简介

Atypical MAPK protein that regulates several process such as autophagy, ciliogenesis, protein trafficking/secretion and genome integrity, in a kinase activity-dependent manner (PubMed:22948227, PubMed:24618899, PubMed:29021280, PubMed:21847093, PubMed:20733054). Controls both, basal and starvation-induced autophagy throught its interaction with GABARAP, MAP1LC3B and GABARAPL1 leading to autophagosome formation, SQSTM1 degradation and reduced MAP1LC3B inhibitory phosphorylation (PubMed:22948227). Regulates primary cilium formation and the localization of ciliary proteins involved in cilium structure, transport, and signaling (PubMed:29021280). Prevents the relocation of the sugar-adding enzymes from the Golgi to the endoplasmic reticulum, thereby restricting the production of sugar-coated proteins (PubMed:24618899). Upon amino-acid starvation, mediates transitional endoplasmic reticulum site disassembly and inhibition of secretion (PubMed:21847093). Binds to chromatin leading to MAPK15 activation and interaction with PCNA, that which protects genomic integrity by inhibiting MDM2-mediated degradation of PCNA (PubMed:20733054). Regulates DA transporter (DAT) activity and protein expression via activation of RhoA (PubMed:28842414). In response to H(2)O(2) treatment phosphorylates ELAVL1, thus preventing it from binding to the PDCD4 3'UTR and rendering the PDCD4 mRNA accessible to miR-21 and leading to its degradation and loss of protein expression (PubMed:26595526). Also functions in a kinase activity-independent manner as a negative regulator of growth (By similarity). Phosphorylates in vitro FOS and MBP (PubMed:11875070, PubMed:16484222, PubMed:20638370, PubMed:19166846). During oocyte maturation, plays a key role in the microtubule organization and meiotic cell cycle progression in oocytes, fertilized eggs, and early embryos (By similarity). Interacts with ESRRA promoting its re-localization from the nucleus to the cytoplasm and then prevents its transcriptional activity (PubMed:21190936).

In this study, it was aimed to determine the effect of sinapic acid (SNP), a polyphenol with antioxidant, anti-inflammatory and antibacterial properties, on testicular damage caused by vancomycin (VCM), a widely used antibiotic against gram positive bacteria. A total of 35 male Sprague Dawley rats were used in the study, divided into five groups: control, VCM, SNP, VCM + SNP 10, and VCM + SNP 20. Following a week of oral administration, the rats were euthanized under sevoflurane anesthesia. While the VCM group had a significant increase in MDA levels, the SNP administration inhibited the increase in MDA levels. VCM led to a significant decrease in GSH levels, SOD, CAT, and GPx activity in the testicular tissue of rats, while SNP administration increased these antioxidant levels. SNP administration decreased the mRNA expression levels of VCM induced Nrf-2, HO-1, and NQO1 in testicular tissue while increasing the levels of MAPK14, MAPK15, JNK, P53, Apaf-1, Caspase-3, Caspase-6, Caspase-9, and Beclin-1 mRNA transcript levels. The VCM group showed a significant increase in Bax and NF-κB levels in testicular tissue, while Bcl-2 levels decreased. VCM significantly decreased sperm motility and increased the percentage of damaged sperm in rats. Histopathological results revealed that VCM caused disruption of basement membranes and disorganization of seminiferous tubules, but SNP administration preserved testicular histology. As a result, VCM increased oxidative stress, apoptosis, and autophagy in the testicular tissue of rats, altered testicular histopathology, and decreased sperm quality, while SNP decreased these effects.

Mercuric chloride (HgCl₂) is a heavy metal that is toxic to the human body. Carvacrol (CAR) is a flavonoid found naturally in plants and has many biological and pharmacological activities including anti-inflammatory, antioxidant, and anticancer activities. This study aimed to investigate the efficacy of CAR in HgCl₂-induced testicular tissue damage. HgCl₂ was administered intraperitoneally at a dose of 1.23 mg/kg body weight alone or in combination with orally administered CAR (25 mg/kg and 50 mg/kg body weight) for 7 days. Biochemical and histological methods were used to investigate oxidative stress, inflammation, apoptosis, and autophagy pathways in testicular tissue. CAR treatment increased HgCl₂-induced decreased antioxidant enzyme (SOD, CAT, and GPx) activities and GSH levels. In addition, CAR reduced MDA levels, a marker of lipid peroxidation. CAR decreased the levels of inflammatory mediators NF-κB, TNF-α, IL-1β, COX-2, iNOS, MAPK14, MAPK15, and JNK. The increases in apoptotic Bax and Caspase-3 with HgCl₂ exposure decreased with CAR, while the decreased antiapoptotic Bcl-2 level increased. CAR reduced HgCl₂-induced autophagy damage by increasing Beclin-1, LC3A, and LC3B levels. Overall, the data from this study suggested that testicular tissue damage associated with HgCl₂ toxicity can be mitigated by CAR administration.

