Binding free energy analysis of galectin‐3 natural ligands and synthetic inhibitors

Article

作者: Vaissier Welborn, Valerie ; Newman, Luke

Abstract:

Galectin‐3–ligand complexes are characterized by halogen, σ‐hole bonds, hydrogen bonds, cation‐π and CH‐π interactions. Here, we model these non‐covalent interactions with the AMOEBA polarizable force field and conduct an absolute binding free energy analysis on leading galectin‐3 inhibitors. Synthetic drug molecules GB0139, GB1107, and GB1211 were estimated to have binding free energies of −4.3, −6.7, and −9.5 kcal/mol respectively. This compares to −0.3 and 1.4 kcal/mol for the natural ligands, N‐acetyllactosamine type 1 and type 2, respectively. We calculated the electric fields projected along key bonds in each ligand to further rationalize these results. We find that while the hydroxyl groups of the natural ligands interact reasonably well with residues in galectin‐3's binding pocket, structural dynamics weaken the binding pose and favor interactions with water, sometimes yielding to dissociation. In contrast, the more favorable binding energy of GB1211, leading inhibitor in clinical studies, is associated with strong and constant electric fields across the bonds investigated, suggesting a stiffer binding pose with a stabilizing σ‐hole interaction.

Development and Characterization of a High-Affinity Selective Galectin-3 Mouse Tool Compound in Mouse Models of Cancer

Article

作者: Jansson, Karl ; MacKinnon, Alison C. ; Leffler, Hakon ; Peterson, Kristoffer ; Nilsson, Ulf J. ; Gravelle, Lise ; Roper, James A. ; Zetterberg, Fredrik R. ; Wachenfeldt, Henrik von ; Pedersen, Anders ; Kahl-Knutson, Barbro ; Slack, Robert J. ; Holyer, Ian

The interest in galectin-3 as a drug target in the cancer and fibrosis space has grown during the past few years with several new classes of compounds being developed. The first orally available galectin-3 inhibitor, GB1211 (h-galectin-3 K_d = 0.025 μM), is currently in phase 2 clinical trials. Due to structural differences between human and mouse galectin-3 a significant reduction in mouse galectin-3 affinity is observed for most highly potent human galectin-3 inhibitors including GB1211 (m-galectin-3 K_d = 0.77 μM). Pharmacokinetic experiments in mouse dosing GB1211 up to 100 mg/kg results in free plasma levels below m-galectin-3 K_d, which is not comparable to the data observed in humans. To better support translation into clinical studies, a new improved mouse galectin-3 tool compound, GB2095, was developed. Dosing this new compound in in vivo syngeneic mouse models of cancer resulted in reduction of the growth of breast and melanoma cancers.

PURPOSE:

Overexpression of galectin-3, a β-galactoside-binding lectin, is associated with fibrotic diseases and cancer. Selvigaltin is an oral galectin-3 inhibitor, previously administered as a 50 mg capsule. This study aimed to evaluate the relative bioavailability and food effect of selvigaltin as a 100 mg tablet in healthy volunteers.

METHODS:

In this single-dose, randomized, three-period, crossover study (GALBA-1; NCT05747573), participants received selvigaltin as a 100 mg tablet (under fasted and fed conditions) or as two 50 mg capsules (under fasted conditions). Primary endpoints included plasma and urine pharmacokinetic (PK) parameters. Secondary endpoints were safety and tolerability.

RESULTS:

Of the 13 enrolled participants, 12 completed the study. Under fasted conditions, geometric mean maximum observed plasma concentration (C_max) and systemic exposure (AUC_0─inf) of selvigaltin were 161.0% and 84.0% higher, respectively, after administration of a tablet vs. capsules. Under fed vs. fasted conditions, geometric mean C_max of the selvigaltin tablet was 20.0% lower, whereas AUC_0─inf was unaffected. Geometric mean percentage of total dose of selvigaltin excreted in urine over 0─96 h was 30.3% and 35.9% for the tablet under fasted and fed conditions, respectively, and 14.5% for the capsules. No treatment-emergent severe or serious adverse events or study discontinuations due to a treatment-emergent adverse event were reported.

CONCLUSION:

The tablet formulation of selvigaltin displayed higher bioavailability vs. the capsule formulation, with minimal effect of food on PK. Selvigaltin was well-tolerated during all treatments. These findings warrant further clinical development of the tablet formulation of selvigaltin without specific food restrictions.

CLINICAL TRIAL REGISTRATION:

NCT05747573; February 28, 2023.

