Homoarcyriaflavin: Synthesis of Ring-Expanded Arcyriaflavin Analogues

The construction of the ring-expanded carbazole system, forming arcyriaflavin homologues, is efficiently accomplished by the reaction of 2,2?-bridged bis-indoles with 3,4-dibromo-2,5-dihydro-1H-2,5-pyrroledione derivatives under Grignard conditions. A ring size of up to nine members in the central ring is achievable. Substitutions either at the indole system or at the imide-N are also possible. The conformation of homoarcyriaflavins as a cross-link between the rigid arcyriaflavins and the flexible arcyriarubins was investigated by NMR, X-ray, and semiempiric quantum chemical calculation methods.

One new alkaloid from Chelidonium majus L

One new alkaloid, together with 10 known compounds were isolated from the aerial parts of Chelidonium majus L. by repeated silica gel column chromatography. Their chemical structures were elucidated on the basis of physicochemical and spectroscopic data. Among them, 6-acetonyldihydrochelerythrine (4), 6-acetonyldihydrosanguinarine (5), 6-ketenesanguinarine (6), demethylchelerythrine (7) and demethylsanguinarine (11) were isolated for the first time from this plant. Compound 6 was identified as a new compound. These compounds were screened for cytotoxicity against human non-small lung carcinoma (H1299), breast cancer (MCF-7) and liver cancer (SMMC-7721). In a series of cytotoxic tests, compounds 9 and 10 displayed potent cytotoxic activity against H1299, MCF-7 and SMMC-7721, with the IC50values of 8.16-35.25 mug/mL.

Thermally cleavable surfactants

Two new surfactant molecules are reported which contain thermally labile Diels-Alder adducts connecting the polar and non-polar sections of each molecule. The two surfactants possess identical non-polar dodecyl tail segments but exhibit different polar headgroups. The surfactants become soluble in water when anionic salts are formed through the deprotonation of the surfactant headgroups by the addition of potassium hydroxide. When either surfactant is exposed to temperature above about 60 C., the retro Diels-Alder reaction occurs, yielding hydrophilic and hydrophobic fragments and the aqueous solutions of the surfactants subsequently exhibit loss of all surface-active behavior.

Total syntheses of the slime mold alkaloid arcyriacyanin A

Arcyriacyanin A (1) has been synthesized by three different routes. In the first synthesis the bisbromomagnesium salt of 2,4′-biindole (5) was treated with dibromomaleimide (6) to yield arcyriacyanin A (1). The second approach used an intramolecular Hock reaction for the cyclization of a 4-(triflyloxy)arcyriarubin 8 to N-methylarcyriacyanin A (2). Thirdly, compound 2 was obtained by a domino Heck reaction between 3-bromo-4-[1(tert-butoxycarbonyl)indol-3-yl]-1-methylmaleimide (9) and 4-bromoindole (10). The N-methyl derivative 2 could be transformed into arcyriacyanin A (1) by standard methods.

NEOADJUVANT USE OF ANTIBODY-DRUG CONJUGATES

The present invention concerns improved methods and compositions for neoadjuvant use of antibody-drug conjugates (ADCs) in cancer therapy, preferably ADCs comprising an anthracycline or camptothecin, more preferably SN-38 or pro-2-pyrrolinodoxorubicin (P2PDox). The ADC is administered as a neoadjuvant, prior to treatment with a standard anti-cancer therapy such as surgery, radiation therapy, chemotherapy, or immunotherapy. Neoadjuvant use of the ADC substantially improves the efficacy of standard anti-cancer therapy and may debulk a primary tumor or eliminate micrometasteses. In most preferred embodiments, neoadjuvant ADC in combination with a standard anti-cancer therapy is successful in treating cancers that are resistant to standard treatments, such as triple-negative breast cancer (TNBC).