OBJECTIVELong-term exposure to arsenic has been linked to several illnesses, including hypertension, diabetes, hepatic and renal diseases and cardiovascular malfunction. The aim of the current investigation was to determine whether zingerone (ZN) could shield rats against the hepatotoxicity that sodium arsenite (SA) causes.METHODSThe following five groups of thirty-five male Sprague Dawley rats were created: I) Control; received normal saline, II) ZN; received ZN, III) SA; received SA, IV) SA + ZN 25; received 10 mg/kg body weight SA + 25 mg/kg body weight ZN, and V) SA + ZN 50; received 10 mg/kg body weight SA + 50 mg/kg body weight ZN. The experiment lasted 14 days, and the rats were sacrificed on the 15th day. While oxidative stress parameters were studied by spectrophotometric method, apoptosis, inflammation and endoplasmic reticulum stress parameters were measured by RT-PCR method.RESULTSThe SA disrupted the histological architecture and integrity of the liver and enhanced oxidative damage by lowering antioxidant enzyme activity, such as those of glutathione peroxidase (GPx), catalase (CAT), superoxide dismutase (SOD), glutathione (GSH) level and increasing malondialdehyde (MDA) level in the liver tissue. Additionally, SA increased the mRNA transcript levels of Bcl2 associated x (Bax), caspases (-3, -6, -9), apoptotic protease-activating factor 1 (Apaf-1), p53, tumor necrosis factor-α (TNF-α), nuclear factor kappa B (NF-κB), interleukin-1β (IL-1β), interleukin-6 (IL-6), c-Jun NH2-terminal kinase (JNK), mitogen-activated protein kinase 14 (MAPK14), MAPK15, receptor for advanced glycation endproducts (RAGE) and nod-like receptor family pyrin domain-containing 3 (NLRP3) in the liver tissue. Also produced endoplasmic reticulum stress by raising the mRNA transcript levels of activating transcription factor 6 (ATF-6), protein kinase RNA-like ER kinase (PERK), inositol-requiring enzyme 1 (IRE1), and glucose-regulated protein 78 (GRP-78). These factors together led to inflammation, apoptosis, and endoplasmic reticulum stress. On the other hand, liver tissue treated with ZN at doses of 25 and 50 mg/kg showed significant improvement in oxidative stress, inflammation, apoptosis and endoplasmic reticulum stress.CONCLUSIONSOverall, the study's data suggest that administering ZN may be able to lessen the liver damage caused by SA toxicity.

