Menin–MLL Interaction Inhibitors for MLL-Fusion Leukemia

Solution Overview

Problem

Current therapies for leukemias involving MLL fusion proteins, such as acute myeloblastic leukemia (AML) and acute lymphoblastic leukemia (ALL), have a dismal prognosis, with less than a 40% five-year survival rate, necessitating a novel therapeutic strategy to target the interaction between menin and MLL fusion proteins.

Innovation Solution

Development of compounds that non-covalently or covalently bind to menin to inhibit its interaction with MLL1, MLL2, and MLL-fusion oncoproteins, thereby disrupting the oncogenic activity of these proteins.

1Reliability

If current therapies are used for leukemias involving MLL fusion proteins, then treatment is provided, but the prognosis remains dismal with less than 40% five-year survival rate

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and targets the critical menin-MLL interaction interface to disrupt the oncogenic activity. By developing compounds that specifically bind to menin and prevent its interaction with MLL fusion proteins, the harmful oncogenic function is separated and eliminated while maintaining normal cellular functions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces small molecule compounds as intermediary agents that bind to menin and block its interaction with MLL fusion proteins. These compounds act as mediators that disrupt the harmful protein-protein interaction without directly targeting the MLL fusion proteins themselves, thereby achieving therapeutic effect.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If menin-MLL interaction is inhibited, then oncogenic activity is disrupted, but new therapeutic compounds must be developed

Engineering Contradiction:
Core Design Contradiction:
Object-generated harmful factorsVSEase of manufacture

Solution Approach 1:

The patent employs structure-activity relationship (SAR) analysis to systematically modify molecular parameters of compounds binding to menin. By changing structural parameters such as functional groups, molecular size, and binding affinity, the patent optimizes the compounds for effective menin-MLL interaction inhibition while considering manufacturability and pharmacological properties.
