CYP21A2, reducing adverse effects.
- Cholic Acid Synthesis via Steroid Intermediates
A synthesis method for cholic acid derivatives uses borohydride reagents to reduce carbonyl groups in steroid intermediates.
- Ulipristal Acetate Synthesis via Protected Intermediates
A synthesis method for Ulipristal acetate uses protected intermediates to achieve high yield and purity.
- Obeticholic Acid Synthesis Using Plant Sterols
Replacing animal-derived cholic acid with plant sterols reduces contamination risks and lowers costs for obeticholic acid synthesis.