TEPMETKO Continues to Strengthens its Position as a Leading METex14 Skipping NSCLC Therapy | DelveInsight

With increasing biomarker-driven cancer treatments, TEPMETKO benefits from growing adoption in precision oncology. Competition from other MET inhibitors like TABRECTA (capmatinib) exists, but TEPMETKO's once-daily dosing and efficacy profile offer differentiation. LAS VEGAS, March 6, 2025 /PRNewswire/ -- DelveInsight's " TEPMETKO Market Size, Forecast, and Market Insight Report" highlights the details around TEPMETKO, a kinase inhibitor indicated for the treatment of adult patients with metastatic NSCLC harboring MET exon 14 skipping alterations. The report provides product descriptions, patent details, and competitor products (marketed and emerging therapies) of TEPMETKO. The report also highlights the historical and forecasted sales from 2020 to 2034 segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan]. EMD Serono's TEPMETKO (tepotinib) Overview TEPMETKO is a kinase inhibitor prescribed for adult patients with metastatic non-small cell lung cancer (NSCLC) carrying MET exon 14 skipping alterations. The active component is Tepotinib (as hydrochloride monohydrate), administered orally. Patients should be cautioned about the heightened risk of severe or fatal interstitial lung disease/pneumonitis, liver toxicity, and potential embryo-fetal toxicity, necessitating effective contraception during and shortly after treatment. Tepotinib specifically targets MET, including variants with exon 14 skipping mutations. It blocks HGF-dependent and independent MET phosphorylation, disrupting MET-driven signaling pathways. Additionally, at clinically relevant concentrations, Tepotinib inhibits melatonin 2 and imidazoline 1 receptors. In vitro studies show that it suppresses tumor cell proliferation, anchorage-independent growth, and migration of MET-dependent cancer cells. In mouse models with MET-driven tumors, including those with MET exon 14 skipping alterations, Tepotinib reduced tumor growth, sustained MET phosphorylation inhibition, and, in one case, decreased metastasis formation. The recommended dose of TEPMETKO is 450 mg taken orally once daily until disease progression or intolerable toxicity occurs. Patients should take it at the same time each day, swallowing tablets whole without chewing, crushing, or splitting them. If a dose is missed and less than eight hours remain until the next scheduled dose, patients should skip it. In cases of vomiting after taking TEPMETKO, the next dose should be taken at the usual time. Learn more about TEPMETKO projected market size for NSCLC @ TEPMETKO Market Potential Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for 81% of all diagnosed cases. Early detection greatly improves outcomes, but diagnosing NSCLC and other lung cancers is challenging because their symptoms are often mistaken for common illnesses or the long-term effects of smoking. Consequently, 80% of NSCLC cases are already at advanced stages by the time they are identified, making treatment more difficult. Around 80% of EGFR mutations in NSCLC involve either exon 19 deletions or the exon 21 L858R substitution, both of which are classified as sensitizing mutations. Until the last decade, chemotherapy was the primary treatment for advanced and metastatic lung cancer. However, this changed in 2015 with the approval of the first immune checkpoint inhibitor (ICI), KEYTRUDA (pembrolizumab), as a second-line therapy for advanced cases. This was followed by TECENTRIQ (atezolizumab) in 2016. Both therapies were later approved for first-line treatment, broadening their use to a larger patient population. In 2020, the combination of OPDIVO (nivolumab) and ipilimumab also received approval as a first-line treatment for metastatic NSCLC. According to DelveInsight, the NSCLC market size across the 7MM is projected to grow from USD 30 billion in 2024, with a substantial CAGR through 2034. This growth is largely driven by the introduction of emerging therapies during the forecast period (2025–2034).

