Structure-activity relationship exploration of the historical biarylurea series led to the identification of novel CNS penetrant CXCR2 antagonists with nanomolar potency, favorable PK profile, and good developability potentials. More importantly, the key compound 22 showed efficacy in a cuprizone-induced demyelination model with twice daily oral administration, thereby supporting CXCR2 to be a potential therapeutic target for the treatment of demyelinating diseases such as multiple sclerosis.

Highly Optimized CNS Penetrant Inhibitors of EGFR Exon20 Insertion Mutations.

J Med Chem

January 2025

Pharmaron Beijing Co., Ltd., 6 Taihe Road, BDA, Beijing 100176, P. R. China.

Despite recent advances in the inhibition of EGFR (epidermal growth factor receptor), there remains a clinical need for new EGFR Exon20 insertion (Ex20Ins) inhibitors that spare EGFR WT. Herein, we report the discovery and optimization of two chemical series leading to ether and biaryl as potent, selective, and brain-penetrant inhibitors of Ex20Ins mutants. Building on our earlier discovery of alkyne which allowed access to CNS property space for an Ex20Ins inhibitor, we utilized structure-based design to move to lower lipophilicity and lower CL compounds while maintaining a WT selectivity margin.

Lorlatinib Induced Blindness: A Rare Entity.

Pract Radiat Oncol

January 2025

Department of Radiation Oncology, Acibadem Mehmet Ali Aydinlar University School of Medicine, Istanbul, Turkey. Electronic address:

Lorlatinib is a central nervous system (CNS) penetrant third generation tyrosine kinase inhibitor (TKI) approved for the first line management of metastatic non-small cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK) rearrangement [1] which accounts for 3-5% of NSCLC cases [2]. The most commonly reported side effects include hyperlipidemia, edema, peripheral neuropathy and CNS effects [2]. While ocular side effects such as photopsia, blurred vision, vitreous floaters and diplopia have been documented with another ALK TKI, crizotinib, there are few reports of such effects with lorlatinib [3].

Intrathecal pemetrexed in NSCLC patients with leptomeningeal metastasis.

Ecancermedicalscience

October 2024

Department of Medical Oncology, Tata Memorial Hospital, Homi Bhabha National Institute, Mumbai 400012, India.

Spread of lung cancer to the leptomeninges is rare and difficult to treat. Standard therapy comprises CNS-penetrant targeted agents with or without intrathecal chemotherapy. We performed a retrospective analysis of 16 patients with advanced NSCLC and leptomeningeal disease treated with intrathecal pemetrexed 50 mg.

Central Nervous System Metastases in Breast Cancer.

Curr Treat Options Oncol

January 2025

Breast Oncology Program, Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA, USA.

Breast cancer metastasizing to the central nervous system (CNS) encompasses two distinct entities: brain metastases involving the cerebral parenchyma and infiltration of the leptomeningeal space, i.e., leptomeningeal disease.

In multiple sclerosis (MS), microglia and macrophages within the central nervous system (CNS) play an important role in determining the balance among demyelination, neurodegeneration, and myelin repair. Phagocytic and regenerative functions of these CNS innate immune cells support remyelination, whereas chronic and maladaptive inflammatory activation promotes lesion expansion and disability, particularly in the progressive forms of MS. No currently approved drugs convincingly target microglia and macrophages within the CNS, contributing to the lack of therapies aimed at promoting remyelination and slowing disease progression for individuals with MS.
