New drug research and development system and method based on distributed pulsation calculation architecture

Abstract

The invention discloses a new drug research and development system and method based on a distributed pulsation calculation architecture, and belongs to the technical field of computer-aided drug design and artificial intelligence. The system includes a central scheduling platform, a plurality of pharmacological entity (PE) computing modules, and a pulsatile display collaborative network connecting them. According to the network, PE modules are organized into calculation groups and calculation units according to a three-three system principle, so that the system has module independence and cooperative combat capability. The system supports various cooperation modes of an adder, a multiplier, a power device and a register, and can be dynamically reconfigured to adapt to different research and development tasks. The system is also integrated with endogenous security defense modules distributed at all levels. The method comprises the steps of receiving and decomposing tasks; the PE is dynamically scheduled, and the groups or the units perform cooperative calculation according to a specified mode; real-time safety monitoring is realized; and integrating and outputting decision data. The problems of centralization bottleneck and framework stiffness of the existing AI pharmaceutical technology are solved, and the efficiency, the success rate, the safety and the knowledge inheritance capacity of new drug research and development are remarkably improved.

Description

Technical Field

[0001] This invention relates to the fields of computer-aided drug design and artificial intelligence, and in particular to a new drug development system and method that employs a distributed, modular, and reconfigurable computing architecture and possesses an intrinsic security defense mechanism. Background Technology

[0002] Artificial intelligence technology has deeply penetrated all aspects of new drug development, such as target discovery, compound screening, and optimization. Companies like Ingenic Semiconductor, XtalPi, and Xaira Therapeutics are pioneers in this field.

[0003] However, existing AI-driven drug development platforms generally suffer from the following technical shortcomings:

[0004] 1. Bottlenecks of centralized architecture: This architecture often employs a single, large pre-trained model. This architecture carries the risk of a single point of failure; errors or biases in one layer of the model can propagate to the entire system, leading to unreliable output. Furthermore, when handling complex multi-task tasks, intense competition for computing resources results in low efficiency.

[0005] 2. Rigid task adaptability: Once the model is trained, its structure and function are relatively fixed. When the research and development task shifts from "massive initial screening" to "precise optimization", the system is difficult to dynamically adjust its computational paradigm, requiring retraining or deployment of new models, which is costly and inflexible.

[0006] 3. Insufficient security and robustness: AI models are vulnerable to adversarial attacks and data poisoning attacks. Existing technologies mostly set up firewalls at the system perimeter, lacking mechanisms for real-time, multi-layered security monitoring and self-healing within the computing process.

[0007] 4. Knowledge silos and inefficient iteration: Valuable process data and optimization strategies generated from different projects and stages are difficult to be structured, accumulated and reused, resulting in each new drug development project starting almost from scratch.

[0008] Therefore, there is an urgent need in this field for a new drug development computing architecture that can overcome the above-mentioned shortcomings and has greater flexibility, security, efficiency and continuous learning capabilities. Summary of the Invention

[0009] The purpose of this invention is to provide a new drug development system and method based on a distributed pulsed computing architecture to solve the problems of centralized bottlenecks, rigid architecture, weak security, and difficulty in knowledge transfer in existing AI drug development technologies.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] In a first aspect, the present invention provides a new drug development system based on a distributed pulsed computing architecture, comprising:

[0012] 1. System Architecture Overview

[0013] This system adopts a cloud-native architecture and is built on the Kubernetes container orchestration platform, and includes the following core components:

[0014] Central dispatch platform (based on Apache Airflow)

[0015] Pharmacology Entity Computation Module (Docker Container Cluster)

[0016] Pulsating Display-Based Collaborative Network (based on Kubernetes Service Mesh)

[0017] Intrinsic security defense system (multi-layered security monitoring + blockchain)

[0018] Service Registry Discovery Center (Consul)

[0019] Monitoring and alarm system (Prometheus + Alertmanager)

[0020] Distributed storage system (AWS S3 compatible interface)

[0021] 2. Specific Implementation of the Pharmacology Entity Calculation Module**

[0022] 2.1 PE Technical Specifications

[0023] Each PE is an independent Docker container, with the following specific configuration:
