Paragraph 0869-0872, (2020/08/19)
A compound of formula (I) given below or a pharmaceutically acceptable salt of the compound is useful as an IDO/TDO inhibitor. Thus, the compound of formula (I) or the pharmaceutically acceptable salt of the compound can be used as, for example, a therapeutic agent for a disease or a disorder selected from tumor, infectious disease, neurodegenerative disorder, cataract, organ transplant rejection, autoimmune disease, postoperative cognitive impairment, and disease related to women's reproductive health [in the following formula (I), ring A represents an aromatic ring, an aliphatic ring, a heterocyclic ring, or a condensed ring of two or more rings selected from an aromatic ring, an aliphatic ring and a heterocyclic ring; X, R1 and R2 represent a substituent on a ring atom constituting ring A; m represents an integer of 0 to 6; X represents, for example, a halogen atom; and R1 and R2 are the same or different and are selected from, for example, the group consisting of groups of formula (a) or formula (b); and in the following formula (a) and formula (b), Y is selected from the group consisting of O, S, and Se, Z is selected from the group consisting of O, S, and Se, n represents an integer of 1 to 8, r represents an integer of 1 to 8, s represents an integer of 1 to 8, R4 represents, for example, —C(═NH)—HN2, and R6 represents, for example, a substituted or unsubstituted aryl group].

Several indenoisoquinolines have shown promise as anticancer agents in clinical trials. Incorporation of a nitrogen atom into the indenoisoquinoline scaffold offers the possibility of favorably modulating ligand-binding site interactions, physicochemical properties, and biological activities. Four series of aza-A-ring indenoisoquinolines were synthesized in which the nitrogen atom was systematically rotated through positions 1, 2, 3, and 4. The resulting compounds were tested to establish the optimal nitrogen position for topoisomerase IB (Top1) enzyme poisoning activity and cytotoxicity to human cancer cells. The 4-aza compounds were the most likely to yield derivatives with high Top1 inhibitory activity. However, the relationship between structure and cytotoxicity was more complicated since the potency was influenced strongly by the side chains on the lactam nitrogen. The most cytotoxic azaindenoisoquinolines 45 and 46 had nitrogen in the 2- or 3-positions and a 3′-dimethylaminopropyl side chain, and they had MGM GI50 values that were slightly better than the corresponding indenoisoquinoline 64.
