Unii-56DL1J49LR | CCC1=C2CN3C(=CC4=C(C3=O)COC(=O)[C@@]4(CC)O)C2=NC5=C1C=C(C=C5)OC(=O)N6CCC(CC6)CCN7C=CC8=C7C=CC(=C8)N9C(=NNC9=O)C1=CC(=C(C=C1O)O)C(C)C | PEN-866 is under investigation in clinical trial NCT03221400 (PEN-866 in Patients With Advanced Solid Malignancies). |
Unii-56DL1J49LR | CCC1=C2CN3C(=CC4=C(C3=O)COC(=O)[C@@]4(CC)O)C2=NC5=C1C=C(C=C5)OC(=O)N6CCC(CC6)CCN7C=CC8=C7C=CC(=C8)N9C(=NNC9=O)C1=CC(=C(C=C1O)O)C(C)C | Locnartecan is a miniature drug conjugate composed of the irinotecan metabolite 7-ethyl-10-hydroxy-camptothecin (SN-38) conjugated, through a cleavable linker, to a ligand of chaperone protein heat shock protein 90 (Hsp90), with potential antineoplastic activity. Upon administration of locnartecan, the HSP90 ligand moiety targets HSP90, which allows the conjugate to penetrate, accumulate and be retained in the tumor cell. Once the linker is cleaved, the SN-38 moiety is released in a sustained manner. SN-38 then binds to and inhibits topoisomerase I by stabilizing the cleavable complex between topoisomerase I and DNA, which results in DNA breaks, inhibition of DNA replication and apoptosis. Compared to SN-38 alone, locnartecan preferentially targets, accumulates and is retained in the tumor cells due to its binding to Hsp90, which results in increased concentrations of SN-38 at the tumor site. This allows sustained release of SN-38 and leads to increased and prolonged efficacy while reducing toxicity to normal, healthy tissues. Hsp90, a chaperone protein upregulated and activated in a variety of tumor cells compared to normal healthy tissue, regulates the folding, stability and degradation of many oncogenic signaling proteins. |

Folate-FITC binds to folate receptors, which are overexpressed on the surfaces of many cancer cells including kidney and ovarian cancer cells. Once bound to the cancer cell through the folate moiety of the conjugate, circulating anti-fluorescein antibodies may recognize and bind to the FITC moiety, resulting in antibody-dependent cellular cytotoxicity. |
Seclidemstat | C/C(=N\NC(=O)C1=CC(=CC=C1)S(=O)(=O)N2CCN(CC2)C)/C3=C(C=CC(=C3)Cl)O | Seclidemstat is an orally available, reversible, noncompetitive inhibitor of lysine-specific demethylase 1 (LSD1, or KDM1A), with potential antineoplastic activity. Upon oral administration, seclidemstat reversibly inhibits LSD1, a demethylase that suppresses the expression of target genes by converting the di- and mono-methylated forms of lysine at position 4 of histone 3 (H3K4) to mono- and unmethylated H3K4, respectively. LSD1 inhibition enhances H3K4 methylation and increases the expression of tumor suppressor genes. This may lead to an inhibition of cell growth in LSD1-overexpressing tumor cells. In addition, LSD1 demethylates mono- or di-methylated H3K9 which increases gene expression of tumor promoting genes; inhibition of LSD1 promotes H3K9 methylation and decreases transcription of these genes. |

Upon intradermal administration, fimaporfin is incorporated into the tumor cells' endosome and lysosome membranes. Subsequently, cytotoxic agents are administered and accumulate in the endosomal and lysosomal compartments; upon local activation by light, fimaporfin produces reactive oxygen species (ROS), such as singlet oxygen, damaging endo/lysosomal membranes and accumulated cytotoxic agents are released into the tumor cell cytosol. This photochemical internalization (PCI) method can enhance the efficacy and selectivity of cytotoxic agents. |
(S)-2-(2-(2-Methylindolin-1-yl)-2-oxoethyl)-6-morpholinopyrimidin-4(3H)-one | C[C@H]1CC2=CC=CC=C2N1C(=O)CC3=NC(=CC(=O)N3)N4CCOCC4 | PI3K-beta Inhibitor SAR260301 is an orally bioavailable inhibitor of the class I phosphatidylinositol 3-kinase (PI3K) beta isoform with potential antineoplastic activity. PI3K beta inhibitor SAR260301 selectively inhibits PI3K beta kinase activity in the PI3K/Akt/mTOR pathway, which may result in apoptosis and growth inhibition in PI3K beta-expressing and/or phosphatase and tensin homolog (PTEN)-deficient tumor cells. Dysregulation of the PI3K/Akt/mTOR pathway is frequently found in solid tumors and contributes to increased tumor cell growth, tumor cell survival, and resistance to both chemotherapy and radiotherapy. PI3K beta is the p110-beta catalytic subunit of the class I PI3K. PTEN, a tumor suppressor protein and negative regulator of PI3K activity, is often mutated in a variety of cancer cells. By specifically targeting class I PI3K beta, this agent may be more efficacious and less toxic than pan-PI3K inhibitors. |