德琪医药ATG-017获FDA批准I期临床，治疗晚期实体瘤！

2022年11月1日，德琪医药宣布，ERK1/2小分子抑制剂ATG-017的1期临床试验申请（IND）已获美国食品药品监督管理局（FDA）批准，用于治疗晚期实体瘤。随后，德琪医药将在美国启动1期ERASER研究的联合治疗部分，以评估ATG-017联合纳武利尤单抗用于治疗晚期实体瘤的安全性、药代动力学和初步疗效。来源：德琪医药官网该项由德琪医药与百时美施贵宝合作的旨在评估ATG-017联合纳武利尤单抗的临床合作是基于已有的临床前数据，其中部分数据已于2021年11月在第36届肿瘤免疫治疗学会（SITC）年会及会前环节中公布。数据显示，ERK1/2抑制剂（ATG-017）联合免疫检查点抑制剂（ICI，PD-L1单抗，阿特朱单抗）发挥了协同作用，在ICI耐药的小鼠体内模型中产生了更好的疗效，达到肿瘤由“冷”至“热”的转化。此外，据Clinicaltrails.gov网站信息显示，2020年3月12日德琪医药登记了一项临床研究（NCT04305249），这是一项开放、多中心I期研究（代号：ERASER），主要评估ATG-107单药治疗晚期实体瘤和恶性血液瘤患者的安全性、药代动力学和初步疗效。目前该单药治疗爬坡正在澳大利亚顺利开展，并将继续参与联合治疗部分的研究。除澳大利亚和美国外，德琪医药还计划在中国开展这项国际多中心研究。目前在药物临床试验登记与信息公示平台暂未检索到ATG-017的临床试验登记号。关于ERK1/2细胞外信号调节蛋白激酶1/2（ERK1/2）是一类丝氨酸/苏氨酸蛋白激酶，是MEK1/2唯一已知的底物，位于RAS-RAF-MEK-ERK（MAPK）通路的下游，其作用是作为RAS-MAPK信号转导级联通路的终端激酶。该级联通路调节细胞增殖等多种细胞进程。RAS-MAPK通路失调发于30%以上的癌症患者，最为常见的变化为多个肿瘤类型的RAS或BRAF基因突变。ERK抑制剂可同时靶向RAS和BRAF突变疾病。目前，已有多种靶向RAS、RAF和MEK的小分子抑制剂被批准用于癌症治疗，然后，长期治疗中产生的获得性耐药降低了这些药物的疗效。近年来，选择性抑制ERK1/2被认为是一种潜在的癌症治疗策略，它不仅可以有效阻断MAPK通路，还可以克服RAS、RAF和MEK上游突变引起的耐药性。ERK1/2的关键调控通路来源：Fu et al. J Med Chem. 2022, 65(20): 13561-13573关于ATG-017ATG-017（AZD0364，Tizaterkib）是一款作用于细胞外信号调节激酶1和2（ERK1/2）的可逆型、ATP竞争性的强效、选择性口服小分子抑制剂，是以阿斯利康已有的先导化合物7为基础，进行构效关系（SAR）优化后得到的激酶选择性更强、药代动力学性质更佳的ATG-107。ATG-107对ERK2的IC50值为0.6 nM，水溶性468 uM，在体外大鼠和人肝细胞中均较稳定，渗透性（Caco-2 Papp）为26.7*10-6 cm/s，是高渗化合物，大鼠和犬灌胃给药后的生物利用度分别为30%和100%，具有较好的药代动力学性质。据文献报道，基于临床前试验数据推测的人体清除率范围是0.5-6 ml/min/kg，预测人体首次给药剂量为20-110 mg，一天两次。根据此前研究报道，在多个体内异种移植瘤模型中，ATG-017展现了对ERK1/2依赖性信号生物标志物的剂量和时间依赖性调节，从而使得BRAF敏感型和KRAS突变敏感型异种移植瘤的肿瘤消退。此外，ATG-01与MEK1/2抑制剂selumetinib (AZD6244和ARRY142886)的联合给药可以更深入、更持久地抑制RAS/MAPK信号通路，这是单药治疗无法实现的。ATG-017和selumetinib联合给药也会在KRAS突变的异种移植瘤模型中出现显著的肿瘤消退。因此，ERK1/2抑制剂和MEK1/2抑制剂的联合给药是靶向KRAS突变肿瘤的一种可行的临床方法。体外研究中，ATG-017对MAPK信号通路的直接下游底物具有高细胞活性（如在BRAFV600E突变的A375细胞中，抑制phospho-p90RSK，IC50= 5.73 nM）。ATG-107浓度为1 uM时，在包含353种激酶的激酶库中对其中9种激酶（MEK1, COT, BRAF, MEK2, c-RAF, ERK7, CDK2, CDK5 and ARK5）的抑制作用大于50%。A: AZD0364（ATG-017）的结构式B: AZD0364（ATG-017）与ERK2的结合位点来源：Vikki Flemington. et al. Mol Cancer Ther. 2021, 20(2): 238-249.