近日，Galectin Therapeutics公司的Galectin-3抑制剂Belapectin的18周III期临床失败。 Belapectin是Galectin Therapeutics的核心管线，此次失败的适应症为MASH 引起的肝硬化门脉高压，目前该公司除了此次失败的MASH适应症，还有一项与K药联合使用治疗癌症的II期临床。目前公司唯一的希望寄托于36周的临床数据，不过目前看下来投资者显然并不买账，公司股价已经跌至1美元。与之处境相似的则是另外丹麦公司Galecto Biotech，同样是Galectin-3抑制剂，Galecto此前的核心管线GB0139也在特发性肺纤维化（IPF）这一适应症上失败。 Galectin-3抑制剂的前路看上去相当暗淡。广泛表达的靶点，不均一的靶向半乳糖凝集素-3（Galectin-3）是一种比较特殊的β-半乳糖苷结合凝集素，它与其他半乳糖凝集素的不同之处在于其单体结构，该结构包含一个C端CRD（碳水化合物识别域）、一个中间脯氨酸-甘氨酸-丙氨酸-酪氨酸重复域和一个短的N端域。由于半乳糖凝集素可以二价或多价方式结合，因此其可例如交联细胞表面糖结合物以触发细胞信号传导事件，这使得其作用机制相当复杂，它能够与细胞膜、细胞外基质、生物液体和细胞内的大量蛋白质相互作用，参与了大量的生物学和病理学事件。图：Galectin-3的结构和主要功能来源：DOI: 10.1016/j.tips.2023.06.001 Galectin-3广泛分布在心、肾、肝、肺及肠道等组织器官中。它直接参与多种炎症、纤维化和恶性疾病相关过程。（如下图所示）不过，这里同时也引来了一个问题：Galectin-3到底是疾病过程的次要参与者还是致病因素？换句话说，Galectin-3抑制剂能直接用于治疗这些疾病吗？虽然Galecto Biotech和Galectin Therapeutics的失败为这一领域笼罩了一层阴霾，但是他们的开发方向仍然值得借鉴。目前的主要开发方向是专门针对高度保守的CRD。 Galectin-3的CRD成为靶向策略核心 Gal-3的CRD在生理上适合与天然多糖配体结合。这个CRD位于蛋白质表面，暴露于溶剂中，并含有高度极性的氨基酸。天然配体如二糖乳糖和N-乙酰乳糖胺通过它们羟基基团、Gal-3的极性氨基酸和水分子之间广泛的氢键网络以及相对较弱的范德华相互作用进行结合，因此具有较低的结合亲和力。合成抑制剂最成功的尝试是基于用芳香取代基修饰半乳糖，以便与少数氨基酸形成新的强相互作用。对于这些天然配体而言，含有对这些位点具有广泛相互作用的取代基的化合物有望实现更高的选择性。在Gal-3核心结合位点中，几乎所有的强效糖基配体都靶向两个关键氨基酸残基——Arg144和Arg186。Arg144是Gal-3的独特特征，因为大多数其他凝集素在其位置有不同的残基，而Arg186在凝集素中是保守的。在Galecto此前的管线GB0139——一种二糖Gal-3抑制剂中，装饰两个半乳糖单元的芳香取代基与这些精氨酸形成强烈的π-堆积相互作用。后续开发的GB1211则与GB0139不同，这种合成单糖抑制剂只含有一个半乳糖单元，并且只涉及Arg144的π-堆积相互作用，虽然这种抑制剂只与Arg144形成π-堆积相互作用，但它通过另一种方式（糖苷异头体取代基与蛋白质骨架形成了额外的有效相互作用）增强了与Gal-3蛋白的结合力。（如下图所示）其实GB0139除了IPF以外，早先也开发过新冠适应症，但显然因为众所周知的原因放弃了。而这次失败的Belapectin（GR-MD-02）是一种来源于苹果果胶的复合药物糖聚合物，主要作用是抑制Galectin-3蛋白，不过也能显著结合结合Gal-1。实际上从早先的II期临床视角来看，用Belapectin治疗MASH本身肯定是失败的。早先的数据显示，Belapectin在一项针对NASH、肝硬化和门静脉高压患者的II期试验中，GR-MD-02在肝静脉压力或肝纤维化参数上并未显示出显著疗效。在这种绝境的情况下，Galectin专门找了无食管静脉曲张亚组进行事后分析，发现接受低剂量GR-MD-02治疗的患者门静脉压力降低，静脉曲张发展减少，才找到了MASH引起的肝硬化门脉高压这一适应症。现在18周数据未达终点，被寄予希望的36周数据能否挽救公司就尚未可知了。总结迄今为止发现的大多数Galectin-3抑制剂都存在缺乏效力或选择性的问题，同时有些Galectin-3还显著结合Gal-1。Galectin-3的广泛分布问题也是一个挑战。胞内Gal-3通常更多地与凋亡或存活途径相关。或许在癌症适应症上可能更加适合那些带有细胞穿透性的Galectin-3抑制剂，而胞外Galectin-3抑制剂更加适合炎症和纤维化疾病。然而，这种胞外和胞内的区别没有想象中那么分得开，比如说GR-MD-02既在癌症中展开适应症，又在MASH相关疾病中开展适应症。或许未来的靶向策略方向又会换到挑战N端尾巴，或者是采用抗体去靶向CRD。适应症战略或许如上海中医药大学专利申请专利CN114272382中，去治疗冠心病等心血管疾病。参考来源： Bouffette S, Botez I, De Ceuninck F.
