T-cell acute lymphoblastic leukemia (T-ALL) is a hardly curable disease with a high relapse rate. 20 analogs were synthesized based on the structures of two kinds of fungi-derived polyenylpyrrole products (rumbrin (1) and auxarconjugatin-B (2)) to suppress the growth of T-ALL-derived cell line CCRF-CEM and tested for growth-inhibiting activity. The octatetraenylpyrrole analog gave an IC50 of 0.27 μM in CCRF-CEM cells, while it did not affect Burkitt lymphoma-derived cell line Raji and the cervical cancer cell line HeLa, or the oral cancer cell line HSC-3 (IC50 > 10 μM). This compound will be a promising compound for developing T-ALL-specific drugs.
2-(1-dimethylamino-2-cyanoethyl) pyrrole derivative and synthesis method thereof

Paragraph 0103-0107, (2020/07/08)
The invention discloses a 2-(1-dimethylamino-2-cyanoethyl)pyrrole derivative and a synthesis method thereof. According to the method, a pyrrole derivative which is cheap, easy to obtain and diverse instructure is used as a raw material and is subjected to a Friedel-Crafts reaction with 3-dimethylaminoacrylonitrile in the presence of acid to synthesize the 2-(1-dimethylamino-2-cyanoethyl) pyrrolederivative. The method has the advantages of cheap and accessible raw materials, low toxicity, mild synthesis reaction conditions and high efficiency, and is simple to operate.

α-Diazo-β-ketoesters and α-diazoketones derived from 2-pyrrolylacetic, 2-pyrrolylpropionic, 3-indolylacetic and 3-indolylpropionic acids afforded carbenoid derived cyclization products on treatment with catalytic rhodium(II) acetate.

Measurement of 3JCO,H coupling constants provides an unambiguous procedure for the configurational analysis of substituted 2- and 3-arylpropenoic esters and of E- and Z-2-arylbut-2-en-1,4-dioates, even when only one of the isomers is available for analysis.An analogous procedure can also be used for the configurational analysis of 3-arylpropenonitriles and of 4-arylbut-3-en-2-ones.
