Novel compounds useful for inhibiting spermatogenesis and cancer treatment, and in particular as inhibitors of heat shock proteins and / or elongation factor 1 alpha.

The invention discloses a nano-carrier for drug and gene co-delivery and a preparation method and application thereof, and particularly relates to a co-delivery nano-carrier TCPL-siRNA-PPX for simultaneously carrying a chemotherapeutic drug and a gene-based drug. A polymeric prodrug carrier TCPL, siRNA and a multifunctional polyanionic polymer PPX are self-assembled by electrostatic adsorption between ingredients to form the drug delivery system; a drug and a gene can be targeted to be delivered to the same tumor cell, and moreover, siRNA is released in cytoplasm to silence the Bc1-2 protein, promoting apoptosis and releasing the inhibition of Bcl-2 on lonidamine; the chemotherapeutic drug acting on mitochondria, lonidamine, is delivered to the mitochondria; both cooperatively trigger the apoptosis of the mitochondrial pathway, jointly killing the tumor cell. By in-vitro and in-vivo activity evaluation, the invention proves that the system is better than the simultaneous delivery of each single component, can remarkably increase anti-cancer activity, and has a definite synergistic treatment effect.

Lonidamine derivatives can be useful in methods of treating, inhibiting, and / or preventing polycystic kidney disease (PKD). Accordingly, lonidamine derivatives can be administered in a therapeutically effective amount for inhibiting, and / or preventing polycystic kidney disease (PKD) in the subject. This can include administering a therapeutically effective amount of the lonidamine derivatives for inhibiting CFTR and / or Hsp90 or biological pathway thereof. Also, the method can include administering the lonidamine derivatives in a therapeutically effective amount for inhibiting ErbB2, Src, Raf-1, B-Raf, MEK, Cdk4, NKCC1, or combinations thereof. For example, the therapeutically effective amount of the lonidamine derivatives can be configured so as to provide a concentration in or adjacent to a kidney cell of about 0.25 uM or more or less.

The invention relates to the fields of chemical pharmacy and pharmaceutic preparation, in particular relating to a compound Lonidamine amorphous multielement solid dispersion and a preparation method thereof. The solid dispersion in the invention is characterized by being prepared from Lonidamine, a surfactant and a solid dispersion carrier, wherein the Lonidamine is dispersed in the solid dispersion carrier in an amorphous mode. The Lonidamine amorphous multielement solid dispersion in the invention has the advantages of non-toxic auxiliary materials, no pollution and simple and convenient operation, and greatly improves the solubility of the Lonidamine, thus enhancing the bioavailability and ensuring good thermodynamic stability of preparations.

Poly-N-(2-hydroxypropyl)methacrylamide-lonidamine macromolecule prodrug and preparation method thereof. The invention discloses a compound represented by the general structural formula (I), wherein m=10-500 and n=10-500. The PHPMA-LND macromolecular prodrug synthesized by the present invention can not only increase the water solubility and half-life of the small molecule drug LND, and has a high drug delivery rate, but also can effectively control the release of its drug in the human body, reduce the number of times patients take medicine, and reduce its side effects.

The invention discloses a Prussian blue nano-particle coated with zinc glutamate loaded with triphenylphosphine-lonidamine and a preparation method thereof, comprising a Prussian blue nano-core whose surface is coated with at least A zinc glutamate layer, the surface of the outermost zinc glutamate layer has a load layer loaded with triphenylphosphine-lonidamine, and the load layer is covered with a tumor cell membrane layer. The present invention has the ability to target tumor cells, has a long circulation time in the body, and can gather in mitochondria and cause dysfunction, reduce the synthesis of ATP, down-regulate the synthesis of various heat shock proteins, and cause cell apoptosis at the same time, effectively enhancing the low-temperature light therapy of tumors. Efficacy of heat therapy.

The invention relates to a preparation method of 1H-indazole-3-carboxylic acid derivatives, grasetron and lonidamine. The 1H-indazole-3-carboxylic acid derivative is a compound with the structure of formula (1) and formula (2), and the main structural feature is that it has a 1H-indazole-3-carboxylic acid amide skeleton and a 1H-indazole-3 ‑Carboxylate backbone. The 1H-indazole-3-carboxylic acid derivative can be synthesized from simple anthranilamide or anthranilate as a starting material. 1H-indazole-3-carboxylic acid derivatives are key intermediates in the synthesis of various drugs, such as granisetron, lonidamine, etc. The 1H-indazole-3-carboxylic acid derivatives and drug molecules granisetron and lonidamine involved in the present invention have simple synthesis methods, mild reaction conditions, fast reaction speed, high yield and easy purification.
