Solution Overview

Problem

Current CRAC channel modulators lack sufficient potency and selectivity over voltage-operated calcium channels, and existing treatments for non-small cell lung cancer (NSCLC) are limited, with a need for more targeted and less invasive therapies.

Innovation Solution

Development of compounds of formula (I) and their pharmaceutically acceptable salts, which are calcium release-activated calcium channel modulators, specifically targeting CRAC channels to treat NSCLC by inhibiting calcium influx into cancer cells expressing ORAI or STIM proteins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CRAC channel modulators are developed to treat inflammatory diseases, then anti-inflammatory efficacy is improved, but selectivity over voltage-operated calcium channels deteriorates leading to adverse events in nervous and cardiovascular systems

Engineering Contradiction:
Improveanti-inflammatory efficacyVSAvoidadverse events in nervous and cardiovascular systems
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by designing compounds with specific molecular structures (Formula I) that target CRAC channels with high selectivity. The compounds feature specific substituents (R1-R6, Ar1-Ar3, X, Y, Z) that are optimized to interact selectively with CRAC channel binding sites, ensuring anti-inflammatory efficacy while avoiding voltage-operated calcium channels in the nervous and cardiovascular systems.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs parameter changes by systematically varying chemical parameters of the compounds (different substituents, ring structures, and molecular configurations in Formula I) to optimize the balance between CRAC channel selectivity and potency. This allows tuning of the compounds to achieve therapeutic efficacy while minimizing off-target effects on other calcium channels.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If existing CRAC channel modulators are used, then some calcium channel modulation is achieved, but potency and selectivity over voltage-operated calcium channels are insufficient

3Object-generated harmful factors

If conventional cancer treatments are used for NSCLC, then cancer cell destruction is achieved, but invasiveness and side effects increase

Engineering Contradiction:
Improvecancer cell destructionVSAvoidside effects and invasiveness
Core Design Contradiction:
Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The patent applies the taking out principle by extracting and targeting a specific molecular mechanism (CRAC channel-mediated calcium influx) that is essential for cancer cell survival and proliferation. By selectively inhibiting this specific pathway in cancer cells expressing ORAI or STIM proteins, the treatment achieves cancer cell destruction while avoiding the non-specific toxicity and invasiveness of conventional chemotherapy approaches.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs the intermediary principle by using CRAC channel modulators as a mediator to disrupt the calcium signaling pathway in cancer cells. The compounds act as intermediaries that block the interaction between ORAI channels and STIM proteins, thereby preventing calcium influx and inducing cancer cell death through apoptosis, while sparing normal cells that do not rely as heavily on this pathway.

Inventive Principle:
Principle #24Intermediary (Mediator)
