HSP (HSP90)
SNX-2112, a Selective Hsp90 Inhibitor, Potently Inhibits Tumor Cell Growth, Angiogenesis, and Osteoclastogenesis in Multiple Myeloma and Other Hematologic Tumors by Abrogating Signaling via Akt and ERK
98 views | Apr 19 2020
Yutaka Okawa et al. provided the framework for clinical studies of SNX-2112 to improve patient outcome in MM and other hematologic malignancies. [Read the Full Post]
A Phase I Study of PF-04929113 (SNX-5422), an Orally Bioavailable Heat Shock Protein 90 Inhibitor, in Patients With Refractory Solid Tumor Malignancies and Lymphomas
91 views | Apr 19 2020
Arun Rajan et al. showed that PF-04929113 administered orally twice a week is well tolerated and inhibits its intended target Hsp90. No objective responses were seen, but long-lasting stabilizations were obtained. Although no clinically significant drug-related ocular toxicity was seen in this study, the development of PF-04929113 has been discontinued because of ocular toxicity seen in animal models and in a separate phase I study.

The novel HSP90 inhibitor STA-9090 exhibits activity against Kit-dependent and -independent malignant mast cell tumors
142 views | Mar 15 2020
Lin TY et al. showed that STA-9090 exhibits broad activity against mast cells expressing WT or mutant Kit, suggesting it may be an effective agent in the clinical setting against mast cell malignancies. [Read the Full Post]
Ganetespib limits ciliation and cystogenesis in autosomal-dominant polycystic kidney disease (ADPKD)
154 views | Mar 15 2020
Nikonova AS et al. identified a new biologic activity for HSP90 and support a cilia-based mechanism for cyst repression.-Nikonova, A. S., Deneka, A. Y., Kiseleva, A. A., Korobeynikov, V., Gaponova, A., Serebriiskii, I. G., Kopp, M. C., Hensley, H. H., Seeger-Nukpezah, T. N., Somlo, S., Proia, D. A., Golemis, E. A. Ganetespib limits ciliation and cystogenesis in autosomal-dominant polycystic kidney disease (ADPKD). [Read the Full Post]
17-AAG inhibits vemurafenib-associated MAP kinase activation and is synergistic with cellular immunotherapy in a murine melanoma model
202 views | Jan 08 2020
Joshi SS et al. indicated their sdudies support a role for 17-AAG and HSP90 inhibition in enhancing cellular immunotherapy for melanoma. [Read the Full Post]
Tanespimycin as antitumor therapy
0 views | Jan 07 2020
Dimopoulos MA et al. indiacated that tanespimycin represents a promising new agent for the treatment of relapsed/refractory MM. Results of ongoing and future trials will determine the role of tanespimycin both in MM and other malignancies, including breast cancer. [Read the Full Post]
Hsp90 inhibitors induce the unfolded protein response in bovine and mice lung cells
176 views | Dec 19 2019
Kubra KT et al. demonstrated that Hsp90 inhibition triggers the activities of the unfolded protein response, and suggests that this molecular machinery contributes in the protective action of Hsp90 inhibitors in the lung microvasculature. [Read the Full Post]
NVP-AUY922, a novel HSP90 inhibitor, inhibits the progression of malignant pheochromocytoma in vitro and in vivo
0 views | Dec 19 2019
Lian J et al. indicated that NVP-AUY922 exhibits potent anti-PCC activities in vitro and in vivo and represents a promising therapeutic small molecule for treating malignant PCC. [Read the Full Post]
Activity of the Hsp90 inhibitor luminespib among non-small-cell lung cancers harboring EGFR exon 20 insertions
169 views | Dec 18 2019
Piotrowska Z et al.showed that this study met its primary end point, suggesting that luminespib may be an active therapy for advanced NSCLC patients with EGFR ins20. Luminespib is generally well-tolerated, though reversible low-grade ocular toxicity is common. Further study of luminespib and other hsp90 inhibitors in this population is warranted.
