Compositions and methods for treatment of central nervous system tumors

Compounds, pharmaceutical compositions, and methods for treating cancer, in particular brain cancer, are provided, including amphiphilic fatty acid/alcohol ethers (AIPs) comprising endocannabinoid and FABP motifs covalently linked to a beta-adrenoreceptor antagonist motif in one molecule. The invention includes methods for inhibiting growth of brain cancer cells by contacting the compound(s) with brain cancer cells. The invention provides a method for treating both brain cancer and brain cancer metastases, and for suppression of regrowth of brain cancer cells after radiation, surgical treatment, or chemotherapy of brain cancer. The invention also comprises an optimized chemical synthesis of the AIP compounds and methods of using the compounds, alone or in combination with another agent, for suppressing the growth of brain cancer cells, and enhancing survival of normal CNS cells, or improving recuperation from radiation, surgical or chemotherapy.

EPOXIDE FUNCTIONALIZED POLYAROMATIC FEEDSTOCK AND POLYMERS DERIVED THEREFROM
20220289700 · 2022-09-15 ·

Epoxide functionalized polyaromatic feedstocks and processes for their preparation are described. The processes involve functionalizing polyaromatic hydrocarbon molecules and/or polyheterocyclic molecules present in petroleum or petrochemical streams with epoxide. The epoxide functionalized poly aromatic feedstock can be further treated so as to effect oligomerization or polymerization. The oligomers or polymers may be thermoplastic or thermoset materials and may find use in, for example, infrastructure applications, composites, fillers, fire retardants and 3-D printing materials.