PF-477736 | CN1C=C(C=N1)C2=C3C=NNC(=O)C4=C3C(=CC(=C4)NC(=O)[C@@H](C5CCCCC5)N)N2 | CHK1 Inhibitor PF-477736 is a proprietary compound targeting cell cycle checkpoint kinase 1 (chk1) with potential chemopotentiation activity. Chk1 inhibitor PF-477736 inhibits chk1, an ATP-dependent serine-threonine kinase that is a key component in the DNA replication-monitoring S/G2 checkpoint system. By overriding the last checkpoint defense against DNA damaging agent-induced lethal damage, chk1 inhibitor PF-477736 may potentiate the antitumor efficacy of various chemotherapeutic agents against tumor cells with intrinsic checkpoint defects. |
Pamiparib | C[C@]12CCCN1CC3=NNC(=O)C4=C5C3=C2NC5=CC(=C4)F | Pamiparib is under investigation in clinical trial NCT03933761 (Pamiparib in Fusion Positive, Reversion Negative High Grade Serous Ovarian Cancer or Carcinosarcoma With BRCA1/2 Gene Mutations If Progression on Substrate Poly ADP Ribose Polymerase Inhibitbor (PARPI) or Chemotherapy). |
Pamiparib | C[C@]12CCCN1CC3=NNC(=O)C4=C5C3=C2NC5=CC(=C4)F | Pamiparib is an orally bioavailable inhibitor of the nuclear enzyme poly(ADP-ribose) polymerase (PARP), with potential antineoplastic activity. Upon administration, pamiparib selectively binds to PARP and prevents PARP-mediated repair of single-strand DNA breaks via the base-excision repair (BER) pathway. This enhances the accumulation of DNA strand breaks, promotes genomic instability, and eventually leads to apoptosis. PARP is activated by single-strand DNA breaks and, subsequently, catalyzes post-translational ADP-ribosylation of nuclear proteins which then transduce signals to recruit other proteins to repair damaged DNA. Pamiparib may both potentiate the cytotoxicity of DNA-damaging agents and reverse tumor cell chemo- and radioresistance. |

Mantle cell lymphoma is an aggressive mature B-cell non-Hodgkin lymphoma that is associated with early relapse, poor clinical outcomes, and long-term survival. BTK is an enzyme that plays a role in oncogenic signalling pathways, where it promotes the survival and proliferation of malignant B cells. Compared to the first-generation BTK inhibitor [ibrutinib], zanubrutinib displays higher potency and selectivity for BTK with fewer off-target effects. Due to this enhanced selectivity towards BTK, zanubrutinib belongs to the second-generation BTK inhibitor drug group that also includes [acalabrutinib], which was approved by the FDA in 2017. Zanubrutinib was granted accelerated approval by the FDA in November 2019 based on clinical trial results that demonstrated an 84% overall response rate from zanubrutinib therapy in patients with MCL, which measures the proportion of patients in a trial whose tumour is entirely or partially destroyed by a drug. It is currently marketed under the trade name BRUKINSA™ and is available as oral capsules. In August 2021, the FDA granted accelerated approval to zanubrutinib for the treatment of adults with Waldenström’s macroglobulinemia. This indication is valid in the US, Europe, and Canada. In September 2021, zanubrutinib was granted another accelerated approval for the treatment of relapsed or refractory marginal zone lymphoma who have received at least one anti-CD20-based regimen. In October 2022, the EMA's Committee for Medicinal Products for Human Use (CHMP) recommended zanubrutinib be granted marketing authorization for the treatment of chronic lymphocytic leukaemia. |

