Current HMN‑384 designs focus on inference, with weights programmed off‑chip. The next generation aims to support online spike‑timing‑dependent plasticity (STDP) and gradient‑based learning directly in the analog domain, enabling continual adaptation without external reprogramming.
Through structure-based drug design (SBDD) utilizing the crystal structure of the CDK11/Cyclin L complex, we synthesized a series of aminopyrimidine derivatives optimized for interaction with the unique "gatekeeper" residue of CDK11. This effort yielded HMN-384 ((2R)-2-[[4-[(3-chlorophenyl)amino]-5-(trifluoromethyl)pyrimidin-2-yl]amino]-3-methylbutan-1-ol). HMN-384
Biochemical kinase assays revealed that HMN-384 potently inhibits CDK11 kinase activity with an IC50 of 4.2 nM. To assess selectivity, HMN-384 was screened against a panel of 468 kinases using the KinomeScan assay at a concentration of 1 µM. HMN-384 demonstrated exquisite selectivity, with a selectivity score (S(35)) of 0.01. Notably, HMN-384 showed >1,000-fold selectivity over CDK4 and CDK6, and >500-fold selectivity over CDK9. This distinct selectivity profile suggests that HMN-384 avoids the neutropenia and gastrointestinal toxicity associated with CDK4/6 and CDK9 inhibition, respectively.

HMN‑384: A Vision of the Next‑Generation Modular Hyper‑Neural Processor
Abstract
The rapid convergence of artificial intelligence, edge computing, and neuromorphic engineering has created a fertile ground for a new class of processors that blend the flexibility of digital logic with the efficiency of brain‑inspired architectures. Among the most ambitious proposals emerging from this landscape is the HMN‑384, a modular hyper‑neural processor designed to deliver petaflop‑scale inference at sub‑watt power budgets. This essay examines the conceptual underpinnings of the HMN‑384, its architectural innovations, potential application domains, and the broader societal implications of deploying such a technology at scale.
In autonomous drones, the HMN‑384 can run a full event‑driven visual pipeline—spiking front‑end, spiking optical flow, and a transformer‑style attention module for obstacle avoidance—while staying below 2 W. The low latency (< 5 ms end‑to‑end) enables rapid reaction to dynamic environments, and the event‑driven nature dramatically reduces data movement compared with frame‑based pipelines.
