Therapy Description

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

Drug Name Trade Name Synonyms Drug Classes Drug Description
LTT462 LTT 462 ERK Inhibitor (pan) 18 LTT462 inhibits ERK, resulting in decreased downstream signaling, and reduced ERK-dependent proliferation and survival of tumor cells (NCI Drug Dictionary).
LXH 254 LXH254|LXH-254 BRAF Inhibitor 21 CRAF Inhibitor 11 LXH 254 is a RAF inhibitor that selectively inhibits monomeric and dimerized BRAF and CRAF, which may lead to anti-tumor activity in RAF-mutant tumors and better tolerability (AACR Annual Meeting 2019, Abstract LB-114, PMID: 31059256).