Zanubrutinib | C=CC(=O)N1CCC(CC1)[C@@H]2CCNC3=C(C(=NN23)C4=CC=C(C=C4)OC5=CC=CC=C5)C(=O)N | Zanubrutinib is an oral inhibitor of Bruton’s tyrosine kinase that is used in the therapy of refractory mantle cell lymphoma. Zanubrutinib has been associated with a low rate of serum enzyme elevations during therapy, but has not been linked to cases of clinically apparent acute liver injury although it may pose a risk for reactivation of hepatitis B in susceptible patients. |
Zanubrutinib | C=CC(=O)N1CCC(CC1)[C@@H]2CCNC3=C(C(=NN23)C4=CC=C(C=C4)OC5=CC=CC=C5)C(=O)N | Zanubrutinib is an inhibitor of Bruton's tyrosine kinase (BTK) with potential antineoplastic activity. Upon administration, zanubrutinib inhibits the activity of BTK and prevents the activation of the B-cell antigen receptor (BCR) signaling pathway. This prevents both B-cell activation and BTK-mediated activation of downstream survival pathways, which leads to the inhibition of the growth of malignant B-cells that overexpress BTK. BTK, a member of the Src-related BTK/Tec family of cytoplasmic tyrosine kinases, is overexpressed in B-cell malignancies; it plays an important role in B-lymphocyte development, activation, signaling, proliferation and survival. |
Repotrectinib | C[C@H]1CNC(=O)C2=C3N=C(C=CN3N=C2)N[C@@H](C4=C(O1)C=CC(=C4)F)C | Repotrectinib is an orally available inhibitor of multiple kinases, including the receptor tyrosine kinase anaplastic lymphoma kinase (ALK), c-ros oncogene 1 (ROS1), the neurotrophic tyrosine receptor kinase (NTRK) types 1, 2 and 3, the proto-oncogene SRC, and focal adhesion kinase (FAK), with potential antineoplastic activity. Upon oral administration, repotrectinib binds to and inhibits wild-type, point mutants and fusion proteins of ALK, ROS1, NTRK1-3, SRC, FAK and, to a lesser extent, other kinases. Inhibition of these kinases leads to the disruption of downstream signaling pathways and the inhibition of cell growth of tumors in which these kinases are overexpressed, rearranged or mutated. |

Upon administration, and although the exact mechanism of action has yet to be fully elucidated, defibrotide induces the release of prostaglandin I2 (PGI2), E2 (PGE2), and prostacyclin and reduces the expression of adhesion molecules on endothelial cells. This relaxes the smooth muscle of blood vessels and prevents platelets from adhering to each other and to the endothelium. This protects the endothelium lining bloods vessels. Defibrotide increases tissue plasminogen activator (t-PA) and decreases plasminogen activator inhibitor-1 activity. This increases the activity of plasmin, prevents blood clot formation and dissolves blood clots. |

PI3K alpha/beta inhibitor BAY1082439 selectively inhibits both PI3K alpha, including mutated forms of PIK3CA, and PI3K beta in the PI3K/Akt/mTOR pathway, which may result in tumor cell apoptosis and growth inhibition in PI3K-expressing and/or PTEN-driven tumor cells. By specifically targeting class I PI3K alpha and beta, this agent may be more efficacious and less toxic than pan PI3K inhibitors. Dysregulation of the PI3K/Akt/mTOR pathway is frequently found in solid tumors and results in increased tumor cell growth, survival, and resistance to chemotherapy and radiotherapy. PIK3CA, one of the most highly mutated oncogenes, encodes the p110-alpha catalytic subunit of the class I PI3K. PTEN, a tumor suppressor protein and negative regulator of PI3K activity, is often mutated in a variety of cancer cells. |

Upon administration, the IRS1/IRS2/STAT3 inhibitor NT219 specifically targets and binds to IRS1/2 and STAT3. Inhibiting IRS1/2 prevents IRS1/2-mediated signaling pathways and other tumor survival pathways. Inhibiting STAT3 prevents nuclear translocation of STAT3 and the STAT3-mediated regulation of oncogenes expression. This causes tumor cell apoptosis and inhibits tumor cell proliferation. IRS1/2 and STAT3, oncogenic drivers that are upregulated in a variety of human cancers, play key roles in uncontrolled tumor cell proliferation and tumor resistance. |