“RAS/MAPK通路是癌症发生的一个重要驱动因素。ATG-017靶向ERK1/2不仅能阻止肿瘤细胞的生长，还能与其他MAPK激酶抑制剂协同作用，更有效地阻断RAS-MAPK信号传导，同时克服患者对RAF及MEK抑制剂产生耐药。”德琪医药创始人、董事长兼首席执行官梅建明博士说，“我们认为ATG-017拥有强大的临床潜力和广阔的应用前景。不单是针对实体瘤与血液瘤的单药疗法，德琪团队也正深入挖掘ATG-017与公司其他在研产品的协同性，以期获得更好的抗癌效果。”权益合作ATG-017由阿斯利康公司发现及早期研究，德琪医药拥有开发、生产及商业化该产品的全球独家权益。2019年11月6日，德琪医药宣布与英国阿斯利康公司达成一项全球性的独家授权协议，推进创新药物ATG-017（AZD0364）在全球的临床开发，生产和商业化。阿斯利康公司在此次交易前已终止了全球范围内其他关于ATG-017的授权协议，包括与辅仁药业的授权协议。2021年12月13日，德琪医药宣布与百时美施贵宝公司达成了一项临床合作协议，将共同开展一项旨在评估ATG-017联合百时美施贵宝的PD-1检查点抑制剂欧狄沃®（纳武利尤单抗）用于治疗晚期实体瘤的安全性、药代动力学和初步疗效的开放性1/2期临床研究。根据该协议，德琪医药将负责该临床试验的开展，并提供资金支持。百时美施贵宝公司将提供联合疗法的剂量爬坡和剂量扩展研究中所需的欧狄沃®。竞争格局目前关于靶向ERK药物的研究尚处在早期临床阶段，全球范围内仅有BioMed Valley Discoveries公司的BVD-523、Merck公司的MK-8353与Genentech的GDC-0994披露临床数据。全球范围内到目前为止没尚无任何一款已获批上市的ERK1/2抑制剂。BVD-523BVD-523（Ulixertinib，VRT752271）是由BioMed Valley Discoveries公司研发的可逆型、ATP竞争性ERK1/2抑制剂，其对ERK1的Ki < 0. 3 nM，对ERK2的Ki = 0. 04 nM。2017年12月15日，Cancer Discov杂志公布了ERK1/2抑制剂BVD-523的I期临床试验（NCT01781429）数据。结果提示2期临床试验推荐剂量为600 mg BID给药，最常见治疗相关不良反应包括腹泻(48%)、疲劳(42%)、恶心(41%)和痤疮性皮炎(31%)。在部分患者中，BVD-523治疗确实获得了部分缓解或疾病稳定状态，且疗效似不受肿瘤类型的影响。BVD-523具有可接受的安全性和良好的药代动力学性质。MK-8353MK-8353是通过改善SCH772984的PK 而优化得到的（ERK1：IC50= 20 nM；ERK2：IC50 = 7 nM）。SCH772984是由Merck公司通过基于亲和力的质谱高通量平台筛选、鉴定并通过结构优化得到的ATP 竞争性的ERK1/2抑制剂。2018年2月22日，JCI Insight杂志公布了ERK1/2抑制剂MK-8353的I期临床试验（NCT01358331）数据。在所有剂量中MK-8353总体安全性和耐受性良好，并且未发生严重不良事件（SAE）。在400毫克和800毫克剂量组中观察到剂量限制性毒性。在可评价治疗缓解的15名晚期实体瘤患者中，3名患者具有部分缓解，他们全部患有BRAFV600突变型黑色素瘤。GDC-0994GDC-0994是由Genentech公司研发的口服的选择性ERK1/2抑制剂，其对ERK1和ERK2的IC50分别为6. 1和3. 1 nmol/L。2020年3月15日，CCR杂志公布了新型ERK1/2抑制剂GDC-0994的I期临床试验（NCT01875705）数据。47名跨癌种的难治性晚期实体瘤患者，接受了该药物治疗。20名患者在接受治疗前后，均进行PET-CT检测，从PET-CT上可以反应肿瘤的代谢活性，其中11名患者肿瘤代谢活性明显下降，其中就包括4名胰腺癌患者。而从普通CT上看，45名患者中有15人肿瘤控制稳定。最难能可贵的是：2名BRAF突变的难治性肠癌患者，接受该药物治疗后，肿瘤明显缩小，缩小幅度超过30%，给这种极端难治的晚期肠癌患者带来了新的希望。CC-90003CC-90003是不可逆的共价结合的选择性ERK1/2 抑制剂，主要用于治疗KRAS突变的肿瘤，2015年进入1期临床研究。但是由于在1期临床试验中，其最大耐受剂量（MTD）结果不令人满意，目前已经暂停了其临床试验（NCT02313012）。此外，据药渡数据的不完全统计，目前临床阶段上二十多款ERK1/2抑制剂药物正在推进中，进展最快的项目也仅处于2期阶段。国内进展最快的是海和医药的BPI-27336、和记黄埔的HMPL-295S1和捷思英达的JSI-1187，相关ERK1/2抑制剂所处临床阶段多为1期。德琪医药的ATG-017因拥有同类最佳的潜力，且该品种还与免疫检查点抑制剂和其它靶向 RAS/MAPK通路的抑制剂具有很高的联用潜力，有望在竞争中先拔头筹。参考来源各公司官网；Leilei Fu. et al.
