Paragraph 1523-1525; 1531-1533, (2021/08/19)
The invention relates to a spiro derivative, a preparation method thereof and application of the spiro derivative in medicine. Specifically, the invention relates to the spiro derivative shown in a general formula (I), the preparation method thereof, a pharmaceutical composition containing the spiro derivative and application of the spiro derivative as a therapeutic agent, especially application of the spiro derivative as an RAF inhibitor and application of the spiro derivative in preparation of drugs for treating or preventing various diseases (including cancers) related to over-expression RAF activity.

As part of an ongoing effort in NS5A inhibition at Merck we now describe our efforts for introducing substitution around the tetracyclic indole core of MK-8742. Fluoro substitution on the core combined with the fluoro substitutions on the proline ring improved the potency against GT1a Y93H significantly. However, no improvement on GT2b potency was achieved. Limiting the fluoro substitution to C-1 of the tetracyclic indole core had a positive impact on the potency against the resistance associated variants, such as GT1a Y93H and GT2b, and the PK profile as well. Compounds, such as 62, with reduced potency shifts between wild type GT1a to GT2b, GT1a Y93H, and GT1a L31V were identified.
