Abstract: A process for preparing pharmacologically acceptable salts of N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl amino acids, comprising the steps of: condensing an amino acid with N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanine N-carboxyanhydride under basic conditions; decarboxylating the condensate under neutral to acidic conditions to prepare an N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl amino acid; and converting the product to a pharmacologically acceptable salt thereof, characterized in that a series of procedures up to the formation of a pharmacologically acceptable salt or up to the withdrawal of the pharmaceutically acceptable salt thereof are carried out in an aqueous liquid to inhibit the production of a by-product (3). According to this process, high-quality pharmacologically acceptable salts of N-(1(S)-ethoxycarbonyl-3-phenylpropyl)-L-alanyl amino acids can be prepared in high yields in a cost-effective manner on a commercial scale.

Abstract: Remedies for diseases which function by regulating the expression of a protein induced by a heat shock factor (HSF). Specifically, HSF activity inhibitors or agents inhibiting the induction of the production of a protein regulated by HSF, wherein novel benzo-1,3-dioxole compounds represented by general formula (I) inhibit the transcription of a structural gene having a heat shock element sequence, which is a transcriptional regulatory factor, in a gene region participating in the transcription into RNA, thus inhibit the translation of this gene into a protein and, in its turn, suppress the induction of the production of the RNA, protein, etc. encoded by the gene; and remedies and preventives usable in thermotherapy for cancer and remedies and preventives for stress-induced diseases such as depression. Compounds represented by general formula (I): wherein X is -CH2- and R1 represents C1-2 alkyl, formyl or halogeno; or X is -(CH2)2- and R1 represents C1-3 alkyl, formyl, acetyl, hydrogen or halogeno.
